Unknown , The vehicle is a slap shift and I can't put it in sport mode as well when driving I've been in just regular automatic it will shift slow but hard when it's in slap shift it it shifts Hard and when it is in sport mode it will shift fast and hard it's like a jerk it has a very rough idol and sometimes the windshield wiper's will work sometimes they won't and my cruise control does not work and I put my code reader on it and it says $7E8 and $7E9 along with not being able to complete smog test, and it acted like it wanted to die when I was in drive through it has well over half tank gas. Also it seems to be sucking more gas and my miles are going really fait's going really fast like they're not matching what I'm actually driving.

Horn doesn't work on the steering wheel. Air bag light frequently fails to initially illuminate when first starting the car. Cruise control does not work. One would believe there is a clock spring issue. How my specific jetta was not included in the original recall of clock springs is concerning.

I was cruising at 60 MPH this morning when the glow-plug warning light began to flash and the cruise control was shut off immediately causing an unexpected deceleration. I pulled into the emergency lane and the engine shut off once I came to a stop. The engine would not restart and the glow-plug light was joined with the check engine light. I had it towed to my mechanic who read the computer codes as "low fuel pressure to the injectors". He looked into the fuel filter and found metal shaving. He stated those shaving point to a complete failure of the high pressure fuel pump (hpfp). I owned this car for only two weeks and, based on volkswagen's reputation and the reputation of the tdi diesel engine I expected to own this car for years. The repair costs are now estimated to be half the purchase price I paid less than a month ago.

Approximately a year ago, my engine began to give a clear sense of the car shuddering or rocking back and forth. While sometimes the feeling would occur even when stopped at a light, the vast majority of the time this occurred while I was driving at consistent low speeds. In almost all cases, I was attempting to maintain a consistent speed around either 13pmh or 30 MPH. Eventually, I found the rocking motion very easy to reproduce. I'd set the car to 30 MPH via cruise control and drive down a straight road with very slight upward and downward slopes. While it happens even on flat ground, I found that a slight decline is most likely to reproduce the feeling. My best guess is that there's something about the way the fuel supply system/transmission is trying to determine whether or not diesel needs to be supplied to the engine. The fuel supply system seems to almost cut out because giving diesel would produce a speed too high, and then it comes back on suddenly, because giving it no diesel would cause the car to slow too much. While sometimes this is simply a nuisance, I have had on many occasions felt that it was a genuine safety hazard since I couldn't predict how the engine would react. This in combination with overly strong engine break when letting off of the accelerator and delayed acceleration when stepping on the peddle that can cause inconsistencies and safety hazards when maneuvering in stop and go traffic on the highway. I've mentioned this problem every single time I've taken my car in for it's regularly scheduled maintenance. The vehicle has a diesel dsg engine, and as I've been told by service technicians and representatives, some of the things like strong engine breaking are associated with this type of engine. However, the car's rocking motion certainly goes beyond anything that could realistically be considered normal and safe.
