What are the common engine issues in an Audi 80 and how can they be addressed?

I have been experiencing some engine problems with my Audi 80 and I am not sure what could be causing them. Can someone provide some insights on the common engine issues faced by Audi 80 owners, and how they can be fixed?

The most common engine issue in Audi 80s is the failure of the coolant temperature sensor. It is essential to regularly check and replace this sensor, as it can cause overheating and potential engine damage. Furthermore, make sure to use high-quality coolant and follow the manufacturer's recommended maintenance schedule.

Another common issue is the failure of the spark plugs and ignition coils. It is crucial to replace these components when necessary, as they are responsible for starting the car and can cause misfires and poor engine performance if not functioning properly.
