Mercedes A140 A/C variant coding problem

[BIOS]

Car info:

Mercedes A140 1999

ECU:
VDO MSM1.1 A 026 545 05 32
A 166 140 20 00


No trouble codes.Car starts fine.Just need to change the variant coding to A/C present.

Tried to do it with Star,but seems it can be done on a new ecu,only.Next is to make ecu virgin,or to modify the flash.


If someone has experience with this,any help is welcomed.
