Most Common Engine Problems

Most Common Engine Problems

If you are looking for the most common engine problems, this post should help! When your engine fails, it isn’t a good thing. Not only will your car be down, but it can be hard to diagnose and even harder to repair. Whether your engine is making weird noises, misfiring, or overheating, the cause could be one of many issues.

Most Common Engine Problems

You shouldn’t think of the check engine light as a death omen for your car, but you should think of it as an indication that something on your car needs some attention. Your car diagnostician may find any of the issues below.

Missing or loose gas cap.

Replacing or tightening the gas cap is going to be the cheapest and easiest fix for your car in its lifetime. However, it is also important. A missing or loose gas cap can cause your gas to evaporate from your car, which decreases the gas mileage which could cost your hundreds of dollars.

Worn Spark Plug.

It may be small but its important. The spark plug is what makes your vehicle move forward. It has a function to ignite compressed gas within your engine. Worn spark plugs will make a weak spark which may prevent your engine from igniting or cause it to do so during the wrong stage. Misfiring will affect your engine and gas mileage and can cause a lot of damage.

Clogged radiator.

Dirty coolant may cause many issues. If your radiator gets filled with sediment from dirty coolant, then it can cause your engine to overheat. Your radiator can get corroded if you use hard water in it.

Coolant loss.

Normally coolant loss is the most common reason for overheating. If your engine is constantly overheating, then the high temperature could cause major damage that can’t be repaired. Prevention is the best treatment, so avoid this damage by ensuring that the coolant is clean, and that the cooling system is in good condition for operating.

Poor compression.

If fuel and air aren’t properly compressed, your engine can’t complete the combustion process. If the valves aren’t being sealed properly, the piston rings are worn, or the cylinder has a hole, there could be an air leak which causes lack of compression.

Faulty or broken oxygen sensor.

This sensor measures just how much oxygen hasn’t been burned in the exhaust. It will then tell the data system just how much gas is in the gas tank. A problem with an oxygen sensor means that your car gets incorrect information. This often causes lower gas mileage.

Spark knock.

This is a type of combustion that is caused by the build up of too much pressure and heat in the combustion chamber. Whenever this happens, you will hear a pinging or metallic knocking noise. A small amount of this won’t cause any major damage but the heavy knocks and prolonged detonation can cause some major damage to the engine. It can crush rod bearings, crack rings, punch holes in the pistons, pound out piston ring grooves, and even blow a head gasket. Prolonged knocking noises are a certainly something to be concerned with.

Dirty oil.

Oil can even build up can leave some nasty deposits on the spark plugs, combustion chambers and intake valves. It can be ruing the bearings by leaving debris which will embed on the surface. If the oil filter is missing or clogged, then this could be problem.

Oil pump failure.

A failing oil pump can cause oil starvation which will damage any engine. Overhead cam engines are at risk for this, because the valve train and cam are further from the pump than a pushrod engine. Oil needs to be the proper viscosity which means it needs to be light enough to move fast.

Poor lubrication.

Your car will need oil between moving parts. Not only does this reduce friction, it also removes heat. Having a regular oil change is important to the functioning of your car. Failing to make sure you have proper lubrication can cause your car to overheat and the parts to seize up, so keep your oil at the recommended level. Low levels could mean burning or a leak.

Bad air/fuel mixture.

The first and maybe most obvious thing is if you’re out of fuel.  If it’s on “E” then you’ll need to head on down to a gas station. There can be a problem with your vehicle’s air intake.  If the intake isn’t letting air into your engine, it cannot operate properly.  There can also be problems caused by water that’s got into your gas tank.  This will cause the fuel to not ignite.  Lastly your vehicle may be running “rich” (too much gas) or too “lean” (not enough gas) in the air/fuel mixture.

How To Tell If Car Engine Is Blown

We’ve all heard people talk about blowing an engine, but what does that mean?  It’s easiest to understand a blown engine as any type of damage or failure which requires an overhaul or replacement of the engine.  There’s a number of various components that once damaged constitute serious enough repair that most would agree it’s “blown”.

Cracked Engine Block

One of the most obvious signs that you’re engine is blown is when the engine block cracks.  The engine block is the larger housing that defines the internal combustion engine.  If it cracks the engine cannot contain the pressures of fuel exploding and pushing the pistons to produce power.

Signs to watch for include if your vehicle is overheating, if you have white smoke coming from the exhaust, and if you see coolant leaking from the side of the engine.

