I own a 2014 Jetta TDI. I have been very satisfied with this car until about a year ago. On backing out of a parking space, the car started to jerk and lost power to the extent I thought it was going to stall. As fast as the problem started it corrected itself and had no further issues for a couple of months. The same thing happened again so I took it to the dealer. $100. later I was no further ahead. The Service Manager said the car was scanned and showed no faults. Was told a tech spent about an hour on the problem driving the car at various speeds both on their lot as well as on the highway but could not find any issues. A friend suggested I add Stanadyne to the fuel which I did. The the car definitely performed better with no sign of the jerking/hesitation. After using the additive for a few months I stopped as I was curious what would happen. After a few months I noticed a slight hesitation from time to time but nothing as dramatic as before. I had the car scanned once again but still is not showing any faults. Any suggestions?

IMO a good Additive is a must with todays limited lubrication diesel. Always start with the obvious. Injectors need cleaning? Fuel filter?

After the first incident, I replaced both the fuel filter and air filter. The problem still persisted. As this is not a regular occurrence could it be an injector incident. If so, is there an additive or should the injector be removed and cleaned?

Try Techtron D, some people, including myself, notice an improvement
