Quick question on coding please

I recently fully retrofitted power fold mirrors to my 2019 Leon ST with power mirrors and door controllers sourced from the same 2019 donor vehicle.

Everything works absolutely fine, with the mirrors folding and unfolding without issue on both the mirror control switch and when locking/unlocking the car with the keyfob.

However, a recurrent fault keeps cropping up on VCDS - Drivers door module 42, 196726 Motor for mirror fold in - open circuit - intermittent

If the mirrors are folded with the switch and a new autoscan is done, no fault is thrown up, but it's when the mirrors are UNFOLDED with either the switch or by unlocking the car that the fault shows immediately and every time. All wiring has been checked and re-checked.

I've searched and searched on VAG forums and on Ross Tech's website, and can't find much anything other than it seems many folk having done this retrofit find the same issue on VCDS autoscans.

Screenshot of the fault attached

As said, everything is working fine, but my OCD is in overdrive! Really want to resolve this if I can.

Many thanks

Intermittent errors like this one (or short to ground) are caused by either motor being stuck, or a poor connection somewhere. the door control unit measures the motor during its operation, if the current going through is out of range in either direction, it will throw. Chances are the motors from donor have their best years already passed. If everything works, I'd suggest you live with it as it is until it stops working. Most of the parts such as this one are waterproofed and sealed shut, with no way to disassemble - spraying WD40 all over it often don't have any effect and attempts to disassemble and get the grease where it needs to be often ends up with an order of a new part :)

I've tried lubing seizing locks many times for many folks, ultimately the new locks were ordered anyway within a month or two.

Also the switch might be faulty
