TCU dtc remove - Audi A8 3.7 v8 D2(4D)

[poki123]

Hi all,
I have Audi A8 D2 2000r facelift w automatic tiptronic transmission HP5 from ZF.

TCU no. 4D0 927 156 AF

Problem in this car is permanent DTC P1820 Pressure Control Valve 2 - Short to plus.
There is no real short to plus, probably TCU has internal failure. When I swap valve 1 connection line with valve 2 there is still DTC P1820 Pressure Control Valve 2 - Short to plus. No DTC code about valve 1.

Is possible to remove DTC 1820 from flash memory to prevent limp mode.
In attachment dump of flash 29F200BB from TCU

I hope you can help me solve this.
Best regards

I have 3 the same modules every one is broken in another way. But one is in virgin condition (newer opened before) with valve 2 fault also
Yes the big chip is 30349. But I have fault of valve 2 in every module.
I can open 3rd module but when I 'll swap from another that I have I think it give me fault again.
