Check engine light

The light comes from your car's onboard diagnostics (OBD-II). It can mean anything from a loose gas cap to a failing catalytic converter. Leaving it can cost fuel economy, cause misfires, damage the engine and fail an emissions test.

Ryan S.★★★★★August 2026

Had to make a quick pit stop at Erik's during a family road trip. The check engine light had come on in our BMW X5. We stopped in at Erik's with no appointment to see if they could take a quick look and diagnose the issue. They literally took the car around back before we were even in the building and took a quick look, diagnosed the issue and re-attached a hose that had worked its way loose. When we asked to pay (because we REALLY appreciated the quick service) they told us that they were happy to help and not to worry about it. You don't get service like this very often anymore. I'd recommend this shop to anyone in the Wenatchee area and anyone visiting Wenatchee. Sorry it took me a couple weeks to get this review up! Big Kudos to the the amazing team at Erik's!!

I'm new to the foreign cars and had a Christmas tree of lights on the dash. Got ahold of Erik's European and from the beginning I felt like I could trust them. Took it to them for the above and beyond diagnosis they run and he came up with the solutions to have it fixed and other preventable fixes for the future life of the vehicle. Its been 3 weeks now and not a single light has come back on the dash and the car has been running great.

Thanks Erik for the fix, you will have my business in the future and my recommendation for European Auto Repairs.

Questions

Can I ignore it for a while?

It should never be ignored. Delaying a diagnosis can lead to reduced fuel efficiency, misfires or permanent engine damage.

Can you just read the code?

We start with a full-system scan, then inspect the components the codes point to, so the repair is right the first time.

What could it be?

Anything from a loose gas cap to a failing catalytic converter. Oxygen sensors, mass airflow sensors and ignition faults are common.
