Insight on oil leak on my 2005 e90 325i
I recently bought this car for a roadtrip with a friend. The car is really well maintained, but unfortunately is leaking oil. When inspected by a garage they said it propably is the rear main seal. With the covers now off I am not sure. It looks like there is a bit of oil among the oil pain seal (but not sure it really came from there). And I also found a bit at the rear of the transmission (photo 4). The oil there does not look black (the engine oil does and needed to be replaced anyway). Is my transmission leaking too? Can someone give me some insight?
