This is an old Bentley, a flood car. Here we will show how to get this immobilizer clone so that we can finally start it up.
The KESSY Module out of a Bentley. The drowned one needs to be cloned. The cloning is for KESSY.
We have the original drowned one and another KESSY module from junkyard.
Here shows how to clone the KESSY module using Xhorse Multi Prog programmer.
Run Multiprog software, select VW-KESSY Backup read & write (2008-) (WLED)
Check wiring diagram.
Make a strong zoom-in, every point must be welded on it.
Make sure everything is connected to the wiring diagram.
Read eeprom data.
Verify data.
and save original KESSY eeprom file.
Disconnect wires on the original KESSY module.
This is a donor KESSY module.
Connect junkyard KESSY module with xhorse multi prog and mcu adapter following the same wiring diagrm.
Backup the eeprom of the donor KESSY module.
Open original KESSY data and write to the junkyard module.
Write original backup data successfully.
Read KESSY module data again.
Make a comparison between the new KESSY data and original KESSY data.
The two files being compared are the same.
So the KESSY module is cloned by xhorse multi prog successfully.
