I read this day's some topics here and it's clear...the control unit is not that easy to work on. I started to repair the cruise control units from old Mercedes, like w123, w126, R107..., and it's not that complicated. I even built a bench test to check the functionality and it's working very well.
Inside the amplifier (control unit) some capacitors are dry and is easy to be changed, some soldering to motherboard and it's ready.
I tried to open the roof control unit from Audi and ... all components are newer, smaller and with higher complexity. Nothing to do.... I tried to soldering all connection from the circuit, but without any result.
Is not that easy like I thought, but I'm sure that if someone with more knowledge in electronics will dedicate a little more time, can easily repair this control unit. At the end, being so many from old generations (without A), I suppose that the problem is has to be the same for all. Definitely is some cheap electronic parts for which the costs is a few euros.
I have some non functional control unit and I will try to change some components. I will post here if I have some good results.
best regards
