Hello All,
I am new to this site. Lots of helpful info. I have a 2005 Jetta Wagon tdi with turbo issues. It has no power on hills(down to 50km/hr or 30mph on steep grades), max speed on flats is 100km/hr or 60mph and when I kick down it over revs (stays in 3rd until I release the pedal). I am getting 2 trouble codes, p0234 turbo overboost condition and p2564 turbo boost control sensor A circuit low. The actuator on the turbo moves freely by hand and I can see it move when the car is started so I'm assuming no vacuum issues. I switched out the n75 control valve with the egr valve as a test (no improvement). Is there any other solenoids to check? Any Ideas would be greatly appreciated. I'm stumped!
Thanks