Pistons, Rings, & Cylinders

The pistons are what does the heavy lifting of producing the power to move your vehicle.  They go up and down within the cylinder walls and the rings close up the gap between the piston and the walls.  If any of this is damaged the engine will have serious failures and need to be repaired or replaced.

Symptoms to watch for with your pistons, rings, and cylinders are loud rattling sounds, blue smoke in exhaust, oil caps popping off, when your engine won’t idle smoothly, and if you fail an emissions test.

Rods, Bearings, & Pins

Other components in your engine that transfer the power from the pistons such as the rods, bearings and pins will cause a blown engine if they fail.

Things to watch for include tapping and ticking sounds, low oil pressure, pulsing, metal shavings in the engine oil, throwing a rod (extremely dangerous), and rattling when you accelerate.

How the Engine Works

Your check engine light can be an anxiety trigger for any driver. It could mean anything from a missing gas cap which is a cheap and easy fix to needing a major repair which can be expensive. The whole issue is that it can be made worse by the fact that most car owners don’t really have a great sense of how their engine works. What can be more confusing than a large jumbled mess of metal, tubes and wires?

Here is a breakdown. Your engine works from the inside of your car, which is why its call an internal combustion engine. Basically, the job of the engine is to convert the gas into energy, which makes your car go. In the newer hybrid and electric cars, the energy source is going to be different, but the outcome is still the same. The same goes for diesel engines. It is just a universal truth: Without a working engine, your car is going to be a heavy and useless pile of metal.

Having regular maintenance could seem to be pricy, but it is also important to do to keep your car in good working order. If you want to get the most out of your car, then ensure that you keep up with getting routine oil changes and other various maintenance and be sure to address other problems that occur as soon as they happen.

How To Pass Emissions An Test

To give your vehicle the best chance at passing the emissions test follow these tips.  By doing a little preparation you can save yourself the headache of getting your vehicle retested.  If you’ve got more serious problems with your vehicle you will likely need to have professional automotive repair to get your vehicle to pass emissions.

Change Engine Oil

Old dirty oil in your engine can release extra pollutants which can cause you to fail your emissions test.  It’s a good practice to have your oil changed before an emissions test.

Check Gas Cap Seal

One of the most common reasons people fail an emissions test is the gas cap.  Gas cap seals are exposed to heat, cold, rain, snow and the seals break down.  If air is passing by your gas cap it can cause your vehicle to throw a check engine light and fail your vehicle in an emissions test.

Have A Tune Up

Having your vehicle tuned up about 2 weeks before you need to get the test is a great precaution also.  Your vehicle benefits from regular maintenance and it will increase the chances of passing you emissions test.  Filters will be changed and your vehicle will be running at peak performance.

Check Tire Pressures

In some states your vehicle will be ran on rollers to test emissions as if  you were moving.  This is called a dynomometer.  If your tires have low pressure it could cause your motor to release higher levels of pollutants at speed.

Add A Fuel Additive

Fuel additives help clean carbons deposits out of your vehicle’s exhaust and intake system. If you’ve got extra carbon deposits around fuel injectors, cylinders, or in the exhaust it can cause your vehicle to fail an emissions test.

Use The Vehicle

If it is a vehicle you don’t normally drive, but want to get the registration done, you will need to make sure you drive it regularly for 2 weeks leading up to your testing.  This helps clear out the exhaust system and catalytic converter from carbon and other harmful pollutants.

Drive On Highway 20 Min Before Testing

On the day of testing you’ll need to drive the vehicle on the highway for about 20 min to warm up the motor.  This makes it so when you arrive at the emissions testing center you’ll be ready to pass with flying colors.

Reasons To Fail Emissions Test

There are 6 main reasons vehicles fail emissions testing.  A check engine light is a red flag that will cause you to fail along with bad O2sensors, too rich fuel to air mixture, bad EVAP systems, leaky, or incorrect fuel metering.

Check Engine Light

The check engine light in your vehicle comes on for numerous reasons.  If it is on you should stop by our shop and let us read the code to figure out what is happening with your vehicle.  Sometimes it can be as simple as needing a new gas cap to something more serious that if ignored can result in costly repairs.

Bad 02 Sensors

Vehicles today rely on O2 sensors to monitor exhaust fumes.  When they are not working properly the vehicle will likely have a rough idle or decrease in engine power.  You will also lose mountains of MPG efficiency if your O2sensors are not working properly.  If your vehicle is burning too much fuel it will not pass emissions testing as the toxicity of the exhaust will be too high.

