So I tried pulling some DTC's yesterday... I'm rather new to VCDS (picked up my first cable and software a few months ago) and I'm not 100% sure which block to check out. I've tried all the ones that sound like it could be linked to the a/c, and so far most of them have said '' cannot communicate with controller '' or something like that. I will be fiddling around with some of the wiring. I know that I have spliced the wires that are color matched:
Black and Yellow and Black and Grey are spliced from BHW harness ---> Audi harness.
4. gn/bl (green/blue) going from A2 to the ecu. This appears to be the engine speed signal.
Perhaps if I spliced this one into the passat's rpm signal??? Which pin could that be on the T90 connector?
