Problem:
Has anyone successfully read mqb r7f701402 golf7 2020 cluster with Xhorse multi prog? I did everything as they said. But multiprog gives error “Chip configuration failed”.
Solution:
This instrument cluster is MQB49.
Detect original key with vvdi key tool and check it is MQB48 or MQB49 key.
If it is MQB49, multi prog will not read cluster and decode immo data.
Only 5A cluster for immo data decoding
5C only for KM. Cannot do immo data.
Mqb 49 is not decoded by any machine.
User tested report: Xhorse Multi Prog cloned Jeep Compass 2021 GPEC3 ECM/ECU/PCM successfully and FC200 failed.
Select Jeep- Compass- FCA Continental GPEC3
Check boot mode wiring diagram
Connect multi prog programmer with ECM via ECU adapter. Pay attention to the boot pins.
We have backed up the original ECM eeprom and flash.
Upload original EEPROM and write to the donor ECM.
Write eeprom successfully. Then write flash to the donor ECM until completed.
GPEC3 cloning is done.
Problem:
I read JC dash from VW golf 7 cluster mcu D70F3426 with Xhorse multi prog, not possible unlock 70f3426, detection is ok but not unlock.
Solution:
Power on the Multi standard adapter to start up the programmer.
You might have this problem:
And also 12V power directly on the adapter, via connector.
Been there, found out the hard way.
Feedback:
Unlock mcu in second as said above.

I have to read a Citroen C3 1.2 Petrol ECU V56.12 but the wiring connection in Xhorse Multi Prog Boot Mode is missing.

Here is the boot mode pinout.
