Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Jetta 4-cyl Diesel

  • 66,655 miles


When starting to move the car such as at a stop sign or at an intersection, when putting the accelerator pedal down to start the vehicle moving, the whole car almost stalls as engine power disappears for a terrifying few seconds. This is very dangerous because you pull out into traffic and expect the car will move forward and not stall. I went onto a VW forum and learned that this is a common problem for VW.

Vehicle will not start on first 4-6 attempts after a cold snap and subsequent warm weather. Issue points to water building up in intercooler hoses. VW has tsb posted but may not fully resolve issue. 21 11 01 / 2025464 dated May 24, 2011, titled "frozen charge air cooler " engine will not start". it calls for installing a 1K0-198-803-B cold weather intercooler kit. A lot of internet discussion on this:"T=266863. Date of no start: 25 Dec 2011 (wonderful christmas gift!) location: Central New York (utica area) mileage: ~42000 significant weather before no start: Some very light snow... low of 19F, high of 39F... see took to dealer: Not that day... had a state inspection in charlotte, nc scheduled for later that week at VW of South charlotte: They found zero issues when I mentioned the problem (no codes, etc.) and didn't charge me anything for "checking it out". comments: This was the first no-start since buying the Jetta in 12/2008. Car did have weird "phantom fuel loss" issue since initial in-service date... after 6 visits to 2 different dealers complaining of issue it was finally addressed in an ECU update in late winter/early spring of 2011. Date of no start: 5 Jan 2012 location: Philadelphia, pa mileage: 44250 significant weather before no start: Cold snap the night before (mid teens F) then mean of mid 30's this day... happened in morning of 5th when it was still cold from night before. See: took to dealer: Not that day, but the day after. No faults found after a $50 diagnostics check since "car was not in warranty". dealer (fred beans VW of devon, pa) wants to have it overnight after a similar cold snap.. will provide loaner.

The contact owns a 2009 Volkswagen Jetta. The contact stated that the clutch connector was fractured. The vehicle was taken to a dealer and they advised him that he needed to replace the clutch plunger. The vehicle was repaired. The failure recurred approximately one and a half years later. The contact stated that the plunger was dangling from the vehicle. The vehicle was taken back to the dealer but they offered no assistance. The failure mileage was approximately 45,000.

During the snow storm the clutch and the four wheel drive did not engage. I was driving slowly along with the traffic and the as the car started to ascend an incline in the road, it started to skid; and when I engaged the brakes, attempted to change gears, the clutch would not engage. When the car came to a stop, there was a odor of burning rubber. I contacted VW America about the failure, they covered the cost of the part and not the service as a customer appreciation good will gesture.

My 2009 Jetta tdi engine started running rough when I pushed the clutch in while turning into a parking lot 3 weeks ago. I coasted to a parking spot and turned off the ignition. I started the car back up immediately to see if it was going to be ok and it sounded good so I shut it off. When I returned about 45 minutes later, the car started but sounded like it was running on only one or two cylinders and then died. I called a tow truck and it would not start at all when he arrived. The dealer asked if I had ever run gasoline through it. I said 'no, why would I do that"' he said that the entire fuel system needed to be replaced and that VW would pay for this 'one time' even though the warranty has run out. Well, if they are at fault this time, they will be at fault the next time too. My concern is the next time. I drive on a 70 mph interstate 90 miles round trip to work 5 days a week. What are the chances that I will be lucky enough that it did not happen in traffic at that speed the first time and just where will I be when it happens again? if they are replacing this shredded high pressure fuel pump with the same model made of the same materials, it will happen again. Is there ethanol being put into diesel in this country? what about the additives to diesel that are necessary for lubricity that are put in by the different companies? is one or more types of these the culprit" this problem is all over the internet and I hope that VW can come up with a permanent solution before someone is seriously injured - if it hasn't happened already. Meanwhile - still waiting for my car to be returned to me.

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.
