If you all to do by obd2 away and yours vag k comander is clon,probably Rom flash corrupted .
I think with this dash game over.

Your dump is no Crypto and looks not bad. Open dump in normal hex editor and you will see.
I have dumps for D09 and D12 they look same.
Too see VIN and ID just swap bytes

like brend said maybe k can commander damaged Flash.

I agree, your dump file is correct

**seattm2012** · 23rd October, 2018, 02:15 PM

This file before cloning eeprom. I think it good and read by obd with can comander. But i cant write back . Maybe flash dead .but how it read and write?
Thanks.

Yes this dump no crypto because read by obd. I write other dash no crypto by programer 93c86. And now have problem. But how solved. Because this dash read and write with programer only crypto file.

Do you have a backup of epprom before doing anything or just after you killed the cluster? Then i can help you. If not then i need to have the cluster ( no way to help thru internet )
