Upon reaching approximately 75,000 miles, I began noticing a louder than normal noise when starting the engine. The noise continued, and around 80,000 miles, I began receiving a check engine light for cam position limit. I did a lot of research and diagnostics to find that the timing chain had stretched, causing the noise and check engine lights. I had the faulty timing chain replaced, luckily before any severe damage had occurred. The timing chain should not need replaced that early in the life of the vehicle, but this problem has plagued the vw/audi 2.0 engine, even after the timing chain tensioner update. This could have been catastrophic. Many owners have not been so lucky and have required engine replacement due to valve damage from timing chain stretch at even lower mileage.

41 days after purchasing well cared for, used q5, began experiencing rough ride over highway stretch, with intermittent epc light and constant check engine light. Engine also revved at stand still and vibrated. Unknowing of current class action lawsuit involving the timing chain, took the vehicle to a local mechanic. Mechanic indicated the timing chain had been stretched beyond safe use and the timing chain and tension adjuster needed to be replaced ($2600). Following those repairs, I was informed that due to the damaged timing chain, the cam shaft was also not functioning correctly which required replacement as well as the camshaft positioning sensor. (new cost - $4900) following those repairs, the issue still remains. Mechanic believes the issue is now oil pressure leaving the cam shaft due to a likely issue with the non-return valve leaving the camshaft bridge. This pressure prevents proper function of the variable valve timing, causing a vibration and rough ride. Mechanic offered to replace non-return valve (additional $3000) but can't be confident that it will alleviate the problem. Additional option was to replace engine beginning at $7000.00. Working with audi service to schedule time to address previous recall issue (coolant pump) when they will take a look at the engine issue and explain options. Class action lawsuit opt-ins were due by 10/13/18, 11 days after I purchased the vehicle, 30 days before I began having issues.

While driving 70 MPH on interstate 68 the engine light went on followed by the epc light. The car lost some power and the car began to sputter. By reducing the car speed to 40 MPH I was able to exit the highway and pull into a car repair facility in hagerstown, md. I has the car towed back to the audi dealer in tysons corner, va. It was determined that one of the four fuel injectors had failed which caused it to remain in the open position. The fuel injector was replaced. The service facility could not explain what might have caused the fuel injector to fail. They did test the other three fuel injectors and indicated they were fine. My car has approximately 57,000 miles on it and I am interested in learning whether you are aware of other fuel injector failures in this or other audi vehicles.

Unexpected braking. I at once pulled off the road into a driveway and attempted to place the vehicle in park but was unable to shift out of drive. I eventually was able to stop the engine with the shifter still in drive. I contacted the dealership and roadside assistance. The vehicle was towed to the dealership. After 3 days at the dealership, I was told that diagnostic tests did not reveal any problem and that the dealership was unable to recreate the problem. The vehicle has been returned to me and I am awaiting further communication from audi and/or recurrence of the problem. This has been the second problem I have had with this vehicle. The first problem occurred on the way home after purchase.. While driving, the check engine warning light came on. I contacted the dealership and was asked to return the vehicle to the dealership. After undergoing diagnostic testing, it was determined that the air intake manifold needed to be replaced.
