Problem:
Mercedes VITO, edc16c2 ECU. Foxflash read ok via OBD, OBD Write ok but car doesn’t start.
Solution:
It was tested to work couple times so far, but maybe checksum wasn’t done with foxflash on this case. Checksum is fucked up.
If read with foxflash, power supply is important. Radiator turning on while writing.
If car does not start, read on bench, calculate checksum manually in winols/Lsuite and write in bench car start ok.
crd2 has known issues so far on MB. KESS is better on CRD2 via OBD, no problems at all.
