I've had my 2005 "55" reg Golf Plus 2.0 GT TDI DSG for 2 years and never had any serious problems.Couple months ago it started going into"limp mode",usually it happens at 70-80 mph,2200-2300 rpm if I put my foot down slightly,but not every time,car loses power.After I've switched ignition off and back on-It runs fine again.I've done full diagnostic a couple days ago and only fault code was 379-"Boost pressure control deviation negative".Mechanic suggested to replace boost pressure sensor-it worked ok but today,accelerating up the hill car lost power again.I do a lot of miles and car is at 125k now,it has FSH and I've done my best looking after it.This is a BKD engine famous for turbo failure-could it by sign of coked up turbo?Any advice and shared expierience will be much appreciated.
