Why is my Audi A6 producing a strange smell?

I have noticed that my Audi A6 has been producing a strange smell lately. It seems to be coming from the engine, but I can't pinpoint the source. What could be causing this and what should I do about it?

It is possible that there could be a leak in your engine or exhaust system, causing the strange smell. You should bring your Audi to a mechanic as soon as possible for a proper diagnosis and repair.

Check your air filters and make sure they are clean and functioning properly. A dirty or clogged air filter can cause unusual odors in your car.

You may also want to check your cabin air filter, as it could be the source of the odd smell. If it is dirty or damaged, replace it to improve the air quality in your Audi.
