Default Audi A5 1.8TSI 170HP electrical schematic, wiring diagram

I have an Audi A5 1.8TSI 170HP coupe FWD, year 2008 after changing from RHD to LHD.
The electrical installation was done sloppy, lots of tangled wires.

The car had a short circuit under the dashboard, the car didn't start, there was no communication or electricity inside etc.
I fixed the electric harness under the dashboard and now the car is working properly...
lack of interior lighting - it does not work either from the button, from the remote control or after opening the door (fis shows the open door), the cluster backlight does not work too.
Of course fuses and relays are ok.

After closing the clamp for 10s (+ and -) on the disconnected battery and reconnecting the battery - the interior lighting lights up for 3s and goes out

I measured the capacitor under the hood with my meter, it charges, but the meter only showed me 3nF.
I do not know whether the meter's meter or capacitor's fault. Does anyone know the correct capacity of this capacitor?

So I am looking for a wiring diagram and description of relays for this model.
Unfortunately, I do not have autodata or elsa for that moment.

00457 - Car electrical installation controller / Bordnetz (J519)
004 - No signal / no communication

I have to first measure the wires, but in this mess it is difficult to do without a schematic.
If anyone knows on which pin what should I expected specific voltage in the roof panel lights or cable colors or drivers lock diagram.
I know that lighting is controlled by GND.

Thanks for help in advance.
