Audi Check Engine Light

Why is the check engine light on in my Audi? How do I fix it?

The check engine light can come on for a variety of reasons, including a faulty oxygen sensor or a loose gas cap. It's important to get it checked out by a mechanic as soon as possible to prevent any further damage to your car.

Make sure to check your gas cap first, as a loose gas cap can often trigger the check engine light. If that doesn't solve the issue, take your Audi to a trusted mechanic to get it properly diagnosed and fixed.
