Since having my S-Tronic, Haldex and rear diff oil changed a couple of weeks ago every time I put my foot down the car smells of a really strange oil smell. More pungant than just engine oil. Doesn't smell whilst driving normally. I thought maybe there was some excess oil from spillage just burning off but it's still there just as bad. Also now when cold and setting off the car seems to engage gear then disengage then engage and then be fine. On a rolling start it's fine just when I release the foot brake e.g traffic lights. Any suggestions?? Thanks, Nick.
