What are the common issues with the Audi A2's engine?

I have been experiencing some problems with my Audi A2's engine. Can you tell me what are the common issues with this car model's engine and how can I prevent them?

One common issue with the Audi A2's engine is the failure of the timing belt. It is recommended to replace the timing belt every 50,000 miles or 5 years to prevent any potential damage to the engine. Also, make sure to keep up with regular maintenance and oil changes to keep the engine running smoothly.

Another common issue is the failure of the ignition coils. This can cause misfires and a decrease in engine performance. It is important to replace faulty ignition coils as soon as possible to avoid further damage to the engine.
