HELP PLEASE! Newbie here, Hey all, I have a 2002 VW jetta TDI and I think my VNT actuator is stuck. Have gotten a P1556 code, Charge Pressure Negative Deviation. Going to check the N75 valve today and see it it is working correctly. All the vacuum lines appear to be ok with no holes. I tried to move the VNT actuator by hand while its still attached to the turbo in my car and can only get it to move a tinny bit and it was pretty hard to push! Any info would be great. Is it suppose to push that hard? And if it is a bad actuator how do I remove it while leaving the turbo in the car?
Thanks all.
Thanks all.
