Engine abruptly stalled entering large multi-lane intersection, as engine repair light came on. Suddenly inoperative power train on the vehicle without any prior warning. Tdi diesel powered vehicle. Towed to dealership and diagnosed with hpfp (fuel pump) & fuel system failure.

While the car is in the "drive" position I can turn off the car and take the key out of the ignition. This allows the car to roll freely if on any sort of a slope.

2009 VW tdi Jetta. Engine runs rough, sutters at certain points and lacks power. Will sometimes stall in traffic. Have documented with dealers. VW America refuses to answer. VW has software fix, but will not apply it to vehicle. Do people have to be killed before these people pay attention.

During the cold winter months in nh. My 2009 VW Jetta sportwagen tdi has exhibited a engine stumble problem when it is started. The car will start but run rough and abruptly stall. It takes on average of 5 starts before the engine will stay running in a smooth manner. Most of the events have been after driving more than 30 miles and parking it overnight in a non-heated garage at 44F. One occurrence was in my work parking lot after sitting 8hrs in 30F weather. This problem has occurred a total of 10 times. The problem occurs about once a week. Most recently it started and didn't run rough until I had pulled out on to the road. The engine started to run rough and I had to pull off to the side. The car had to be shutoff and restarted before it ran smooth. The outside temperature was 10F. The car has been to VW service twice. The car doesn't trigger a code for VW to diagnose, but the problem is very real. VW doesn't know what is wrong and no repairs have been made. The car could leave my family stranded in cold conditions or possibly hit while the car is on the side of the road.

2009 VW Jetta tdi (turbo-diesel) equipped with dsg (direct shift gearbox) transmission. Vehicle prematurely downshifts from 2nd into 1st gear at slow speeds. When driving in 'tiptronic' (manual) shift mode at slow speed conditions, such as right turns, parking lots/garages, yield conditions, etc., the vehicle will downshift unexpectedly from 2nd gear into 1st after reacceleration has already begun, resulting in the engine's rpms to "skyrocket". if this occurs within a turn in traffic, the vehicle's acceleration is stalled due to the lower gear. Panicking, one shifts the vehicle into 2nd at the high rpms and the transmission jolts under the power and causes the vehicle to surge forward rapidly under power. This has contributed to near rear-end crash situations for both drivers following at the downshift/stall condition as well as vehicles in front at the upshift/acceleration condition. In parking lots while moderately traveling in 2nd gear looking for a parking stall, without warning, again the vehicle will sometimes downshift into first causing this braking "bucking' effect and the engine rpms skyrocket until one either lifts off the accelerator or shifts back into 2nd. This condition has been intermittent for over a year now an overall makes it very difficult and unnerving to drive in stop and go traffic, parking lots, areas with speed bumps, garages, or any other slow speed environments where one would prefer to operate the vehicle in 'manual' shift mode as provided by the dsg's design. It seems apparent to me that the software and/or sensor components related to the shifting characteristics of the dsg while in these modes, should not allow the vehicle to downshift into the 1st gear unless the vehicle comes to a stop, or at least at an almost non-detectable speed, thereby allowing the driver to reaccelerate in 2nd which, in combination with the high-torque nature of the diesel engine is more than sufficient for these scenarios.

Dsg transmission at slow speeds will suddenly downshift into 1st causing abrupt engine breaking in traffic without warning (<25mph). Trying to accelerating from the slow speed or stop will causing a 1-2 second delay/jerk in traffic (narrowly avoiding being rear-ended in stop-go-traffic).

While driving my 2009 VW Jetta sportwagen tdi with dsg transmission 65 mph on freeway, car had approximately 1175 miles on it, sudden loss of power, felt like the car was in neutral though was still in drive. The gear indicator lights flashed and no acceleration response when accelerator depressed. Gear re-engaged approximately 5 seconds later and was able to regain speed with no incident. Took into VW dealer, they were unable to reproduce, but called VW tech and were told to replace the input temperature sensor on the transmission. Sensor was replaced and I got the vehicle back 5 days later. Appears to be running fine, no repeat of "false neutral" in this case, there was no accident or injury, but sudden loss of power on the interstate in traffic could very easily lead to accidents and serious injury or death.

Dsg transmission mechatronic unit failure (integrated cpu unit) resulting in severe to erratic behavior of the car. Cars would suddenly stall... buck or lunge forward or backward depending on the shift mode. Many people are complaining on the vwvortex website about this most recent and severe transmission malfunction. VW is taking up to several months to repair cars. It appears to be VW-Audi cars '08 through present that are severely affected.
