My wife's 2010 jetta 2.0t tsi experienced an engine stall and complete loss of power while driving at approximately 40 MPH on a straight section of city street. This was a routine trip under clear weather conditions. With no traffic behind her, she safely coasted to the side of the road. After waiting 5-10 minutes she was able to restart the engine and, with no check engine lights appearing, drive approximately four miles home. The following morning, upon starting the engine, multiple cylinder misfires began occurring and the engine was immediately shutoff and the car was towed to the dealership for diagnosis. The dealership discovered that the stall was due to the timing chain tensioner failing, which allowed the timing chain to skip six teeth on the camshaft and the valves to contact the pistons resulting in the engine self-destructing. They recommended a nearly complete engine replacement at a cost of over $8,000. The car was purchased brand new in 2009 and has been maintained impeccably as specified by vw. Speaking with the dealership engine technician, we learned that the timing chain tensioner is a known defective part by vw and that in 2011-2012, was revised several times in an attempt to mitigate the failures. A technical service bulletin was issued by vw to dealerships and service departments explaining the issue but no notices or recalls were sent to customers informing them of this potentially deadly component failure. I have read, but not independently verified, that vw has issued a recall for this specific component in europe. Since the beginning of 2016, and owing to the significant safety hazard, as many as three class-action lawsuits have been filed against volkswagen for this specific component failure. We are thankful no one was seriously injured or killed when the car stalled during operation, but now we are facing over $8,000 in repairs.

P2015 - intake manifold position fault. Intake manifold valve malfunctions and sticks causing a severely rough idle and engine stall. The car was attempted to be started after sitting overnight in a garage. The car successfully turned over, but was in a very rough idle for a few seconds before stalling. Car could not be run continuously at all at this point. This problem began to occur around 80,000 miles, with no initial performance impact, but the part ultimately had to be replaced at 88,000 miles when the incident described above occurred.

This vehicle has been an electrical night mare. Started off around september of last year with an intermittent misfire. Dealer replaced intake assembly. A month later random cylinder misfires. It comes and goes with mil light coming on. Been in to dealer a couple times for this issue and they have not been able to resolve the issue. They keep wanting more money to diagnose. In january the battery kept dying. If it sat over night the battery would be dead. 1 year old battery. Had charging system checked at autozone and everything was good. This morning my wife went to drive car and the radio would not power up. So I started searching the web just like every other time we have had issues with this car. Turns out hundreds of 2010 models have had same issue and seems to lead on to more electrical issues down the road. I have had 15 year old vehicles with almost 300k miles and same factory radio in it working fine. I just traded off a 2001 explorer with 200k miles that ran better than this 5 yr old jetta. Voa gave me a claim number and want me to take it to a dealer which is ridiculous because I will be charged diagnostics and will not be covered as it is a luxury item. What about all the other electrical issues they have been unable to resolve.

Driving at about 40 MPH with about 1/4 tank of gas when car started to sputter and run rough. The glow plug indicator light began flashing and I pulled into a nearby parking lot where I shut the car off. I restarted the car and pulled out of the parking lot but car immediately began to run rough and lose power again so I pulled into a gas station lot where the car refused to restart. Called a tow truck and got car towed to autobarn in countryside (where I bought the car). Tried to restart car again at dealership and noticed the fuel gage was reading "empty", meaning fuel had leaked out since the car died. Dealer called me the next day saying my high pressure fuel pump had failed and my entire fuel system from the gas tank on up to the injectors had to be replaced. Was covered under warranty and dealer was very helpful and did the job in four days, during t-giving week, which I was very satisfied with. I always get my diesel at bp amoco's or mobiles and make sure to use heavily trafficked station to have the best chance of getting fresh fuel. I am not comfortable driving the car and have considered trading it in due to vw corporate's seeming indifference to the problem, which is well documented online and there are many many cases similar to mine. Shortly after I bought the car I noticed that all the fuel stations in my area went from 5% biodiesel to 20% biodiesel. I asked the dealer at the time about it because the owners manual states vw will not warranty the car if anything more than 5% biodiesel is used. The dealer said vw would warrant it and a written statement from vw came in the mail shortly thereafter. I can't help but wonder if the higher biodiesel percentage LED to the failure.

Owned my 2010 vw jetta sport wagon tdi 6sp man since new. It has always had an interment cough & sputter that would happen at any speed or condition, but was very infrequent an non-repeatable. Now however, starting at around 85,000 miles, the cough and stall has become more frequent, causes the glow plug indicator light to flash and the vehicle loses power (goes into limp mode?). This used to all reset when turning off the key. The last time I brought it to the dealer, parr imports in bremerton wa, at 89,802 miles it had p0322 & p0651 fault codes. They suspected an intermittent crank sensor fault and wanted me to monitor. It has progressively gotten much worse, I have now lost power in heavy traffic and stalled in the parking lot pulling onto the road and have had to switch vehicles when it would not reset leaving the house. I was compelled to buy the torque application for my android phone to view and reset fault codes. I have not reset the ecu faults at least 4 maybe 6 times and now, at around 92,000 miles, it shows 5 codes and won't reset: p0322: ignition/distributor engine speed input circuit no signal, p2127: throttle/pedal position sensor/switch e circuit low input, p0193: fuel rail pressure sensor circuit high input, p0651: unknown code - more information may be available on the web, p0300: random/multiple cylinder misfire detected. My internet research suggest the high pressure fuel pump (hpfp) may be an issue with vw blaming it on gasoline contamination, however I have records and receipts confirming I always fuel with diesel from a major distributor.

