Yanhua Mini ACDP Failed to Clone VAG DQ381 401 Bootloader?

Problem 1:

I’ve tried to correct the mileage on a DQ381 with Yanhua ACDP 2, but it comes up with an error (write routine data error). It ID’s it fine

Problem 2: 

Trying to clone VW DQ381 gearbox with Yanhua Mini ACDP2 but no luck.
When writing data, it says downloading routine data error.

Here comes the solution.

In the cloning menu, detect gearbox system information.

Check the BOOT version. If the boot version is 401, new boot ver 0401. Bench no works. Yanhua ACDP will not clone this gearbox nor correct mileage.

DQ381 G2 401 bootloader is locked. ACDP cannot do it.

As DQ500 and DQ381 gen2 have same mechatronic both have the new 401 bootloader and are bench locked.
