Engine Problems of Volkswagen Jetta Sportwagen

I pulled into a parking spot , took my foot off the gas pedal to coast in and applied the brake (approx 3 to 4 mph). The engine revved and accelerated. The car lurched forward. I pushed the brake pedal as hard as I could. The car moved approx 6 feet and over a 6 inch curb. Suddenly the engine returned to normal revs. Luckily there was only lawn in front of me or I would have done significant damage. Strangely the car radio changed stations at the exact same time of the acceleration. The engine type is the vw diesel tdi with automatic transmission.

2010 Jetta Sportwagen tdi; vehicle lost power but continued running. Dash warning lights(glow plug lamp flashing) were illuminated. Dealer stated fuel contamination. Fuel tests, by an actual fuel lab, show fuel in the system met all astm standards for diesel fuel oils. Premature failure of the materials which compose the fuel filter/ water seperator housing were apparent however they were attributed to "water" in the fuel which is ironic being that it is a fuel filter/water separator. The hpfp ( high pressure fuel pump ) was most probably the root cuase of the entire failure. Vw's resolution was to involve my insurance as the method of payment to replace the entire fuel system(tank to injectors). I can not however use the insurance to complete this claim as it would be fruad knowing that the actual problem is the responsibility of Volkswagen.

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.

I own a 2009 Volkswagen jetta tdi sportwagen. It has approximately 8,000 miles on the odometer. I believe that this car has a serious design flaw, which creates a very unsafe driving condition. On a daily basis, I experience a situation in which I am waiting at a stop light to turn left, and when I depress the pedal to accelerate through the intersection, the car moves a few feet (into traffic) and then stops altogether. After pressing the pedal all the way to the floor for 2-3 seconds, it reluctantly starts moving again, and I observe a huge cloud of white vapor pouring out of the tailpipe as the car takes off again. My fear is that I, or someone else, will be unable to clear an intersection in a dangerous (or otherwise normal) situation and will be involved in a head-on or t-bone accident that will cause serious injury and/or death. The car displays no error codes, and otherwise drives perfectly normal.
