If it is carbon build up I will see it next weekend when I pull it apart to put the injectors in and do my valve cover gaskets. However, carbon on the sensors typically leads to an implausible signal from the pressure sensing glow plugs. Yes the ecm is on the latest software released from VW.
I haven’t been able to beat what my parts guy can get them for the new ones from vw so far.
As for value blocks
injector set point 1, 2 and 3 for each injector is what you look at to determine your injectors. Each set point has its own value block for each injector. I can give the uds addresses tomorrow if you want the uds numbers, they are easily searched out with VagCom but that is the block definitions. I will list what my readings are below for information purposes.
Injector 1 2.35 -.4 -2.0
Injector 2 -3.05 -4.0 -4.8
Injector 3 6.0 -.8 -2.0
Injector 4 36.6 .4 .8
Injector 5 6.0 -3.6 2.0
Injector 6 13.4 -3.6 -1.2
interestingly enough, those data blocks where only giving me faults for 3 and 6. If I continued to drive it after doing my resets, I am sure I would get a fault for cylinder 2 and cylinder 4 as it’s constantly pulling to adjust that injector quantity for cylinder 2 and it was massively adding for cylinder 4.
