Why does my Audi A6 produce a burning smell while driving?

I recently noticed a strong burning smell coming from my Audi A6 while driving. It seems to be coming from the engine or exhaust area and happens more frequently during acceleration. I've checked the oil level and it's fine, what could be causing this issue?

It is likely that your car's catalytic converter is overheating and causing the burning smell. This can be caused by a faulty oxygen sensor or a clogged catalytic converter. I recommend taking your car to a mechanic to have it checked and replaced if necessary.

Another possible cause could be a leak in your car's fuel system. The smell could be from fuel vapors leaking under the hood. I suggest checking for any visible leaks and getting it fixed promptly.
