Why does my Audi A2's engine rattles when accelerating?

I've noticed that my Audi A2's engine has started to rattle when I accelerate, especially on inclines. It never used to do this before, but now it happens every time. What could be causing this and how can I fix it?

It could be an issue with your spark plugs or ignition coils. These parts can wear out over time and affect the engine's performance. I suggest bringing your car to a certified mechanic for a diagnosis and replacement if necessary.

Have you checked your transmission fluid? Low fluid levels can cause your engine to rattle and struggle while accelerating. Try adding some fluid and see if that improves the issue.

I know this might sound strange, but it could also be an issue with your exhaust system. A loose or damaged exhaust pipe can cause rattling sounds when the car is in motion. Have a mechanic inspect your exhaust to see if there are any issues.
