Engine failure at 170,000 due to timing chain tensioner failure. Engine died at 170,000 miles due to the failure of a part that has failed. If we had known that this is a issue we would have replaced the inexpensive part at the timing belt replacement interval for a nominal amount. Engine failure while vehicle was in motion on a city street. Now we have a car worth nothing.
Son was driving down highway and front end of vehicle started to shake then stalled and would not start. Towed to independent mechanic. Replaced hpfp ($1500). Now told the timing chain jumped and has to be replaced with timing sprocket, timing tensioner, and intake came shaft. Not sure if there is damage on engine bottom as well. The cost is over $2000. Vw does nothing but does acknowledge faulty parts. My sn could have been killed on the highway. This car has 78,000 miles. It should not stall at 65 mph.
