Audi Q7 won't shift problems

Filed Sep 28, 2026 · Electrical, Engine · NY

While driving, the vehicle displayed an error message (occurring when going downhill), limited engine RPM to 1200, and illuminated a warning instructing the driver not to exceed 1200 RPM — a limp-mode condition that severely limited acceleration and the ability to maintain speed in traffic. On other occasions the vehicle entered limp mode and shut down while driving. The selling dealer, Audi Mohegan Lake (Mohegan Lake, NY), checked all systems, stored fault code P060C00, and stated a software update was needed, referencing TSB-2067767 — but advised the fix was not available. Audi was unable to diagnose or repair the defect. A buyback request was filed in April 2023 (Audi case AU-2023-0468) but never resolved; with no repair available, the vehicle was traded in November 2023.

I was traveling at highway speeds in active, high-velocity traffic when my vehicle suffered a sudden, catastrophic mechanical failure that nearly resulted in a severe multi-car accident. Without any warning, the vehicle completely lost its ability to accelerate, flatly refusing to pick up speed or maintain momentum despite pressing the gas pedal. ​This unexpected, immediate drop in propulsion marooned me in high-speed lanes, leaving the vehicle dangerously vulnerable as oncoming traffic rapidly closed the distance behind me. Drivers behind me were forced to aggressively swerve and brake to avoid a high-speed rear-end collision. Moments after this life-threatening loss of power occurred, the Check Engine Light illuminated on the dashboard. ​Subsequent technical inspection revealed a severe engineering defect: the internal seals of the factory coolant control components failed, forcing pressurized engine coolant backward into the engine’s primary vacuum system. This pressurized fluid completely contaminated the vacuum lines, the vacuum reservoir tank, and the electronic solenoids—including the N75 boost control solenoid. By filling the vacuum infrastructure with liquid coolant, the engine was instantly starved of its ability to regulate turbocharger boost, triggering a critical "limp mode" and a P0299 underboost fault. ​The catastrophic failure of an internal cooling seal directly compromising an active drivability safety system represents an unreasonable and severe defect. It transforms a routine drive into an immediate, uncontrollable highway hazard. I am filing this report because this known coolant migration pattern presents a clear, present, and life-threatening danger to owners operating this engine platform.

Lights on dash were flashing in cluster which made it look like it was low tire pressure. I had a portable air pump which showed tires were fine. The vehicle went into some kind of limp mode which prevented the vehicle from driving the speed limit. It was taken to Auto service center. The diagnosis was Engine failure due to a burnt valve. It's been confirmed through the dealership, mechanics and consumers that is a common problem with this particular make and model vehicle. This engine failure left me on the side of the road and not feeling safe at all while being approximately 3 hours from my home. As an Audi owner I'm was so disappointed to be told that I needed a new motor even though it still runs in limp mode. This vehicle has less than 150k miles. It was the best European vehicle I ever owned until it wasn't. Bad call and poor quality control Audi!

When driving into a dimly lit area the car rings and displays the message front left side marker defective. The warning stays on for some time and then goes away before returning again. This continued for a few weeks. The car then experienced a full electrical system malfunction, doors unlocking and locking randomly while driving before dinging repeatedly with multiple warnings displayed in the dash and then stalled in the middle of the road. The vehicle would not shift into park. Multiple warnings continued to ding and flash in the dash. After being turned off for 20 minutes the car was able to be started shifted into Drive and driven with no warnings displayed. The car was taken to the dealership for diagnostics which were performed, but with no electrical system malfunction displayed. The left side marker warning was still on, but the dealer said there was no fix for this. The following month the car was taken for 60,000 mile service. At this time the dealer advised the fix for left side market was replacing the entire headlamp fixture. The service was declined. When the vehicle left the dealer the cruise control was on and would not turn off. After turning off the car and turning it back on the cruise control was off.

My car had gas in the vehicle and as I was stopped to take a turn the car shut down on me and would not go into drive. I had the car towed to the dealership and was told that the car had no gas in the vehicle, but the fuel gauge was reporting that I did have gas in the tank.

When I was driving and trying to make a right turn to merge into the traffic, the transmission suddenly stalled and stuck in neutral, put my car in the right lane with large traffic on the lane and forced other cars to make sudden stop. After restarting the engine multiple times, it was suspected that somehow the transmission is always in neutral while the onboard system showing it is in driving mode. I had to get out of the car to push it to a safe side road. This is all sudden while car engine is running. Initially the onboard dashboard shows Transmission Malfunction, but after restarting even that error message disappeared, while the transmission is still not engaging.

I have a 2009 audi q7 diesel bought from dealership march 2019 after it had been sold to the public once audi did emissions recalls , after I bought this vehicle had issues with it 10 days after I bought it I took it back dealership wants to have nothing to do with helping me even though it still has an extended warranty for 4 years more from the manufacturer, I have a flashing glowplug and limp mode vehicle that when driving it and glow plug goes on while I am on the road vehicle slows down from going 65mph to approximately under 15mph in just seconds engine loses power and its a safety hazard while on the freeway . Audi dealer claims I have fuel contamination but when asked to prove to me this through fuel being sent to the lab they have no such lab results . They just claim I had this in order not to honor my warranty which is very fishy since I bought vehicle once they sold it out to the public after recall had been supposively fixed for emissions. I had fuel pumps replaced fuel pressure regulators and injectors as well all paid out of pocket vehicle still states code poo88 and code p0087 changed fuel filter also and now catalyc converter code is on also I feel they need to honor my warranty since fuel was never tested through a lab and its just by word of mouth that they claim I had contamination . Vehicle still being worked on but all costs out are out of my pocket eventhough my warranty booklet from the manufacturer states I should be covered for fuel rails, pumps, catalyc converte etc..

5 times in the last 6 months the "glow plug" indicator light has come on and the vehicle experienced a loss of power. Twice the car completely broke down, twice audi could not replicate the error code, the last time this happened I had just picked up the car from audi after it was repaired. The glow plug light came on and it went into "limp mode" where I experienced a loss of power as I was getting on the freeway, almost got hit as I couldn't accelerate past 35 MPH.
