Unfortunately, it’s a bit of a check-all warning. Lots of different things can make your Audi’s computer think something is wrong.

You just found the check engine light. Hopefully, you just saw it light up briefly during your pre-purchase examination of a new Audi. But if you see that lightning symbol turn on as you’re driving, it means it’s time to check the engine (or, really, the computer that’s registering the car’s fault codes). You might also call the light the CEL — which is just Check Engine Light shortened — or the malfunction indicator light (MIL).

Great question! We have recently polled some of our customers, and they continue to come to us because we are fair, because they trust us, because we are passionate about what we do, and because we aren’t pushy. After thinking deeply about their comments, we decided that they are right! Give us a shot, we promise to hustle hard to guarantee your satisfaction.

Most check engine lights have two settings: the first is a solid glow. That means your car has registered a problem, but it’s not immediately hazardous. You can’t ignore it, but you can probably drive your Audi safely to the shop without towing it.

A flashing CEL, on the other hand, is bad news. It means you should pull over ASAP. Check Engine Lights flash when they misfire or your car has an immediate and hazardous malfunction. We recommend you tow your vehicle to a shop instead of driving it.

It can be tempting to ignore the Check Engine Light when your Audi is handling as well as it ever has. But don’t be fooled. The Check Engine Light might be registering something that doesn’t directly interfere with its driving performance, or it might be registering the beginning of a serious problem that will develop into an expensive headache if you let it. If your CEL is on but the car feels fine, all that means is that you can safely drive the vehicle to Bluewater instead of having it towed.

No. You’ll see a different indicator light up every 7-10k miles to remind you to get an oil change.

Check Engine Lights don’t notice every problem. That includes physical issues (like with brakes). If your brake is hard to push down, it’s stiff, or the brakes are squeaking at the same time your CEL turns on, your car probably has two different problems. Call us and schedule an appointment to get both problems looked at.

Whenever there’s a serious problem with your car’s handling, our mechanics can advise you on whether you should drive it yourself or have it towed.

Yes. If you start driving away with the gas cap off, your CEL will turn on to alert you. If you catch it quickly enough, there shouldn’t be any serious problems. Bring it by and we can clear out the fault codes, so you don’t have to stare at that light. We can also check the codes to make sure everything is still operating smoothly.

No. A lit CEL will make your car fail. Bring it by our shop so we can check the codes and get your car in passing condition.

The only way to pass emissions in Denver, Colorado, is to have a car that’s running right. Schedule an appointment with our experts at Bluewater Performance, and we’ll let you know what your Audi needs.

You found the brake pad indicator light. It uses a sensor to detect when your pads are nearly worn through. It may not be an emergency, but it’s definitely time to get your brakes replaced.