Rich Fuel to Air Mixture

When gasoline is injected into your engine it is mixed with a proportion of air.  This is called the “air to fuel mixture”.  How much fuel is used to in each cycle of the pistons affects your fuel mileage, power, an carbon monoxide content in your exhaust.  If you are burning too much fuel you will not pass emissions tests.

Bad EVAP System

Your Evaporative Emissions Control System, or EVAP, stops gas fumes from being released into the atmosphere by your vehicle.  When vacuum hoses are cracked, loose, or broken it will cause the check engine light to come on.  Even a loose or broken gas cap will cause the EVAP system to throw a check engine light and prevent you from passing your emissions test.

Leaky Exhaust

Exhaust leaks will wreak havoc on a vehicle’s ability to pass an emissions test.  If your exhaust system is leaking it will make the O2 sensor read incorrectly.  If the exhaust from your engine isn’t being passed through the catalytic converter it is being released into the atmosphere in categorically illegal levels.  If your exhaust system is leaking, we can repair it so you will pass the emissions test in Arizona.

Incorrect Fuel Metering

How much fuel your vehicle uses is also part of emissions testing.  If your vehicle uses too much fuel compared to it’s make and model you will likely not pass your emissions test.  The right amount of fuel is sent to the engine to make it run smoothly.  If a fuel injector or engine control unit is malfunctioning it will use too much fuel and make it hard to pass an emissions test.

How Much Does Emissions Repair Cost?

The cost to repair your vehicle so it will past emissions testing will depend on what is preventing it from passing.  If it is simply a gas cap, it will cost around $30. In contrasts it costs about $200 dollars to fix an O2 sensor in most of today’s vehicles.  If the catalytic converter needs to be replaced it will cost over $1,000 dollars.  You will save money the sooner you bring your vehicle in when the check engine light turns on.  Small issues like O2 sensors can lead to the bigger more expensive problems such as replacing your catalytic converter.

Transmission Problems, Solutions, and Repair Costs Scottsdale AZ

Transmission Problems, Solutions and Repair Costs 2018

A car requires continuous maintenance and there are a whole host of things that can go wrong and will need repairs sooner or later. So it helps to know what’s what, and what’s wrong when you are confronted with a malfunctioning vehicle.

View Our Special Offers

Below, we have listed some of the most common transaxle and transmission problems that people face, and have also outlined what causes them, the symptoms you can recognize them by, and the average cost of repair. When you know exactly what’s wrong with your vehicle, you can assess whether it’s a problem that needs to be fixed by the repair-shop, or if you can find an easier and cheaper fix if you do it yourself. You are also less like to get ripped off or overcharged by repair-shops when you know what the problem is and how much the repairs should cost.

PROBLEM: TRANSMISSION FLUID RUNNING LOW

This normally happens if your transmission fluid leaks for some reason, and can be recognized by a slipping, overheating or failed transmission, a delay in engaging the gear, and hard or irregular shifts or none at all.

The easiest repair is to refill transmission fluid, if no other damage has been done. A repair-shop will do it for $20-$30, while DIY will cost you $5-$10 per Quart ATF.

If the lack of transmission fluid has caused permanent problems to other mechanisms within the vehicle, this will involve further repair costs for the affected systems. It is also important to note that transmission fluid is not consumed or burned by the vehicle, so low transmission fluid indicates a leak which will need to be fixed.

PROBLEM: BURNT, DIRTY OR OLD FLUID

This will happen because of lack of servicing, blocked filters, or overheating, and can be identified by a slipping transmission, overheating, delays in engaging the gear, malfunctioning or no shifts, or if transmission fails.

The best repair is to have fluid and fluid filter changes or do a fluid flush. Having the fluid and filter replaced at a repair-shop will cost you around $120-$225, and doing it yourself will cost you $45-$55. For a fluid flush, a repair-shop is likely to charge you $140-$320, while you can DIY for around $65-$90.

It should be noted that burnt fluid may sometimes cause internal damage if not identified at the right time. This can be determined by checking if there is clutch or metal debris in the fluid pan, and damaged parts will have to replaced.

PROBLEM: LEAKED TRANSMISSION FLUID

There may be various causes for this, most of them often external damages, which can be repaired easily for a reasonable cost. A fluid leak, as mentioned above, can be identified by a low fluid level.

The easiest fix is to get the leak fixed and refill the fluid. A repair-shop will charge you $50-$500 for this, if the leak is external, and DIY will cost you $25-$100.

If the cause of the leak is internal, however, it will have to be repaired at the shop as the transmission needs to be taken out of the vehicle. This repair may cost you over $500.

