i have a golf 52 plate gt tdi 130 with remap to 170.
had the turbo reconed 2000 miles ago and has been running fine.
this week it has started going into limp mode all the time.
i have checked all the intercooler pipes and replaced a few that were worn and had movement in them.
i have replaced the turbo pressure valve aswell.
it runs better now but only if u start in 1st gear and give it death right through the gears. but say i was driving in 3rd and under 2000 revs then slowly started to accelerate the turbo would start to boost then after a few seconds would put the car back into limp mode.
i got the car plugged into a comp and it came back with with a code saying turbo pressure switch intermittent negative deviation.
i have checked all vac and boost hoses with no leaks to be found!
so any 1 have n e ideas on what could be wrong?? its driving me nuts
thanks
