In further diagnosing fault codes 17755 and 17748 in a 2004 VW Golf R32, the Ross-Tech Wiki refers to VW Technical Bulletins 15-04-01 and 15-07-03. At one point in the Bulletin's process, using VCDS, I was able to determine that for group "209" within function 08 I found the Field 3 measurement was slightly out of the range,(-9.0 KW) specified in the bulletin. The next step reads as follows"

-Select "Guided Fault Finding"

_Select "Function/Component Selection" from the "Go to" button on navigation bar.

-Check signal function of "G28 - Engine Speed Sensor" and "G163 - Camshaft Position Sensor 2" -arrows-

-If signal functions of "G28 and G163 are OK.

-Replace upper timing chain.

My question is "How do I accomplish this process within VCDS software vs. the VAS 5051/5052 which the Technical Bulletin specifies"?

Per our phone conversation, I believe the TSB is saying to check those signals with an oscilloscope. If the G28 were truly faulty, the engine wouldn't run at all. From our experience, cam/crank correlation faults are ALMOST always a mechanical timing problem.

Thanks. I'm going to focus on the upper timing chain.
