Got a weird issue that started recently.
2011 Jetta TDI - Emissions update was done by VW
237,000KM
Manual Transmission, regular service is done on the car.
my scanner tool shows no codes. no engine light has ever come on.
Problem:
while driving in 3rd or 4th gear, if i slowly back off the pedal the engine rpms start going down and back up and starts causing the engine to shake.. sometimes violently. if i press slightly again the problem goes away, same if I release the pedal fully.
I have only noticed this in 3/4 gear. I have also done a test when the engine is shaking to engage the cruise control, and the behavior persists with cruise on.
RPM is usually around 1700 - 2000 when this occurs.
Anyone else out there have this same problem with their TDI, if so any recommended fixes or things to check?
I have asked the dealer but they found no fault.
