I have got VAG com share ware version that I am upgrading to the full version. I am just waiting for the validation code from Ross tech
My car is the AUDI A4 AVANT 1.9 tdi AJM 2000 X reg
I have a fault 17964 charge pressure negative deviation
Can someone please guide me through the tests or proceadures that I need to follow so that I can pinpoint the fault that is causing my power loss.
So far I have replaced all the vacuum hoses and checked the boost pipes for leaks. I have also cleaned the turbo with innotec and the vnt actuator rod is moving freely. I have replaced the MAP sensor.
I desperatly need some guidance on the use of VAG com and what it is telling me, so as to help me identify the fault
I can only assume that a sensor or valve is faulty but I may of missed something.
Any help would be much appreciated. Thanks in advance.
