i bought the car used and im having this bad smell after it rains. this is the second time it had appeared. i spray the carpet with lysol but im not sure it is working. when standing outside you can smell the car. the smell is like a wet dog. my car is a 2012 cls550. i changed the cabin filter already.

I found out where the smell is coming from. It is the front airmatic. How to fix??
