Over the last few days my car has started going into "limp mode". This morning i was entering the motorway and was in a bit of a rush so i put my foot down in 5th gear, i was only doing about 50-65 and about 2-3.5 RPM and the car just lost all power as if it had cut the turbo off. For the rest of the journey it just felt really flat and lifeless, as though it had no turbo. It also did it a few nights ago this time in 4th gear accelerating hard up to about 40ish again at relatively low RPM. It seems to do it when i accelerate hard in the higher gears. Now each time there has been no warning lights at all? I don't have access to VCDS unfortunately. Any help or ideas would be gladly appreciated, cheers.
