Filed Mar 1, 2025 · Engine, Transmission · PA

Was just driving down the highway at normal speed and my car lost all power, every like came up on the dash and disabled my power steering causing me to almost crash. Took it to the shop mechanic tells me the turbos failed due to oil screen and it will cost me $8,000 Not sure why they failed I have amazing service records on my car. This needs to be a recall.

I noticed my car wouldn’t engage in reverse when shifted so I took it in for a transmission flush and it was performed and 2 days later I got a light on dash saying transmission overheating . And the car completely lost power while on freeway and went from 60 to 20 miles per hour and will not shift past first gear . So I took it back in to dealer paid diagnostic fee and then was told my transmission was bad and had to be replaced and was quoted a price of 15683$

Turbocharged failed while driving in afternoon traffic, leaving car stranded at heavy traffic stoplight until tow could be arranged. Failure occurred while idling at the stop light. Failed turbochargers are available for inspection. Failure was initially diagnosed / confirmed by dealership (Audi Chantilly) but due to extreme cost of repair quoted by dealer, car was transported to an independent garage for the repair. Failed turbocharger was inspected at dealership using micro-camera for diagnosis of the problem. There were no warnings, check engine lights, strange noises, loss of power, etc..; failure was total and instantaneous. Additional information: This is a totally stock vehicle, no modifications or tuning performed. It has never been raced or abused. The 'launch mode' built into the car's design (for fast acceleration from stop) has never been used on this vehicle. Put simply, this vehicle was 'babied'. For the initial life of the car, all maintenance was performed at dealership (Audi Chantilly) under service contact. Upon expiration of service contract (~65K miles) all service was performed by owner. Knowing of the turbocharger oil feed defect present in this model Audi's design, owner increased oil change service frequency to (unsuccessfully) try preventing turbocharger failure. All owner supplied oil change materials (oil and filters) were consistent with Audi factory requirements.

Repaired at my (significant) expense. Vehicle is completely stock. No engine modifications. 93 octane gas. All maintenance as per manual.

The turbos on the car both broke at the intermediate shaft before 75,000 miles. The car was cruising on the freeway, and the moment I slowed down to take the exit, the car lost power and shut down. I had to make an emergency stop on the side of the exit with little to no room to pull over.

I was driving at approx 65mph on the highway when all of a sudden I lost significant engine power in my vehicle. I tried to accelerate and could not so I pulled over and the car immediately stalled and I had to have it towed to the repair shop. The issue is a result of the turbos in my vehicle are damaged. Mechanic said there is a known issue related to a screen that filters the oil that can get clogged overtime and cause oil starvation to the turbos increasing heat and ultimately causing failure. Audi has released a tsb for this fault with updated parts however these issues continue to plague vehicles like mine that have otherwise been taken care of. The repair costs for this could be upwards of $9k all because of a design flaw. Not to mention this could be dangerous if loss of power occurs on the highway which could cause an accident.

Engine experience a sudden loss of power while driving on the highway at highway speeds. This was very scary as I was with my family. I pulled over and engine completely cutoff and failed to turn over. Had to get car towed over 50miles to the audi dealer where they diagnosed the problem as blown turbos caused by a clogged oil screen which is buried deep in the engine not easily accessible and found out audi has revised this part a few times car only had 42675k miles and was maintained through there maintenance program.
