Ok my first post here, galaxy 2004 1.9 tdi 115 BHP auto, the problem I have is this, loss of power when accelerating can happen at any speed or revs [limp mode]have had a few garages have a test run the answers differ somewhat, over-boost, under-boost? Can someone confirm that if the power to the MAF sensor is disconnected that if it then runs better that the MAF is at fault? :P
