hi my fabia vrs seems to go like a rocket untill it hits over 3,000 revs then seems to loose power and also gose into limp mode. although once you rev her a bit or turn her off then on again she ok for a while or so any adivice ??????

great not exactly wat i wanted to hear. none of this happened untill my cambelt was changed .

It sounds like a dodgy N75 or more likely sticky VNT mechanism in the turbo, but you should get it scanned as simbo says.

hmmmmm wat exactly is an N75 and a VNT could this be caused a part of having my camblet changed as didnt have these problems untill i had it changed.

N75 is the vacuum control on the Turbo that moves the variable vanes (VNT). First check would be to get the garage that did the cambelt, to check they fitted it aligned correctly. One tooth out and it will run like a dog.

VNT and N75 can be checked by applying vacuum to the N75, and seeing if the VNT actuation lever moves freely (special tools required.)
