How to troubleshoot a faulty engine in the Audi A1?

I've been having issues with my Audi A1's engine lately, and I'm not sure what's causing it. The engine often stalls when I'm driving at low speeds, and it also makes strange noises. Any advice on how to fix this issue?

It sounds like your engine might be having fuel delivery problems. Have you checked your fuel filter and pump? These are common culprits for engine stalling and strange noises. Another possibility is a clogged air filter. I suggest checking these components and cleaning or replacing them if necessary.

Another potential cause for your engine troubles could be a faulty spark plug or ignition coil. These are responsible for igniting the fuel in the engine and can cause stalling and engine noise when not functioning properly. I recommend having these components checked and replaced if needed.
