Problem:
OBDSTAR DC706 and MP001 renewed (virginized) Mercedes Benz FBS4 VGS4-0-NAG2 4-4 gearbox TCU ok. But cannot learn with Xentry. Authorization failed (TCM not clean!)
Here is the clue.
If you don’t have the original unit to transfer data then virgin option is useless because xentry online will refuse it because this exacly unit is assignet to different vin already on server!
You cannot use a used fbs4 part it saves the chip ID which cannot be changed and if that chip ID doesn’t match your car or is in their system as belongs to another vehicle it will flag it and not let u program it all the chip ID that can be learned with xentry have to be in their system as new.
Not possible to adapt Virgin fbs4 units online, only clone immodata.
You can program used security parts with Xentry Online. Clone or use Arbitres.
