OK, we are at our wits end!! There has been an on going deterioration of power over the past couple of years with our 2001 TDI. It has been in the shop, (Aaron's Autowerks of Phoenix Oregon) more than several times and we have spent literally thousands of dollars to no avail. Today we returned from a road trip where it accelerates well up to around 2500 RPM but then bogs down. We are just creeping over the hills at 45 MPH and shifting down where before just leaving it in fifth gear and cruise control would have sufficed. No CEL. Items that have been changed:
N75 and N18 valves
vacuum hoses
MAF
Turbocharger
Fuel Filter
Fuel injection timing adjusted
Shop says:
Compression is good
Intake manifold is not clogged
Injectors checked and good
catalytic converter is not clogged
Fuel tank pickup clear
Any other helpful suggestions would be greatly appreciated!
