Timing Tensioner problems of the 2010 Audi A4

I was driving to work and as I slow down to park I heard and felt a pop in the engine. Luckily I was able to use the momentum of the car to park. The engine would not turn back on. After work I went back and the car would not turn on. The engine would just clank really loud. I had it towed home and the next day I called the mechanic. I then towed the car about a week later to the mechanic for him to check it out. After a few days he said that the engine chain tensioners broke and caused catastrophic damage to the engine. The repairs would cost $4800 and or we can put a new engine for $6300.

Fully stock engine and drive train car experienced a timing chain tensioner failure. Being an interference engine, this cause catastrophic damage and the car requires a new engine. I was fortunate this happened while stationary at a gas station. I had driven about 100 miles and stopped for gas. Attempting to start the car yielded cranking but no turning over. The car was towed to a mechanic who confirmed the failure via engine compression. The failure could have happened while on my highway drive at highway speeds putting myself and the drivers around me in danger. This is a known issue and a class action settlement is taking place. The manufacturer should be forced to recall all affected vehicles for tensioner replacement.

Timing chain tensioner failed causing catastrophic engine failure and stall on city road intersection full of traffic.

Timing chain tensioner failure. Causing significant engine damage.

Timing chain tensioner failure. The failure caused the timing chain to jump, throwing the pistons out of sync, causing damage to the valves. This occurred when first starting the vehicle.

Catastrophic engine damage caused by failure of timing chain tensioner. No early warning as vehicle was serviced the day before by Audi dealership and oil capacity and pressure were within manufacturer's tolerance. Vehicle was in motion at slow speed when check engine light came on.

Engine misfire likely due to timing chain jump. Extensive repair to engine including intake valves, timing chain, tensioner, and several related parts. At the time of the malfunction, the vehicle was being driven in albany, NY, during heavy traffic. The malfunction could have resulted in personal injury to occupants in this vehicle as well as to other vehicles. Cost of the repair was $3,194. 46, and resulted in loss of the vehicle for 9 days.

I was lucky that my car did not fail while driving down the highway like other owners with this problem have. The timing tensioner and chain failed, causing a costly repair. I understand that there are three class-action suits against Audi-vw regarding this problem, yet no recall. Why? I want Audi to pay for this costly repair and have a recall. I can send photos if necessary.

The timing chain tensioner broke causing the engine to completely stop which made the car unable to move or respond in any way. At the time the vehicle was stationary but completely disabled.
