DSG transmission will abruptly shift down to first gear and would not respond in any other gear. The shift indicator in the dashboard will light up and blink and the check engine light will come on. There are no warnings before this happens and it will happen at random times. It has happen in separate occasions while traveling at different speeds. When this happens while traveling it creates a dramatic reduction on vehicle speed almost causing the vehicle traveling behind me to rear end me. Once stopped the car will only engage when put on D and will stay at a low gear causing the RPMs to red line even at low speeds making it unsafe to drive due to only being able to reach 5 to 10 MPH. A scan was performed and codes P1814 Press. Ctrl. Valve 1 Open circuit/short implausible signal, and, P1835 Press. Ctrl. Valve 5 Short circuit to B+. This fault is random and there is no warning or indication of when it may happen making the vehicle unsafe at any speed.

The wiring harness of a temperature sensor in the dsg may have connector wires that were insufficiently crimped by the connector supplier during a limited production period. With insufficiently crimped connector wires, a temperature sensor has the potential to falsely detect a high gearbox oil temperature, causing the clutch to open and can cause the driver to perceive that the transmission has shifted into neutral. If this happens, the selector lever position indicator within the instrument panel will flash. In addition, the depress brake pedal indicator light will be illuminated, alerting the driver to apply the brakes. In heavy traffic, this could lead to a crash without warning.

Purchased car in 2010 with around 10,000 miles on it. A few months after purchasing, check engine light would illuminate, vehicle would have a noticeable decrease in power and not accelerate over about 40mph. Sometimes after shutting car off and restarting problem would go away, other times it would not. Vehicle taken to Audi dealership car purchased from for repair and initially reported as sensor problem and repaired. Couple weeks after repair car would have same problem, so taken back to dealership and again repaired sensor(s). Within about the first year after purchasing, issue happened multiple (+/-5) times after dealership 'repaired' what they thought was the problem at the particular time. After about 5/6 times of this happening dealership took a more in depth attempt at figuring out what problem really was, telling me they were working directly with Audi & their mechanics to find and fix the actual defect. Car was in shop for around 3 months for this repair, which they determined was electrical and decided to rewire the entire car. In the meantime, I moved out of state to start graduate school. I finally got it back a few months later after having to pay to ship it to me and for a rental while waiting. Within a few months, car once again had same exact problem. Took to new local dealership who also diagnosed issue as sensor(s) & 'repaired' them. Continued to have same problem every few weeks, would take into dealer for repair, get it back, have problem, take to dealership, etc. Dealership would not address car overall being defective, they'd avoid contact, not return calls, hangup etc. Car eventually traded in for new make when warranty expired.

Driving 30 minutes into the highway, the vehicle decided to shift into neutral while the vehicle was in "D" drive and in motion. The "prnds" started flashing on my dash, while not letting me accelerate going 65mph. I had to quickly slowdown, and pull over to the emergency lane. The vehicle seems to have gone into "limp mode". after turning off the vehicle and turning it back on, it drove just fine. This happened once more 2 days ago. Seems like it could be the transmission control unit, however dealer cant determine the fault without a code. Scared to drive the vehicle now.

When in low gears, every action (deceleration and acceleration) are extremely "jerky". when coming to a stop audible "clunk"S can be heard from the engine area, and when attempting to fully stop the car jerks forward into first gear. The reverse and drive gears on the automatic transmission sometimes partially engage, or do not fully engage at all. On hills, the transmission has these issues as well.

Transmission problem. Mechatronic controller has gone bad. Intermittent problem. Dsg will not engage to go into reverse. Transmission acts as if it is in neutral. When placed in park, if auto is on an incline of any sort, the vehicle will and has rolled forward approximately 10 inches. The concern is that if the car will not go into reverse on command, the occupants may not be able to get out of the way an oncoming mass.

The contact owns a 2009 Audi A3. The contact stated that the rear differential failed while traveling 60 mph. The failure felt as if the brakes had engaged independently. The vehicle was still able to be driven, but the vehicle ran would drive roughly. The vehicle was taken to the dealer where it was determined that the rear differential needed to be replaced. The failure and the current mileage was 75,000.
