Problems with the Audi A1 engine

I've been experiencing some issues with the engine of my Audi A1. Whenever I accelerate, there's a strange noise coming from the engine and the car's performance seems to be affected. What could be causing this and how can I resolve it?

It sounds like there could be an issue with the engine's components or possibly a clogged filter. I would recommend taking your Audi A1 to a certified mechanic for a thorough diagnostic check to determine the root of the problem.

It's possible that the problem is related to the engine's spark plugs. Have you had them replaced recently? If not, I would suggest getting them changed as they can cause issues with engine performance if they are worn out.

Based on the symptoms you described, it could also be an issue with the fuel system. I would advise taking your Audi A1 to a reputable dealership, as they have specialized equipment to properly diagnose and address any fuel system problems.
