Trunk Wiring problems of the 2005 Volkswagen Jetta

Left turn signal, drivers door/all remote window switches, trunk/fuel door release, drivers door lock key fob locking of drivers door/drivers door internal lock are all inoperative. Occasionally, the cabin interior light remains on with a drivers "door open" indication on the instrument cluster even though the drivers door is closed and secure (but unable to be locked from the drivers door lock switch in the passenger cabin). The primary safety issue related to this problem is that the left turn signal displays on instrument cluster, but does not activate on the rear turn signal light and drivers window (along with all other windows remotely controlled on drivers door) are inoperative if needed to make a hand turn signal or egress from the vehicle in an accident (or submerged under water for an egress). Dealer and manufacture both refused to cover the replacement cost of the faulty part. I have performed every manufacture required service required (all documented) since purchasing this vehicle in the interest of safety and reliability. It had very low mileage on my purchase in early 2007. Per vw technical service bulletin, group 09-01 (201-7600), February 26, 2009, states that the drivers door wiring harness was manufactured 80 mm too short. This results in putting strain on the numerous wires in this harness near the door boot and connector plug causing wires to break and/or electrically short. My vehicle was affected by the VIN range of this manufactures service bulletin. The new replacement drivers door electrical harness are now 80 mm longer than the originally manufactured (installed) faulty part that the manufacture is unwilling to replace at their cost (parts or labor). I will pay for my repair personally, but believe that the safety aspect of this faulty part could compromise the safety of the driver and occupants in addition to other motorist.

Windows, door locks, trunk and fuel door release and airbags non-functioning due to wiring harness located in drivers door. Found out there is issue concerning the length of the harness that causes wires to break over time.

Wiring harness between the body and the doors flexes during opening and closing of the door. The wire coating becomes brittle with age and cracks causing stress points in the wire leading to breakage of 1 or more wires in the harness leading to inoperable controls and electronics in the door, possible electrical short, and potential fire hazard. This failure tends to occur after a couple years of usage. This particular vehicle failed at 65,000 miles. Usually the driver's door fails first as it is used most frequently. This equipment includes but may not be limited to window controls, door locks, door open sensor, air bag system crash sensor, trunk release switch, fuel door release switch, door mirror adjustment, mirror turn signal indicator, mirror heating element. Wiring harness must be replaced which costs approximately $150-$200. Harness should be redesigned with longer wires to avoid stretching of the wire and wire coating material changed to avoid brittleness with age and work hardening.
