Try to reprogram high speed configuration list in that ecu which gives you that code.

How to do that sir?

[kadett90]

Have you got any tester?

[wannabegtc]

I do have opcom interface with opcom software 2010 or vauxcom 2014, firmware 1.70

[kadett90]

Which ecu give you that code?

[wannabegtc]

ABS/TC/ESP ecu

Then connect to it.
Then choose programming.
There you can see program high speed CAN-bus conficuration.
There you can find configurations list....check that these match things that exist in you car.
