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.

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.
