Audi A4 B8 airbag 8K0 959 655B transfer coding from eeprom ,coding problem

[jacob21]

Hi, I have a problem with Audi A4 B8 , car has faulty airbag module. I replace module with another one , copy CP from old to "new" and I cant change coding in "new" module.
CP is okay, there is no error now ,and VIN is ok.

Now there is 2 dtc B101100 and B101000 and MIL is ON, I cant change conding or deactivate these airbags with VCDS. When change coding VCDS says "error 22 coding rejected"

Is there possible to transfer coding from old eeprom to new eeprom ??

Are the modules same?
I would have just swapped the eeprom if they were same. What do you mean by CP?

You have encountered such a thing as Component Protection.
VCDS is not able to bypass it, you need Vag Can Pro.
Or completely clone the blocks, in which case you will not need to encode anything

When I write eeprom from old damaged module to "new" module there is errors that I cant erase ( old errors "internal fault " and "voltage to high" from past 1 year , module reject erase )

Can someone fix eeprom from old module or which part of eeprom I have to copy to have old coding ?
