It’s a Geely Coolray 2024. The owner needed to slightly adjust the mileage to maintain the dealership’s warranty (they had adjusted it before the maintenance).
The panel looks like this.
First, remove the instrument panel. To do this, pull the visor up with one sharp movement, unscrew the 12 screws, and then remove the panel. The rear panel cover is secured with clips and 4 screws.
EEPROM chip which contains the mileage.
He read the m24c08 microcircuit using Xhorse Multi prog programmer, but it’s necessary to desolder it; you can make a mess with a clothespin.
Let’s remove the dash panel, lower the fuse box, and unscrew the four BCM mounting bolts. It’s on the left pillar at the top of the front; it contains a bunch of components. Removing it is very inconvenient. Next, we need to find something to read it with. There’s no EEPROM there; all the information is stored in the processor. The MultiProg programmer from Xhorse helped us with this. The connection is easy, but you’ll need to be handy with a soldering iron.
He read it, sent it to the same programmer, uploaded it back to the BCM, and then re-entered it into the instrument cluster.
He put it back together, and bingo! The mileage is exactly what he needed. He ran the auto launcher through the modules, and the transmission included the mileage from the BCM.
Here comes a customer review of cloning/replacing a 2017 Skoda Octavia III MQB dashboard using Xhorse Multi Prog.
He recently purchased this dashboard.
Cluster part number: 5E0920750E.
He read the data from the old dashboard, including mileage, VIN and so on.
Then he read the data from the new dashboard and transferred it.
After transferring all the data from the old dashboard to the new one, he installed it in the car.
Everything was done using Xhorse Multi Prog programmer. When he updated the immobilizer data, everything transferred, including the VIN information, all the codes, and the key information.
So, the long-awaited dashboard finally accepted the keys. Just need to fix a couple of errors and it’s ready.
Xhorse VVDI Key Tool Plus and VVDI MLB Tool for the win.
Added a new smart key to the Bentley Bentayga 2018 successfully.
Disassembled the original key and read data with MLB Tool.
Generate dealer key and learn key with VVDI key tool plus.
No SFD gateway.
Problem:
Xhorse Multi Prog failed to read Renault/Dacia EMS3125 ECU. After connecting, the program reads the processor identification but does not read the content. The software reported a chip data reading failed error.
Solution:
As the multiprog said, the chip is encrypted and cannot be read.
The processor is password-protected.
Xhorse multiprog cannot read this; boot mode only combiloader, obdstar or trasdata.
Here comes the user review of GM BCM cloning using Xhorse Multi Prog programmer.
First attempt:
BCM GM with 24c32 RH850 R7F701053
I problem with this BCM water damaged same parts numbers, so i clone eeprom 24C32 but i have all functions working
like door lock from driver\passenger side no work, driver windows no work.
Is it possible to clone RH850 R7F701053 written only CFLASH *multiprog*?
if we can clone this MCU/BCM safely without damaging the MCU?
Second Attempt:
Need to write eeprom and flash together.
DFLSH is all FF FF FF.
Cflashhave content.
Solved, only need eeprom and cflash job done.
