Those brown wires are negative for any component, connect them together to a screw motor

And black wire? Also is ground or? when I touch black with brown there is a spark so I dont think is ground. I put back black in isolation tube to avoid that. So I have 3 broken wires 2 brown and 1 black.

Browns are negative, (try to connect them), check for 12v between black and brown, in a motor vag-bjb that I have does not carry the mass point in the pump tandem, the terminals of the brown wires are not original, maybe someone change their place of mooring,
that year is the fabia? engine type?

2002 1, 9 tdi 74kw is engine ATD code, sterring is heavy when car is not moving. Also error for drive battrry voltqge I think Is present becaus one of this wires is not connected to ground and ecu detect incorect voltage. I think wires are origunal it is not replaced by some electrician. About relay fir cooling fun wheee is located ?

Hi the drive battery voltage event code is usually a bad main engine earth to engine mount or starter will look ok but corrosion forms between lead and bolt this can also cause heavy steering also water in the g250 on the rack or a break in wire from alternator blue wire or brown wire will also cause drive battery voltage event code as for the wires in the pic I'm not sure if you pm me your vin I will post some currant flow diagrams for you

The broken wire goes under plastic near air blower motor. Pls check image

This isnt original wiring from the car.

VAG wiring colors

black......ignition switch KL15

brown.....earth 31

On all wires currently has 5v between them and battery earth. Where is main earth location in engine compartment?

[makadam]

Any other help ? No one have electric diagram to check what wires goes under plastic near air blower motor

Problem was solved, wires were for auxiliary heating webasto, and problem with servo was low fluid in servo.
