Everything You Need To Know About Check Engine Light Diagnosis For Your BMW, Service & Repair. With A Free Check Engine Light Code Read Offer!

One of the most confusing lights on your dashboard cluster is “The Check Engine Light”. When that light turns on it does not give you any real idea of what’s happening.

It’s as if you got a letter in the mail from your doctor saying, you’re sick. It could be anything… just wanted to let you know. Yep, it’s that vague and frustrating because it causes us so much worry!

So first take a deep breath, yes it’s true it could be something big like an expensive catalytic converter replacement or it could be something as simple as a loose gas cap. The great news is it’s much more likely to be a loose gas cap.

So first thing first, screw on that gas cap and turn your car on and off a few times and see if that fixes the problem. If it does, Great! However, the code will likely still be stored in the computer. If you are due for emissions testing soon, see us first to make sure the problem is resolved.

If you don’t want to do the gas cap check and want us to check it out. Give us a call, we will set up a time for you to come in. We will use our scan tool to pull up the code for free and get an idea of what the issue is.

What Your Check Engine Light Truly Means:

Ok, let’s get a little geeky. The check engine light is part of the onboard diagnostics or OBD-II system and every problem it detects basically means something is wrong with the emissions system.

Yep, I know it seems goofy, why does a check engine light diagnostic computer only monitor your emissions system? Well first, it’s better for the environment to have every car running cleaner, so every car has a computer for that purpose.

Second, most issues with your engine will show up in the emissions system.

As an example

Let’s say a hose that carries fuel to your engine has a leak. Well, the onboard diagnostics will say hmmm… it looks like the BMW engine is not getting enough fuel, which affects the emissions system. So it will turn on the check engine light and present a code that says.

“Your engine is not getting enough fuel”

It is very common to think that if the computer displays a code it’s telling us exactly what’s wrong with the car. Like, replace this part.

However, the computer is not that smart yet. In this example, it can’t tell why there is not enough fuel getting to the engine, only that the computer in the engine is reading. “NOT ENOUGH FUEL.”

Why Should You Have An Experienced ASE Mechanic Diagnosed Your Vehicle?

This is where an experienced ASE certified mechanic & BMW shop comes in. You see if we get a code that says. “Your engine is not getting enough fuel” between our software and experience we know there are probably 30 reasons why that problem is happening.
