Tried to adjust the IP pump timing on fellow TDiclub'r Munly who has a 2002 ALH. VCDS said that the timing was retarded at a value of 38 using the TDI timing graph in the latest VCDS app.
Adjusted the pump by loosening the 3 bolts on the gear and turning the pump clockwise. Went back and checked and the reported value was still 38. Tried moving the bolt again a bit more clockwise and value stayed at 38.
Tried turning the bolt counterclockwise and checked again and still 38. Tried a bigger bump clockwise and still 38. 4 different IP gear adjustments and all with the same reading.
No apparent issues otherwise but Munly says that fuel economy hasn't been the best. No check engine light was on.
Recent and only upgrades are .216 nozzles and a stage 3 tune from Malone. as well as a race pipe and EGR delete.
The car seems to run fine with good power but the lack of knowing where the IP timing concerns us.
The original thread which talked about issues Munly had with the nozzles can be found here. I don't see any reason why the tune or nozzles would effect the IP timing readings.
