Hello.
Is there anybody here who can give me some suggestions/help?
Have A Delphi ECU (Merc. W639 CDI).
Before fail I did a backup (plus ID) trough OBD and Kess v2.
HW: 6519020100
SW: 6519027403
Writing was interrupted (Computer failure).
No more OBD-connection possible, Kess would not write again - wrong protocol.
Opened on bench, soldered wires, got connected with Ktag,
ID was corrupted, so who knows what got corrupted? Would it only be the part written, or could other parts be affected?
Ktag would not read ECU - returned error.
So I did restore with the backup (made with OBD&Kess from before fail) on the bench, worked fine.
ECU in car, still no OBD connection possible, ignition turns on, but engine won't start, and starter not turning.
I assume getting another ECU won't help, and I assume my main problem is that I have no full backup from the ECU, only the partial trough OBD?
Is this ECU stuck in a certain mode due to the failed programming? What can I do from here?
Any chance anybody has the dataset required (ECU with updates from MB due to "Dieselgate")?
Or any suggestions how to proceed from here with the data I have?
