[dawco998]

Hi, i need some help and advices in my car, i had accident and the plastic in which ecu is sitting was destroyed so i had to replace it, Ecu is the same. After all work done Car doesnt start, Immo light flashing on dash. I accidently disconnected ECU with battery on so maybe it has done something because before, even after accident car was starting normal, what could be wrong right now? Car opens with the key but wont start. I tried charging battery, and disconnecting it for 15min. Im also sending logs for you to check, Please some help
Best Regards

if you replaced the ecu, now you need to perform synchro
or copy immo data from the old ecu
eeprom readings are needed

Thanks for fast reply, ECU is the same, only had to disconnect it to put it in a new plastic case, but i did it while battery was connected. Kess cant recover via obd.