PROBLEM: TRANSMISSION SLIPPING

This will be caused due to the fluid running low, a failure in the Solenoids, worn out clutches, or if the fluid is burnt, dirty or old. It can be identified by the engine’s high RPM but a slower speed regardless, an overheating transmission, or if slipping is experienced in between shifts.

The first thing that need to be done if this is experienced is to diagnose the problem and identify its source, which could be any of the problems outlined above. Having this done at the repair-shop will cost you $75-$125, while diagnosing the problem yourself will cost you nothing but a little bit of time. For a detailed diagnostic report, a transmission scan can be undertaken at the repair-shop.

PROBLEM: MALFUNCTIONING OR ABNORMAL SHIFTS, WRONG GEAR SHIFTS

If the transmission fluid is old, dirty, burnt or running low, or if an electrical circuit is open, or the solenoids fail, this can lead to a number of shift problems, like abnormal shifts or the vehicle shifting into the wrong gear.

Like before, the key is diagnosis, which can be performed at the repair shop for $75-$125 (price range includes cost for a transmission scan) or at home for no cost at all.

PROBLEM: FAILED AUTOMATIC GEAR SHIFTING WHEN MANUAL SHIFTING WORKS FINE

This could be caused if there’s an open electrical circuit, if the PCM or TCM fail, or if the speed or other sensors stop working, and can be recognized rather obviously if the automatic gear shifting mechanism has stopped working but the gear can still be shifted manually.

Initial diagnosis can be carried out at home for no cost but if that does not reveal anything, the car will have to be taken to the repair-shop so that a diagnosis of electrical problems or computer and sensor issues can be undertaken. This will cost around $75-$125.

PROBLEM: OTHER IRREGULAR SHIFT PROBLEMS 

If you notice that the transmission is downshifting randomly and then going back to normal as well, this could be cause by an electrical malfunction, or if the speed, transmission range, or throttle position sensors stop working.

Initial assessment can be carried out at home and the vehicle can be taken to the repair-shop for a full scan of electrical and computer systems, and all sensors. A custom diagnosis will cost between $75-$125.

PROBLEM: TRANSMISSION SLIPPING OUT FROM GEAR WHEN CAR IS WARM 

If you notice that the transmission is slipping out of gear every time the vehicle gets warmed up, this is probably due to fluid passing through a leakage in the internal seals not allowing pressure build up.

In such a situation, the best course of action is rebuilding or replacing the transmission. The repair-shop will normally charge you $1,600 to over $3,500 for rebuilding, and $1,900 to over $3,800 for rebuilding the transmission. You can do this at home, in which case rebuilding the transmission will cost you between $400-$700 and replacing it will cost you $1,200 to over $3,000.

The prices mentioned above are true if you purchase a remanufactured transmission. Cost of a used transmission will be must less.

PROBLEM: OVERHEATING 

SYMPTOM(S): If you notice smoke or a burning smell, most likely caused by burning coolant, oil or transmission fluid, or if the transmission fails, the vehicle has most likely overheated. This can be caused if the transmission fluid is running low, or if it is dirty or burnt, if the filter is blocked, or if the vehicle has been driving under immense load. Other causes may include cooling lines or oil cooler malfunction, overheated engine, slipping, and failure of the transmission fluid pump.

It is important that overheating is identified and diagnoses immediately, as it can cause permanent damage to the vehicle. If you are able to diagnose the source of the overheating at home, you’ll save on diagnosis fees, which will normally be around $75-$125 at the repair shop.

PROBLEM: FORWARD GEAR FAILURE

Internal problem stopping a pressure build up or a problem in the valve may cause the transmission’s forward gears to stop working, while the reverse gear may still be functioning.

The first step is a proper diagnosis of the problem, for which the repair-shop will charge you $75-$125. When the diagnosis has revealed the source of the problem, you can have the valve replaced at the repair shop for $375 to above $1,000, or you can purchase and install it yourself, which will cost you $250 to above $1,000.
If it’s the transmission that needs rebuilding, the repair-shop will charge you $1,600 to above $3,500 for the task, or you can rebuild it yourself for $400-$700.

It must be noted that if it’s a problem in the valve body, it will normally show up only under a transmission scan which the repair facility will have carry out.

PROBLEM: REVERSE GEAR FAILURE

Opposite to a similar problem mentioned earlier, if the reverse gear transmission has stopped working while the forward gears may still be working, this could be caused by a leakage in the valve body that is not allowing the required pressure to build up.

