I have this ECU: 4A0 907 401 E, 0 281 001 254.
I read the eproms and check chksum in ECM titanium. Program finds 2 drivers, 1 for 1.9TDi and one for 2.5TDi.
Interesting, because chksum from eproms match for the 1.9TDi drivers both. Anyway, my problem is the starting very bad even cold engine not only hot. I think injection pump is well calibrated but is very noisy.
Uploaded dumps, Can somebody check me for it?
