have a '51 plate golf 1.8t gti that is totally lacking in any turbo power and smokes like a train!! Turbo can still be heard spinning but misses the punch. have taken advice from few mech's and checked(as far as can see) all hoses, finding only the rocker breather split, replaced and still same problem. any other ideas from you guys,is this a common problem with a simple solution or am i faced with a huge bill for turbo replacement.? please help as funds a bit low due to baby on way.:aargh4:
