BMW 2011 335i coupe hissing noise exhaust
Recently I purchases a 2011 BMW 335i coupe and during the idle....I notice a low
hissing noise coming from my rear left exhaust. Is this normal or any guess why it
would do this? The car is under warranty but before I bring it in I like to pin point the
issue so they don't give me the run around. Any one experienced something similar?
Thank you all.
