What are the common engine issues in Audi 80 and how can I solve them?

I recently bought a used Audi 80 and I have been experiencing some engine problems. What are the common engine issues for this model and what are some solutions or preventive measures?

One common issue in the Audi 80 is the ignition switch failure. This can be caused by dirty or worn out contacts. To avoid this, make sure to regularly clean and inspect the ignition switch. If the problem persists, it is recommended to replace the switch entirely.

Another common issue is coolant leaks, which can lead to engine overheating and damage. Regularly check your coolant levels and inspect for leaks in the system. If a leak is found, it is important to address it immediately to prevent further damage.
