Summary of change:
'''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. ** www.vems.hu/download/v3/doc/assembly/v3_mainboard_resetChips_variants.pdf * ''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. ----
