Why is my Audi A5's Check Engine Light On?

I recently purchased an Audi A5 and the Check Engine Light just turned on. What could be causing this and what should I do about it?

The Check Engine Light could come on for a variety of reasons, including a loose gas cap, faulty oxygen sensor, or malfunctioning catalytic converter. I suggest getting it checked by a mechanic as soon as possible to prevent any potential damage to your car.

Don't panic, but don't ignore it either. The Check Engine Light could indicate a minor issue or a more serious problem. I recommend taking your car to a trusted mechanic to diagnose the issue and make any necessary repairs.
