Sounds very familier to my car at the moment. Exactly the same problems... I've changed the oil on my car twice in a week with no affect. Still smokes up like a good'n when i come to a stop.. But it only does it every now and then which is annoying. Doesn't smoke on startup though...
I was running mobile 1 0-40 but then changed to 5-50. The cars been running fine but the garage i took it too advised going for normal fully sync as he said it was too thin otherwise.
Still don't know if its the o-rings or the turbo's..he said just drive it until it gets worse and then well decide again...
sob sob... Craig MKIV TT 6.
