What are the common problems with Audi A2 engine?

I have an Audi A2 and I've been experiencing some engine issues. What are the most common problems that I should look out for?

One common problem with Audi A2 engines is the buildup of carbon deposits in the intake valve, leading to poor performance and potentially damaging the engine. To avoid this, make sure to use high-quality fuel and get the intake valves cleaned regularly.

Another issue with Audi A2 engines is the potential for oil leaks, which can cause damage to the engine if left unchecked. Regular maintenance and checking for any signs of oil leaks can help prevent this problem.

In some cases, faulty fuel injectors can also cause problems with the Audi A2 engine. If you notice a decrease in performance or strange noises coming from the engine, it may be worth getting the fuel injectors checked and replaced if necessary.
