The wiring inside the headlight assembly has insulation that degrades with the head generated by the low beam/daylight running lights. It becomes brittle and falls off creating bear wire shorting hazard. The light assemblies are such that the wiring cannot be accessed to replace with high temp insulation. Vw only replaces w/ the same entire assembly which does not correct the hazard & costs $800 to replace both assemblies. I caught the defect when replacing a light bulb. This affects more than the Tiguan model.

The epc light came on many times between 2011 and 2014 and the electronic throttle kicked out of cruise control. Miller vw checked the car July 2011, did not have a solution and cleared the codes. I asked our local mechanic about it in July 2013 who identified that there was a TSB for the throttle body wiring harness. We continued to observe the intermittent epc fault response but experienced no problems. The first major incident occurred 28 June 2014 entering I-89 north when entering traffic the epc and engine fault lights came on and the engine lost all power jusy as we entered the travel lane. The car went into limp mode and would go no faster than 35 mph I switched off the engine while traveling which reset the throttle fault allowing us to continue traveling. This is a short ramp and there is no shoulder at the end of the ramp. I made an appointment for the car at walker vw to repair the car on 2 July. The service department was unable to make the repairs that day as they did not have all of the required parts on hand. On 22 July my wife was preparing to enter I-91 from route 5 south via a left turn on ramp when the epc and engine fault lights came on and the engine went into limp mode just as she was preparing to turn into the on ramp. A tractor trailer was rapidly overtaking her in that lane in a driving rain and the car would not exceed 20 mph. She turned on the flashers and the overtaking trucker veered into the right lane avoiding collision. I then made an appointment with our local car repair shop and trusted mechanic at kingdom imports. They ordered the parts and installed the replacement wiring iaw the TSB on 29 July 2014. Even after ordering two complete sets of parts vw did not include the shrink tape required to stabilize the wiring. Vw has chosen the worst solution and should issue a recall and install a purpose built wiring harness.

2009 vw Tiguan. The wiring to both high and low beam lights is faulty. The insulation around the copper wiring to all lights has cracked off exposing the copper wiring. As a result the lights frequently do not work properly leaving me with a headlight that does not function. This is extremely dangerous when driving at night. The local vw dealerships fail to acknowledge the problem. Which leads one to think that vw american fails to address the problem. This is not an isolated problem but widespread. Replacing the bulb is only a temporary fix. The problems persists because of the faulty, cracking wire insulation. Vw will charge $800. To replace both light systems. Their reason for the high cost is the labor involved. They say the front bumper has to be taken off to complete the headlight lamp replacement. This is a factory defect that vw needs to address. Wire insulation is not suppose to crack making the light inoperable. Yet the dealership explanation says it's "due to wear". Well, why aren't any of the other wiring systems under the hood cracking? because they are not suppose to. That's why. This is extremely frustrating to know that I have to pay an exorbitant amount of money to replace the headlight systems. Someone please initiate some action.

While operating the 2011 Volkswagen Tiguan, on the highway at speeds of approximately 65mph, experienced an electrical failure that caused a headlight / driving light / turn signal / brake light / marker light and plate light failure. The failure became intermittent until taken to the dealership for service. Dealer stated "looked up wiring diagram and traced to a fuse in engine fuse block. / fuse not blown, but has corrosion. Removed fuse and found fuse block melting. Needs fuse and block. Replaced both and lighting ok now.

2010 vw Tiguan, with repeated engine failures associated with power steering module, boost selenoid / engine coils, wiring harness, fuse re-call, loss of power / thrust / electrical panel instability, beginning in July 2013 upon the limited wolfsburg platform. Service was provided by a vw dealership, 16 days prior to the August 2013 accident. The car was not returned to me until October 1, 2013. (almost 8 weeks) a rental car was applied, but there was significant out of pocket expense for taxes / fee's for a 2 month rental. The vw upon return oct 1, 2013 then broke down again on oct 9th, for electrical failure again. The car was towed back to vw dealership for repair. I was given a complimentary loaner car. The vw was then returned and then ran without significant incident until March 16th, of which the engine failed for engine coils, and was towed back to the vw dealership for service, the car then experienced another electrical mechanical failure on 3/25, resulting in a 2nd front end collision. I received a not at fault decision on the first accident, per the commonwealth of MA.
