How do I troubleshoot a malfunctioning Audi A7 engine?

I have been experiencing issues with my Audi A7's engine and need some guidance on how to troubleshoot it. The check engine light is constantly on and the car is overheating. How can I diagnose the problem and fix it?

First, check your engine coolant levels and make sure they are at the appropriate level. If they are low, top up the coolant and see if the issue persists. Next, consider checking the thermostat and radiator for any clogs or damages. If those are all fine, it could be an issue with the fuel system or engine sensors.

It sounds like you may have a faulty thermostat in your Audi A7. This can cause issues with your engine's temperature regulation. It's best to take your car to a certified mechanic to have it checked and replaced if necessary.

If you recently had your Audi A7 serviced, it's possible that something was not properly reconnected or calibrated. Check with your mechanic to make sure all connections are secure and that the car has been properly tuned.
