vw touareg V10 dtc remove

[helderrr]

Hello,

I need a help, I got a vw touareg v10 in my workshop and I bought two engine units and did the immo off and the car worked. At this time the two motor units have a P1640 Control unit faulty error and would like to be able to remove this dtc from the two motor units.
Will someone delete this dtc if you please?
Attached, I send all the files of the two motor units.
The reference of the engine units is ECU EDC16U31 0281011839


Thank you very much
