What is the cause of engine vibration in an Audi 80?

I have noticed a noticeable vibration in my Audi 80 when the engine is running, especially at high speeds. What could be causing this and how can I address it?

The most common cause of engine vibration in an Audi 80 is worn engine mounts. These are rubber components that help support and dampen vibrations from the engine. It is recommended to have them inspected and replaced if necessary.

Another possible cause of engine vibration in an Audi 80 is a misfiring engine. This can be caused by faulty spark plugs, ignition coils, or fuel injectors. Have a mechanic perform a diagnostic test to pinpoint the issue.

In some cases, engine vibration in an Audi 80 can be caused by a damaged harmonic balancer. This component helps reduce engine vibrations and if damaged, can lead to excessive shaking. Have it checked and replaced if needed.
