Check your OBD connector. I had same problem too.

Check that all pins in connectore well,not opened..to guarantee good contact.

VAS may do bad contact..do car start? I was unable connect some Golf5 with VAS,pins asre very short,try VAGCOM or VCDS,they have longer pins..

Ok
but i can do diagnostic for all others ecus except motor ecu
Steering wheel is very soft (same as when i reprogam ecu)
Does somebody as virgin flash and 95160 eprom dump for virginise it?
I have tested to rewrite all file with BDM but dont work
With bdm ecu can be identified correclty
Car does not start and motor fan turn high speed.

Thks

Hallo,
Have anyone fix a this problem?

[ominimicu]

how do you know the ori is ok? usually wrong checksum makes no comunication

[v8 dave]

Easiest way is to put it in boot mode and reflash using a bench harness. You need a good ori to flash back though.

A few days ago I had a similar problem. Was inserted key emulator. Diagnosing intangible Distillery ECU. Good luck in the fight
