Has there been an issue with the wiring harness going into the rear trunk lid to

What is your question?

The wiring harness has fallen apart with many wires exposed due to the wire jacket cracking. This was found due to a right rear reverse light alarm (and not working). I would imagine this is a common harness for all GTI and R32 as well as all Golf models. This is a $400+ repair expense ($210 just for harness) that should be covered by VW as this is a defective part. Please advise.
