I've just brough a A3 2.0TDi Quattro, really impressed so far , But while having a look around the engine bay i've found an oil leak !! What I want to know is where is this leaking from & is it a serious problem? The area of oil leak is on the left hand side, just around the black vacum unit & between the cam belt cover & leaking onto the alternator housing.
Any advice would be really helpfull
