Can Xhorse Multi Prog Clone DQ381 MQB Gearbox?
Will Xhorse Multi Prog 1：1 clone VAG Bosch DQ381 TCU?
VAG Bosch DQ381 TCU (part number 1034420266), MCU Renesas R5F72549R (SH725xx
family), boot version bh1g0301.
From the Multi-Prog (Xhorse) connection log
in bench mode, I see:
CPU type: SH725xx
BOSCH part number:
1034420266
TCU type: TCU-2-x.x
MCU: R5F72549R (72549)
UID: E716113C /
EF722549R
Flash: 0x2800000x
Int EEPROM: 0x200000
Connection successful,
boot bh1g0301
Multi-Prog (latest update) reads internal flash, EEPROM, and
maps without issues, but the big question is: Can I do a true 1:1 clone
(including OTP/component protection/IMMO data) onto an identical donor unit, or
are there locked/OTP zones on the Renesas that prevent a perfect
copy?
Solution:
Yes if it is not MQB system.
We use the godiag gt107 with it and no
problem.
No if it’s MQB system you will not be able to clone one to one. Need
to transfer files from original to donor.
Better use MMS Flex for this. Flex will 1:1 clone DQ381 TCU.

VAG DQ381 Gen2 TCU Read Error in Xhorse Multi Prog Troubleshooting
Problem:
Xhorse Multi prog cannot read VAG DQ381 Gen2 gearbox TCU with bh1g0401 bootloader.
Multi prog says it does not support this boot version.
Connection failed.
Any idea?
Here is the clue.
Multi prog detects the boot version is 401. It is gen2 DQ381 TCU.
No tool supports Gen2 dq381.
Can’t be done yet with any tool. Gen2 protocol is not supported. Everyone is waiting.
Only few company for remap purposes, but with special procedure for unlocking the mcu.
