Hello, need help with Audi a6 BCM2 2011.
4H0907064bn

My friend was trying to update bcm2 with ODIS but he accidentally interrupted an update. So now BCM2 is not answering on diagnose and there is no ignition. He was trying to do update again but ODIS wont do that. I am not familiar with VAG group, so need assistance.

I read D-flash and P-flash with vvdiprog. VVDI2 in BCM2 dump tool show VIN , CS and other data, so I am not sure what is the problem.

Could some one inspect this dump files if thay are corrupted and maybe fix them.


Also I was trying to load someones dump from the same BCM2 but with the same result (no diagnostic and ignition),
I assume that I can not simply load another dump as it is probbuly related to processor ic serial. So probbably best option is to fix my original files.
