How to calculate VW Passat MQB ELV CS code with Xhorse Multi prog?
Multi prog only reads flash data from ELV. Need to decode CS code with VVDI2 or Key Tool Plus.
You will need:
Xhorse Multi Prog programmer
MQB RH850 cable for multi prog (to read ELV flash data)
Xhorse VVDI2 or VVDI Key Tool Plus
Here is an example of calculating the CS code from VW Passat ELV.
Part no. 5K0905861
Chip: D70F3624
In Multi-prog software, select VW PASSAT ELV(5K0905861)(D70F3624)-LOCK-READ,
Check wiring diagram.
Disassemble ELV and connect ELV with multi prog via RH850 cable for multiprog
Read and save ELV flash data.
In VVDI2, go to Key Learn-> MQB Platform instrument immobilizer-> Instrument with locked NEC35xx (MQB48, VDO/JCI)-> Decode MQB ELV.
Load flash data read by multi-prog and calculate CS code.
You can also decode CS code with key tool plus via flash data.
