I drove to a friends house and about two hours later got in the car and started to drive then 10 of my exterior lights all went out the same time. My footwell lights I cannot dim or brighten through the controls and back up sensor stopped working. I had no headlights while I was driving at night at around 11pm. All this happened at once at the same time. All of the bulbs were fine. I replaced them. They weren't even blown. Fuses were fine. This is a real safety hazard and can lead to crash if not looked into.
2010 Volkswagen Tiguan. Consumer writes in regards to headlights not being aligned.
Warning message "check front left headlight". Tested the light and it was not working. Purchased a new bulb, replaced the bulb and the new bulb was not working. Tested the bulb and it was good. Opened the fuse box under the hood and noticed the 30 amp fuse (top left corner of box) was burned/melted. Attempted to remove and was unable to remove. In addition the corresponding 15 amp fuse was burned out but not melted. Contacted the dealership and was informed that my particular vehicle was not involved in the NHTSA investigation for faulty fuse box. Researched further and discovered that Tiguan models from 09-12 were under investigation. In addition to the front headlight I also replaced the right rear light which was also out. I did not test the existing bulb on this light. Just replaced. I would like for this to service a formal complaint to the NHTSA regarding what appears to me as an unsafe condition in the fuse box.
While driving the fault indicator light came on saying that the right front headlight was out. After parking for a period of time and restarting the car, the mmi was indicating numerous faults with about half of the lighting on the right side of the vehicle. I took the vehicle to a vw dealer that did a diagnostic test and the result was that a fuse had melted into the fuse block and that was causing the light outages. The entire fuse block needed to be replaced and the total repair with labor was just over $600. 00. I called vw north America on 12-6-2013 and they say there is no recall for that issue on my VIN and that of course if there is one in the future that I could possibly be reimbursed at that time for some or all of my expenses.
