Why is my Audi 80's engine making weird noises?

I recently purchased an Audi 80 and noticed that the engine makes odd noises when accelerating. It almost sounds like rattling or grinding. Could this be a sign of a bigger issue?

It's possible that the engine noise could be caused by a loose belt or low oil pressure. I recommend taking your car to a certified mechanic to have it checked out.

I had a similar issue with my Audi 80, and it turned out to be a faulty spark plug. Get your spark plugs replaced and see if that resolves the noise problem.

Based on my experience, engine noise can also be caused by a clogged air filter. Check your air filter and replace it if necessary. It's an easy and affordable fix.
