Here comes the 2 working solutions to common Xhorse Audi BCM2 adapter data reading and writing problems using VVDI Key Tool Plus or VVDI Prog.
- Unknown error 130400.1
- Writing service mode data to 99%, write failed
- Solution to “unknown error: 130400.1”
Read DATA1 success, reading DATA2 got “unknown error: 130400.1” error when progress goes to 2% it says “the data reading failed” with vvdi key tool plus.
How to fix?
Proceed with caution when you get “unknown error: 130400.1”. just check if the wiring or the adapter has stable contact and if the external power supply is stable, again try 1-2 data reading until successfully (do not read DATA1 again during this process, or do not try to unlock and try to install back to the car). After the data reading is normal, there will be no other problems, and then you can install back to the car.

- Solution to the writing service mode data to 99%
Read both DATA1 and DATA2 data successfully, the IMMO data and service mode data are generated successfully. However, vvdi prog reports an error when writing service mode data to 99%, after trying again, the system pops up that the erasure failed. After that try to read DATA1 again, it will not be able to read.
How to fix?
If you have the same problem that the DATA1 and DATA2 data is read successfully, also the service mode data is saved, then just select the unlock option to unlock the CPU.
Wait until the system says that the unlock is successful.
At this time, choose the service mode, then import and write the service data.
After the data is written successfully, just install back to the Audi car, and the vehicle can work, you do not need to do any processing.