Vw jetta sportswagen tdi 2010 53,000 miles. On aug 7, 2013 at approximately 16:20, while stopped at a traffic signal, engine begins to run slightly roughly, but not sufficient to be of concern. Accelerate from traffic signal towards onramp to i195. Suddenly engine dies (before onramp). Coast car into parking lot at side of road. Total time from beginning of rough idle to engine shutdown was about 10-15 seconds. Had failure occurred on interstate i195 or i95 during rush hour, this would have been a dangerous condition -- possible stranding of car in a travel lane or dangerous crossing in front of faster moving traffic to reach shoulder. Called for tow and car towed at about 19:00 to vw dealer - west broad volkswagen in richmond va. Dealership is closed so leave car at dealer. Spouse drives from home about 100 miles to pick me up. Reach home by 23:30. On aug 8 dealer diagnoses as a failed high pressure fuel pump (tdi diesel engine) with metal particles throughout the fuel system. Vwoa tech line indicates that entire fuel system needs to be replaced. Car is out of warranty, but dealer asks vwoa to cover part or all of cost. On aug 9 vwoa approves repair and agrees to pay in full. Work completed on aug 12.

I was at a light in first gear at a complete stop. The engine was idling rough. (not the first time, but vw couldn't find anything wrong). The RPM on idling is normally 800. It was up to 1,000. It sputtered twice and hicupped from 1000 to 700 to 1000 to 700 in the period of 3 seconds. My clutch was in as was the brake and I was in first gear since I was at a light but at a standstill. The car subsequently stalled without me having moved the car. The car restarted and I still detected the rough idle.

I had come to a full stop and was idling at a red light in a busy intersection when the engine stopped suddenly. No misfiring or rough moments before stopping, just a sudden cut off. I put the engine in park and tried restarting the engine. No success. I put the engine in neutral and got a push to the side of the road. Tried starting the engine several times, in park, with no success. Vw called a tow truck. Before accepting a tow I turned the ignition fully off and tried restarting the engine. This time it started. I cancelled the tow. Car is running normally again. This sudden stopping of my engine happened one other time when the car had about 4000 miles on it. I was pulling out of a parking place and the engine shut off as I was pulling forward after just having put it in drive. I restarted the car and a few seconds later the engine started misfiring, but only for a second. Then it ran fine. No further mishaps until may 17, 2011 at 17,500 miles. I notified vw of the mishap when I took it in for it's first check-up. Vw said they didn't find anything wrong and didn't know why it happened. I currently have a call in to vw again, but have not yet heard back from them.

Multiple incidents that appear to be the same problem/defect. 1. The car sometimes will not start for several minutes, and once it does finally start, has a very rough idle and stalls. After several tries, it finally starts and runs normally. This has happened 7-8 times from july 2010 until the present. 2. Now, over the past two months, the car tries to stall out while driving also, and has resulted in my wife having to pull off the road and restart the car. This has only happened twice so far, but the starting and rough idle problem continues to occur approximately once every couple of weeks. On another note, I want to ensure that if any recalls occur as a result of everybody's complaints, that u.s. Military stationed overseas are not left out. Many of us purchase these u.s. Spec cars from local dealer agencies who (re)import the cars back to europe for this purpose. Oftentimes recalls are not enforceable overseas, however, this is a volkswagen and there are plenty of authorized vw dealers in germany, and in europe as a whole.

1) over the past three weeks, this vehicle has experienced symptoms of drawing water through the intake and cylinders on startup on 5-6 separate occasions. Symptoms include: rough idle (as though misfiring on one or more cylinders), white smoke, difficulty gaining engine RPM, and stumbling for first 30-60 seconds of operation until "cleared out". On one occasion, the starter motor would not turn over the engine due to "hydrolocking" phenomenon. When the starter was released and cranked again, the car cranked very slowly, caught, and started extremely roughly, and needed significant nursing of throttle to "clear out". I took the car to the dealer on december 8th for the above behavior. They could offer no explanation, no fault codes stored on computer. 2) on december 14th, driving home in a rain and snowstorm, my car went into electronic limp mode on the highway at 70mph. The dash flashed "service engine now", the glow plug light flashed, and power was cut. I took it to the dealer the next day - they found the intercooler and pressurized intake lines full of 1-1.5 cups of ice and water. This failure occurs often, each time the car is run for an hour at humid below freezing temperatures. When the car is shutoff and allowed to warm to above freezing, liquid water is drawing directly into the cylinders. The consequences of this can include: limp mode, rough starting, and completed engine destruction by hydrolocking and bent or broken connecting rods. I strongly suspect my engine is permanently damaged. 3) the dealer drained out the water and reassembled - said they consider the car fixed. They have not addressed the root cause of why the pools of water are present in the intake during startup after running in humid freezing conditions. The cause is icing of the intercooler during normal operation, which is a design flaw uncontrolled by the user. When accumulated ice melts during a warm day, the water pools and has grave potential to destroy the engine.
