Audi Check Engine Light Diagnostics and Repair in Walnut Creek, CA

It’s normal to have anxiety when the check engine light comes on, but you can rest assured when you put your Audi in our hands, there won’t be a problem for long. With our world-class diagnostics technology, we’ll pinpoint the cause in no-time. Our technicians are certified by the National Institute for Automotive Service Excellence (ASE) and we provide them with state-of-the-art digital diagnostic tools.

The check engine light can come “on” for a wide variety of reasons – there are literally hundreds of conditions that can cause it to be illuminated. From something as simple as a gas cap that no longer holds the pressure, to engine issues, spark plugs, sensor problems (oxygen sensor, mass airflow sensor), vacuum leak, even catalytic converter failure – any one of them will cause your Audi to illuminate the check engine light.

When the check engine light is flashing, this indicates condition that could result in engine damage, so we recommend pulling over in a safe spot, turning off the engine, and having your Audi towed to a repair shop.

Keep in mind that these aren’t the only culprits that might be behind the check engine light. Even if it is not flashing, we highly recommend you bring your Audi for a checkup – driving with the check engine light unresolved can cause expensive damage.

At Diablo Auto Specialists in Walnut Creek we can offer convenient appointments, complimentary local Uber/Lyft, and 36 months / 36,000 mile warranty on all repairs – so when your Audi turns on the check engine light, bring it to our car care facility. Our friendly service advisors will answer any questions you may have, and we will get your vehicle fixed, usually the same day.
