Hi guys,
Noticed that my car has a methane/rotten egg smell from the exhaust. Not really apparent when driving forward (most of the time it's not there), but when I reverse it gets really bad (gagging bad).
I can confirm that it's not there when going forward (sometimes it is, rarely though), because I tried driving forward a meter or 2, then running to the rear of the car to see if the smell is there.
When repeating the same test but reversing instead, the smell is awful.
Does anyone else have this issue? Do you think my cat might be busted? Or could it be something else.
A bit about the car:
FN2R 2007
Kms - 75,000km
Fuel - Shell V-Power or BP ultimate
Recently bought this car second hand, and got a mechanic to check it out. The smell wasn't apparent/noticed at the time. Engine seems healthy. Any advice would be really appreciated.
Thanks in advance guys!
