2001 TDI Just bought and now it surges when going with moderate pedal. It will have good power until about 3/4 of intended RPM's. Then the power just falls off. Trans seems ok and engine mechanically ok (as far as I know). I did find out that the EGR valve has a diaphram vacume leak. The previous owner pluged the vacumme line to the EGR and put a reisitor on the mass air flow sensor to fool the dash light code that it was still operational. Now I need some thing else to look at. Next thing I think to test is the vacumme to the turbo to see if it drops power when the turbo gets a signal. What do you think or have experienced.
