How to Fix a Broken Audi A1 Engine?

I recently noticed that my Audi A1 engine is not working properly. It makes strange noises and the performance has decreased significantly. Can anyone provide some tips on how to fix it?

First, you should check the spark plugs and replace them if they are worn out. A bad spark plug can cause engine problems.

If the spark plugs are fine, then check the air filter. A clogged air filter can affect the engine performance. Clean or replace it if necessary.

Another common issue with Audi A1 engines is a faulty fuel pump. Check it and replace it if needed.