Having the problem diagnosed at the repair-shop will be around $75-$150, and valve repair costs will be the same as those mentioned above.

PROBLEM: TORQUE CONVERTER MALFUNCTION 

If you have been using your vehicle for towing heavy objects or driving it under other harsh conditions, or if the torque converter is worn out or hasn’t been installed properly, this may cause the torque converter to malfunction. You can identify this if you experience shuddering in the vehicle, if the shifts are malfunctioning, if there is delay in engaging the gear leading up to no engagement at all, if you hear a strange whining sound when firing up the vehicle, or if the engine revs up more than the vehicle accelerates at start-up but gets better later.

Diagnosis at a repair shop, as mentioned above, will cost around $75-$125, and you will be charged $600 to above $1000 for having the torque converter replaced. If you purchase and replace it yourself, it will cost you around $145-$250.

It is important to note that the torque converter may, on some occasion, disintegrate upon failure. This can be identified by clacking or grinding noises from the transmission area. When this is heard, turn off the engine immediately or serious damage may be caused to the transmission.

Furthermore, even if the torque converter has started failing, your vehicle will still continue to work for quite some time before the converter fails completely. But driving the vehicle in this condition is dangerous as it may cause it to internally disintegrate when it fails, resulting in the debris getting mixed with the transmission fluid and causing serious damage to the transmission.

PROBLEM: SHIFTER LEVER LOCKING ITSELF PARK POSITION 

If your shifter level locks itself in the park position on occasion, this may be due to a fault in the brake-pedal position or shift interlock switches, or if a fuse has blown.

This will have to diagnosed and repaired, for which the repair-shop may charge you $35-$65 and $50-$250 respectively. Diagnostic charges may be waived if the repair-shop carries out the repairs as well. The repair cost will be determined by the system that needs to be repaired. If it’s a simple brake-light switch replacement, it won’t cost you as much as having the shift interlock switch replaced.

PROBLEM: VEHICLE MOVES EVEN WITH SHIFTER IN PARK POSITION

If this happens, it is probably caused by a worn out or damaged parking pawl, or a bad rear U-joint.

Diagnostic at the repair-shop will cost around $50-$65, with parking pawl and U-joint replacement charges coming up to about $500-$1,000 and $75-$115 respectively. Diagnostic charges may be waived if the repair-shop carries out the repairs as well. If you decide to replace the parking pawl yourself, it will cost you $45-$90, and replacing the U-joint yourself will be $10-$25 on average.

PROBLEM: LINKAGE PROBLEM IN THE SHIFTER

This will be signified by the vehicle rolling forward even with the shifter in neutral position, and can happen if the shifter linkage is loose, if the shift indicator is directed towards a wrong gear, or if the shifter cable has been damaged.

The solution is pretty simple. You can diagnose the cause of the problem yourself or have it taken to the repair-shop for diagnoses, which will cost you $40-$50 in diagnostic fees. If the cause turns out to be a loose shifter linkage, you can tighten it yourself at no cost, or have the repair-shop do it for $50-75. If the condition is being caused by a damaged shifter cable, the repair-shop will charge you $125-$250 for replacement, or you can purchase and replace it yourself for around $35-$80.

Knowing what ails your vehicle and being able to identify a problem and diagnose its cause will give you confidence when dealing with a repair-shop and save you considerable amount of money on repairs.

Common Mercedes Problems

Common Mercedes Problems

If you’re searching for Mercedes repair you’re likely suffering from one of the common Mercedes problems.  Bridwell Automotive Center is Scottsdale, Arizona’s premier Mercedes repair shop.  Our team of fully certified and trained repair technicians understand the common problems with Mercedes and know the right way to fix them, the first time.  Call today to schedule Mercedes repair in Scottsdale.  Schedule the repair of your Mercedes by calling (480) 948-4781.

Common Mercedes Problems

Despite being one of the finest made brands of vehicles Mercedes still have common problems.  Here’s a list of common issues and the likely culprits causing problems with your Mercedes.

Ignition Will Not Turn

If your Mercedes key slides into the ignition barrel but will not turn it is very frustrating, especially if you’re in a hurry.  Unfortunately, there’s no magic fix and if this happens you’re looking for a trustworthy tow company.  Many times, the problem causing this is a faulty EIS module.  Before it completely fails you will usually notice a few times where you notice the wear, get it looked at ASAP to avoid getting stuck and needing a tow.

Engine Cranks But Won’t Start

A lot of models of Mercedes end up with this problem.  Your engine will continue to crank but never actually starts the vehicle.  Many times, this is caused by the crank shaft position sensor.  Your engine management system looks for the indication of the TDC from the position sensor.

