ECUs sent in for repair 2017
All of the ECUs listed below will not be used in the projects they came from. I've replaced the ECUs already and fixed any/all issues that caused the problems.
Check function of the boards and report back any issues, or return to me if healthy after quick fix.
I authorize mainboard replacement if necessary in all cases.
3399
- Stepper chip removed by customer after short in the coil harness (heat radiation).
- PCB damaged around stepper chip, do not replace chip - just leave as is.
4153
- No lambda sensor signal after water came into lambda sensor connector.
4254
- No lambda sensor signal after water came into lambda sensor connector.
4770
- No lambda sensor signal after water came into lambda sensor connector.
- Replaced by 17319 IGBT 2+6, LCD, Knock, 1xEGT, VR+Hall, 400 kPa
8098
- Outputs shorted to power in standard BMW M50 harness (heat melted wires).
- I removed one injector FET and one ignition IGBT that had shorted.
- There could be more damages.
- Replaced by 14365 2xEGT, VR+Hall, 400 kPa
10115
- ECU has never been used, only test bench.
- It has the bootup/reset problem. I tried the simple fixes with components sent by Marcel but it did not help.

- Replaced by 18357 LCD, Knock, EGTx2, Hall+Hall
11820
- Stepper output shorted to +12V in harness (yes resistor in series now in place).
- Symptom is a 250 mA current draw, no VR trigger, possibly damaged P259.
- Replaced by 17039 LCD, Knock, 1xEGT, VR+Hall, 400 kPa, SD Card removeable
14821
- Same as 11820
- Stepper output shorted to +12V in harness (yes resistor in series now in place).
- Symptom is 250 mA current draw, no VR trigger, possibly damaged P259.
