During moderate acceleration, engine cuts power, epc light and check engine light comes on. Vehicle goes into limp mode, and engine will not turn more than 3000 RPM, and has no power to accelerate. Engine develops misfires and idles very roughly. Engine may stall. Turning key off and back on does not remedy the problem. Disconnecting the battery will turn the epc and check engine lights off, but under next moderate acceleration, epc and check engine lights come back on, and problems come back. Check engine dtc codes range from misfires to system too lean and air intake leaks, and for accelerator/throttle position sensor b malfunctions. These problems have happened multiple times in traffic on the interstate and in the city. The vehicle has stalled at stop signs and traffic lights. It has also stalled during acceleration. This problem started happening on august 6th 2019 and has continued to happen.

Vehicle stalls sporadically when moving slow or at a complete stop. Vehicle also experiences rough idle sporadically. The vehicle so far has only stalled when the car is warmed. The rough idle happens both when the car is cold and warmed. This has happened since the vehicle had 40 miles and had continued now that the vehicle has 2000 miles.

During street and highway driving, the engine stalls after the vehicle is brought to a complete stop with clutch depressed and/or transmission in neutral. Occurs with engine at operating temperature irrespective of initial speed or engaged gear prior to commencement of braking and deceleration. Immediately prior to the stall, the engine runs rough or seems to be misfiring for one or two seconds. Once the first event occurs, it will then repeat 25-50% of the time the vehicle is decelerated to a stop.

On jan 29, 2019, I purchased the car new, from a dealer in south florida with approximately 13 miles on the odometer. The vehicle has a manual transmission. After driving the vehicle less than one mile from the dealer, the vehicle stalled at a stop light. At the time, the vehicle was stationary, in neutral, with the clutch petal in the fully raised position, and had been idling for about 10 minutes prior to the occurrence. I restarted the car and within a few seconds, the car stalled again under the same conditions. I returned to the dealer to have the car inspected. On the short drive back, the car stalled 3 additional times under similar circumstances. The dealer couldn't find any explanation for the stalling. Unable to replicate the issue, I drove the car for approximately 150 more miles. On february 1, 2019, the issue recurred, again at a stoplight under similar conditions. I can assert, with confidence, that none of the occurrences were due to driver error. Additionally, the car is not equipped with an auto-start system (which could have explained the behavior). Although the issue has not resurfaced since then (now about 3000 miles later), the car exhibits a rough idle, especially when started cold. There is no visible fluctuation in the rpms on the tachometer, but I can audibly hear and feel the engine "skipping". The car build date was october 2018.

Ongoing engine misfire issues. After 3 visits to dealership and replacement of coils, fuses, relays, etc, root cause determined to be a short between the after run coolant pump which causes a voltage draw and confuses the ECM. After talking with vw technician, I learned that this same exact part on audi vehicles is under a safety recall for the shorting issue that my pump is having because the short can cause fires. However, the vw part is not under recall. My family could have been put in grave danger because this part is in my car and has not been recalled. In addition, even though the part has failed, vw will not compensate me for the repair, so I have no choice but to pay $500 out of pocket to fix a safety hazard in my vehicle. For reference, audi recall number is 18v229000.

Engine is misfiring at 84k miles causing the car to need a whole new engine rebuild. I have gotten the vehicle serviced regularly to prevent such issue. Fuel injectors, intake manifold gaskets, and intake manifold were replaced on 2/21/18 and I also had a carbon cleaning this day as well at 79k. All four spark plugs, and ignition coils have also been replaced. With all these preventative repairs I should not be having to replace my engine only 5k miles are all those repairs.

I was driving in traffic when the engine started to run rough and loud. I had to pull over and turn it off. When trying to turn it back on it started up and continued to run rough. I had the vehicle towed to the shop. When they looked at it they told me the engine needed to be replaced due to the timing chain tensioner failing. When I asked about when I was supposed to have this service done they told me its not listed in the owners manuel or at any service interval up to this point. The part is not on any list of service for the car yet failed at 93k miles. Vw should issue a recall for this problem because they didn't report it to me as something that could break. I was told when I bought the car that the timing chain and tensioner should last the life of the vehicle which should be much higher then 93k. This is a common issue in all vw tsi engines and can happen as early as 40k, vw needs to fix this and warn existing customers.

For several weeks, I noticed occasional misfires upon startup and acceleration. Then, the vehicle began running loudly and consuming a lot of oil. The vehicle also shuddered while driving. One morning, the car shuddered and bucked while I attempted to start it, and ultimately failed to start after several attempts. The engine light illuminated. This is not a battery issue; the battery is only a few months old and was tested in the past few weeks (holds charge at 100%). I have had the car towed to two mechanics and the problem was diagnosed as a timing chain tensioner failure leading to catastrophic engine failure. According to the first mechanic, the entire engine needs to be replaced for approximately $4500. According to the second mechanic, the timing chain tensioner needs replacing and the top half of the engine needs to be repaired, leading to a quote of $2800 for repair. The mechanic stated to me that he has already performed approximately 8 of these repairs on volkswagens in the last year and directed me to investigate a pending new jersey lawsuit against volkswagen for the same issue. This appears to be a common complaint. If my engine had failed while at speed on a roadway it would have been extremely dangerous.
