I have noticed today that there is (what appears to be water) leaking from the backbox. Is this normal only as only had the car 4 months Thought would be appreciated before I go to the dealer!
Possibly just condensation that's not been burned off due to Exaust not getting hot enough to evaporate it .. As it gets colder u notice it more when cars pull away from Jounctions ect ...
I see in one of your photographs there is a drain hole. This as one would expect is there to allow drainage of water as the system heats up. Prevents the rusting of the box from the inside, that was a common problem many years ago.
