Why is my Audi A7's check engine light on?

My Audi A7's check engine light has recently come on. What could be causing this and how can I fix it?

The check engine light can come on for a variety of reasons, ranging from a loose gas cap to a more serious issue with the engine. It's important to have the problem diagnosed and fixed as soon as possible to prevent further damage to your vehicle.

I had a similar issue with my Audi A7 and it turned out to be a faulty oxygen sensor. It's best to take your car to a certified mechanic who specializes in European vehicles for an accurate diagnosis and repair.

If your check engine light is flashing, it means there is a serious issue that requires immediate attention. Pull over and have your car towed to a mechanic to prevent further damage.
