Where has the wiring harness been cut; if you can take a photo, please post it up. As with most wiring; you could reconnect the break with solderless butt connectors. If you need to replace the connectors, plug to the sensor, the sensor itself or part of wiring; your VW dealer, sells the needed replacement parts you need. Please, post a photo of the damage and tell us more, about the nature of the needed wiring harness repair. Thanks.
can not get a pic but the plug is brown with clips on side with little wire on ends. where do these 2 wires go up in the engine. Could the whole thing be replaced. I have no clue how to splice wires... maybe this pic will work
