[virus1976]

Good Afternoon..

This morning a friend asked me if I could resolve a problem on his passat ,which came after the mapping,which in practice has the light of the glow plugs that flashes all the time... and the hang-up appears, "engine failure".i made a diagnosis, and I have come out the following errors:

I tried to delete them the most? times but promptly reappear.

I have read the ecu and then I compared the serial written on the ecu with those read by obd. and I noticed that they are different.
Can this be the reason of these errors??
I can reset the ecu by simply typing the original file of the ecu?
It is an operation that I have to do the tour in the boot or can I do it from the obd without having to remove the ecu?
Last question mica risk of losing the code immo?
sorry for my questions from a newbie, but I have many doubts about that and I would not want to do pi? casini those who are already? been made.

thanks
