Domrim Posted April 20, 2010 Report Share Posted April 20, 2010 hi, my name is dom, i have y reg GT TDI and i am having problems with it going into limpmode when it is driven a little harder. the car has 92,000 and i have just changed the oil and filters etc. the car runs fine, when revs reach 2000 to 2500 the car judders (like when you take a car to the limiter) and the car goes into limp mode. once the engine has been switched off and then back on again the problem disapears... until the next time. from pouring over the forums in the last two weeks since i have owned the car i have narrowed it down to.. Maf sensor, clogged inlet manifold, turbo vanes sticking on open.... all of which effect boost presure and send the car into limp mode.. could anyone help me diagnose the car further? thanks in advance Link to comment Share on other sites More sharing options...
vwsteve Posted April 21, 2010 Report Share Posted April 21, 2010 hi i think your problem will be the turbo vanes sticking you can check by seeing if the actuator lever moves freely if it is hard to move then you need to remove the turbo and strip it down to clean it hope this helps Link to comment Share on other sites More sharing options...
Domrim Posted April 21, 2010 Author Report Share Posted April 21, 2010 ah thanks. i know someone who has a lift, i presume this is easier to do from under the car? and can i just use wd 40 to clean the turbo? Link to comment Share on other sites More sharing options...
