Defective fuse link in wiring harness melted together rather than separating causing very high voltage damaging the cpu and ignition coils causing piston misfiring and possibility of engine fire. I have retained the defective part. Mechanic reports both fuse links connecting to two coils are melted and 30,000 volt power bridged these links to damage the other electrical components. Repair was over $2700. Fire was avoided by taking vehicle out of service but severely melted links and high voltage feeding back into electrical system caused very high potential of electrical fire in vicinity of fuel sources. Vw notice to mechanics about problem has been issued but no recall.

The car had an extreme misfire at idle and very rough running. I took the car for an inspection at the vw dealership. They told me the problem was that the chain had stretch because they were unable get an stable timing. After dissembling the opening up the house covering the timing chain they informed me that the cam screen had come loose and liking caused the chain to stretch. Vw told me it would be wise to have the cam replaced in case the screen caused any damage it to it as well. After the repair was completed I asked them directly if the tensioner had failed and they then admitted that the engine failure was the result of bad tensioner not a stretched chain. The vw manager told me he was aware of the tbs on the tensioner failures. The manager choose to make up an unbelievable story to cover the true problem. The chain was not stretched and there was no damage to the cam shaft. I directly complain to vw and they told me in a letter the "tsbs don't indicate trends among our vehicles, as they are issued to out dealerships for instructional purposes only." this is a carefully constructed statement to obfuscate the truth. Initial failure occurred on the highway at 65 MPH. The mileage was 77300. The failure on this engine appears to have spared damage to the valve but a more serious failure could have shut down the car in the middle of a 4 lane highway.

I was turning left off of a hwy. I attempting to accelerate to 40 miles and the car hesitated like it was switching gears, decreased in speed and started shaking. I pulled over, checked the gas cap, - it was closed. Turn car off for a few minutes, restarted, car still shaking. I drove the car to safe place off the road. The car would not accelerate past 20 miles hours. I put the hazard lights on, but they kept going off. Then I called the tow truck. The car had received scheduled maintenance including spark plug changes two days ago, but then this happened. Volkswagon dealer service folks said the problem was the ignition coil misfired. Originally charged 300 to have it fix, then discounted and paid 200. I see there are numerous recent complaints about the ignition coils in the years around my model year, and volkswagon recalled the ignition coil a few years ago for older models. I think they need to extend the recall to cover the 2011 year. This is a safety hazard. I reported it to volkswagon. The car behind me almost hit me in the back. A block further I would have been on a highway driving 70 miles per hour. I love my volkswagon, but this was a dangerous situation.
