Hello,
I just monitored the injection timing of my 2.5 V6 TDI engine (AKE)
When I look in measurement block 4 of the engine ECU (using the 5052) I see engine rpm in field 1, an injection angle which changes with rpm and load (from 2° atdc to 12°btdc) in field 2, field 3 stays fixed at 0.0 btdc, field 4 shows a percentage which varies with load and rpm.
Am I correct in assuming field 2 shows the requested injection timing and field 3 the actual injection timing ? If this is te case there is something wrong.
I now my needle lift sensor is faulty, it gives an error code in the ECU (shorted to +, permanent error, I can't erase it). Could this be the cause ?
Best regards
Stefan
