What are some common issues with the ignition system in an Audi 80?

I recently purchased a used Audi 80 and I'm having trouble starting it. It sometimes takes multiple attempts to start the engine and the car shakes when idling. What could be causing these problems and how can I fix them?

The most common issue with the ignition system in an Audi 80 is a faulty ignition coil. This can cause difficulty starting the engine and shaking at idle. I suggest getting your ignition coil checked and replaced if needed.
