need help iv serviced my car and put a bottle of engine flush through her and the gunk went but now its cum back . how can i get rid of it
 
if you mean blackish oil, its just the oil burning because of the high temps....1.8T engines do suffer from sludge build up but regular oil changes will keep on top of it....I've wanted to use engine flush for a while but havent got the bottle incase it causes more bad than good.

If your problem is the above ^^ then its most likely expensive
 
get it checked out by all means, but I had this on my old 1.4. It's down to the car only being used for short journeys so it's the way the oil heats and cools. don't think induction kits help as mine got worse when fitted.
