Timing Tensioner problems of the 2010 Volkswagen Tiguan

Timing chain tensioner failure, causing catastrophic engine failure at 77,000 miles. A newer model of timing belt tensioner has been used since December 2011. Est. $5000 repair bill.

On December 7 2017 the engine started miss-firing, on next restart the engine destroyed itself, caused by 'jumped timing' do too a defective chain tensioner.

Another example of the well known, well documented, and prone to failure timing chain tensioner.

Timing belt tensioner failure without notice happened while driving from parking lot chain skipped because of chain tensioner failed causing chain to skip a tooth making the timing issues. Towed to mechanic.

From mechanic at vw roseville. Chain tensioner failed causing slack in timing chains, which caused chains to jump time and caused upper cylinder head damage. Car has 87,702 miles.

Car had 90,000 miles and started having ticking engine noises. Vw dealership service technicians diagnosed the issue as a turbo waste gate noise ("nothing to worry about at this time"). Two days later the engine starts to act like it's misfiring almost bucking then within minutes the engine goes(won't start, trying to start engine just 'spins'). Towed back to service. Internal inspection from their technicians confirmed bent parts, etc - $8,000 to replace engine. My research indicates the problem was with the 2. 0t tsi timing chain tensioner failure as listed in NHTSA service bulletin #tb-15-12-01 NHTSA item number 10045560. Certainly the results indicate that was the actual problem. According to the TSB it seems like this is a known issue across many vw models/years. Why owners are not notified of this potential issue and given a chance to take action to fix it before something catastrophic happens is disheartening.

The timing chain skipped or broke which caused a failure. It could not be determined if the timing chain was the first to fail or if something else (tensioner failure) caused the timing chain to break as a result. This resulted in the vehicle being towed to the dealer since it was not safe to drive. I was lucky this occurred when the vehicle was idling in a turn lane. While idling, the vehicle started shaking rather violently fore/aft. I immediately pulled of the road and turned off the vehicle.

Our Tiguan started shaking and making a horrible noise when our 20 year old daughter attempted to start driving. She noticed the check engine light on and the car suddenly stopped in the middle of a city road- presenting a danger to her as she could not move the car and was not in a safe neighborhood. She had to wait for a tow truck. At the repair shop, it was determined that the timing chain and tensioner were bad so they were replaced. After this repair the car still would not run so it was towed to a Volkswagen dealership. They tore down the engine and determined that it needed to be replaced. The cost at the first repair shop was nearly $1600 and the cost to replace the engine is nearly $9000.

One night I parked my Tiguan everything was ok, in the middle of the night my wife was getting ready to go to work couldn't get the car started. Next morning I rented an obd2 scaner and read the codes. Had the car towed to the dealer ship. Next day they called me and told be because of the timing chain tensioner failing my motor basically grenaded and they needed $7216 to repair. The car had 62k miles and it was 6 months passed warranty. I contacted customer care and they only agreed to cover 50% which leaves me with 3k bill that I couldn't have avoided. I never knew the Tiguan had a 10k mile oil change service so I always changed at 3k. How could have I avoided this failure.

The contact owns a 2010 volkswagon Tiguan. While driving at various speeds, the vehicle became unresponsive and the engine would not operate as normal. The check engine light illuminated. The vehicle was towed to the dealer where it was diagnosed that the timing chain tensioner belt failed and the engine would need to be replaced. The vehicle was not repaired. The manufacturer was notified. The VIN was not available. The failure mileage was 83,000.

While driving 25-30 mph on a city street, vehicle stopped accelerating (much like running out of gas. . . ) dealer states timing chain tensioner failed destroying engine-I understand vw has a TSB out on this for years and though I serviced my vehicle at dealer, never knew of this potential problem.

Driving on freeway at 70 mph and experienced failure of timing chain tensioner. Cam skipped chain and caused pistons to impact valves. Total and complete engine failure that was sudden and unexpected at highway speed. My research finds that vw is aware of this problem but will not issue a recall.