If it isn’t working correctly the signal isn’t received and the vehicle will not start.  One warning sign before it just won’t start is longer crank times.  So, if you’ve got a Mercedes that’s taking longer and longer to start you may consider some preventative maintenance.

Vehicle Will Not Shift Out of Park

A common problem with the S class and E series of Mercedes it can be a frustrating issue.  Your vehicle will fire up and run, but you will not be able to shift the vehicle out of park and into reverse or drive.  It is commonly caused by a faulty selector module.  Again, there are warning signs before complete failure. If you’ve experienced trouble shifting your Mercedes out of park, get it looked at before it fails.

Check Engine Light On & Running Rough

While a check engine light is caused by wide variety of problems a Mercedes that is running rough is a sign of misfires.  It could be a single cylinder or more than one that isn’t working properly and causing your misfires.  In Mercedes vehicles one of the most common causes of running rough is the mass air flow meter or “MAF”.

While the engine management system usually keeps your motor running smoothly a problem with the mass air flow meter could be feeding it bad information.  One sign of a bad MAF is a significant change in fuel consumption.

Rattling During Startup

Some models of Mercedes engines will have a rattle during the first 15 seconds after starting.  This is exacerbated by colder weather conditions.  In many cases the rattle is caused by a belt tensioner which is worn.  If it continues past the first 15 seconds, the culprit may be the water pump pulley.  See that these issues are resolved as they have the potential of leaving you road side looking for a tow.  You’ll either not have a belt or the vehicle will have overheated.

Fluid Leaks Under Center of Vehicle

Older Mercedes vehicles will frequently have transmission leaks that show up under the center of where the vehicle is parked.  If you find a red fluid in this area it is most likely a leak from the electrical transmission plug on the side of the transmission.  Another common source of transmission leaks is the transmission pan.  Generally, the leaks are gradual and may only be a few drops, but losing your transmission fluid will result in absolutely catastrophic damage.

Common BMW Problems

Common BMW Problems

While BMW’s are some of the finest vehicles around every manufacturer will have problems that are more common than others.  This post will talk about common BMW problems and solutions.  Some of these problems are common to just about every type of vehicle and others are more specific to the BMW brand.

Top 5 Most Common BMW Problems

BMW’s don’t have a lot of problems, but when they do these are the top 5 most common problems.  The majority of these issues are usually inexpensive to have repaired and don’t take very long to do.  Depending on each of the issues and the reason there is a problem the cost of repairing these problems will vary as will the time needed to fix them.  Our team specializes in providing affordable repairs and quick turnaround to keep you moving.

Slow or Stuck Windows

The 3 Series of BMW is most prone to this problem.  Windows stop working many times because of a damaged or worn window regulator.  The window regulator is the system which uses electricity to power your windows to go up and down.  The most common problem is when the regulator clips break.

Wild Window Wipers & Electronics

Another common problem is window wipers with a mind of their own.  While automatic window wipers are great for sudden rain or snowstorms; window wipers that turn on by themselves can be distracting.  Other electronic systems such as the radio, indicators, heat seats and others are also possible problem areas.

Check Engine Lights

If your check engine light is on there is a good chance you need new injectors, ignition modules, or even a new clutch.  When BMW’s show a check engine light these are the most common reasons.  Most of these repairs are fairly reasonable in cost and won’t take terribly long to repair.

Remote Not Operating Locks

BMW remote key fobs not locking or unlocking the doors is another common problem.  This can be an issue with dead battery, broken fob, or the vehicle’s electronics needing adjustment.

Cracked Wheels

While any size wheel can crack the most common type that cracks on the BMW is the 19 inch alloys with run flat tires.  The alloy can crack if road hazards are hit at high speed such as potholes, curbs, or construction areas.  If this happens there is a chance of the alloy puncturing the tire.

BMW Reliability

BMW is frequently purchased due to its high reputation for quality and reliability.  According to Consumer Reports BMW ranks highly for reliability.  Reliability is a measure of how many repairs a vehicle will need within a timeframe. 80% of BMW’s score higher than the industry average in terms of reliability over the first 3 years of ownership.

While the BMW brand is higher than average across the board there are some models which have more problems than others.  Before purchasing a new or even used vehicle it is always advisable to research the particular model you’re interested in.  Some are built on tried and tested platforms and will be more reliable.  Other newer models such as iDrive will be new concepts that naturally will need some attention as the vehicle model develops and matures.
