Hello, bought audi a3 8p with issue, the power windows and sunroof sometimes works, sometimes not, if one of them works, then everything working too.

Checked all fuses, seems all fuses good, checked doors wires, they are good, from computer windows regulator works, from switch not working. Power windows switch has the power.
Most of cases if the power windows does not work, i have to turn off ignition and turn it on again and it works again for some time, then stop working and i have to repeat that if i want to get it working. Did a error scan, there is one scan related with power windows motor:


Any ideas?
