bit of a wierd problem, i was driving down the motorway yesterday night and i seem to have lost some power! cant figure it out!!! still pulls well, no oil leaking, all gauges normal ect but a loss of power! its quite annoying! any ideas?????

i am thinking either boost leak from somewhere, (have looked but cant see anything!) or maybe a manifold or exhaust gasket??? it seems a little loud but i cant remember if it was like that already lol!!!

someone did suggest a sticky n75 valve but after searching im thinking thats only on Cupra's and not my TDi!!!

Any help greatly appreciated!!!
 
a little update! before this hapened i used to hear a relay clicking under acceleration, i cant hear this anymore so maybe this is my problem??? anybody know what a relay could be used for which would work under acceleration??? sorry for the jibberish lol!
 
Got a VAG COM code!!!

17958, charge pressure, control deviation!! this should be either, N75 valve, split vac hose, popped off boost pipe or sticky vanes. hope to god its not the vanes!!!! turbo was new on 2000 miles ago!!!!!

i have had the EGR blocked off, so could i use the old EGR controller thats not connected in place of the N75 or is this only good temporarily???

Any help appreciated!!!!!
