fitted my rs3 grill today, however when disconnecting the parking sensors in the grill, one of the wires appeared to be corroded and has sheared off, so now my parking sensors aren't working, does anybody know if it's possible to buy either the loom behind the front bumper or preferably just the plug with a bit of wiring on so I can splice into the loom? It's broken off too close to the plug for me to do this already
