Trunk Wiring problems of the 2004 BMW 3 Series

Vehicle adaptive xenon headlight wiring is faulty . Wire insulation is cracking/deteriorating and entire wires are breaking apart. Symptoms start with flickering xenon headlight eventually (about a week later) stops working at all. Vehicle is moving or stationary, engine on. The faulty wires are in a weather sealed compartment of the headlight and have never (to my knowledge) even been unsealed/accessed since leaving the factory. The issue is on the passenger side, unknown if it is on the driver side as well. The attached photo shows back side of the headlight housing looking down, with the weather-sealed compartment open. All exposed wire is as a result of the issue, nobody has actively cut or stripped the wires. Problem first noticed in sept of 2016, attempts were made to repair but now it has happened again, worse.
