Vehicle was going at 25 mph when it started losing power. It stopped barely few feet after the intersection. Engine would not start. Vehicle was towed away to the nearest VW dealership. After investigation dealership says that they found traces of gasoline in the fuel pump and gasoline has destroyed the fuel system. I showed them my last three receipts as proof that I always put diesel in the vehicle. Car is at the dealership since 01-Aug-2011. They said they have to replace the whole system. Initially they have quoted about $4800 + labor but later on they agreed to fix it under warranty, car is only 18 months old and has 1800 miles. I am concerned that this may happen again as I still would end up going to the same diesel stations for filling and if they are contaminated as dealer says I may end up with a dead engine again.

Dead pedal - hesitation - stalling. Absolutely no throttle response when trying to pull out into traffic. You press the pedal and there is nothing there. Stop and go traffic on the expressway or stopping at an intersection the car stalls. Also have experienced surging at highway speed as if the fuel supply is cutting out. We recently returned from a trip to portsmouth nh. We were in six lanes of stop and go traffic on I-95 and the car kept stalling. When you would depress the gas pedal to continue moving there is no throttle response. We parked in the portsmouth municipal garage. As we ascended through the garage looking for a parking space [incline position] about 5 mph, there was no throttle response. The car would not move. I had to continue to feather the pedal to pull into a parking space. We now have 20K miles on the car and have had the car looked at 6 times at the local VW dealer with no fix. The car has serious throttle issues and has become dangerous to drive. Please note to numerous to mention VW tdi hesitation issues on many web forums. Someone is likely to get seriously injured or killed with this problem that VW must know about. Please advise !!!!!

This vehicle has experienced continual problems with engine shuddering and stalling. Mostly, while in 2nd, 3rd or 4th gear, early on into a trip the engine will suddenly decelerate and in some case stall out completely. It is as if there is a sudden loss in fuel getting to the engine. This started soon after purchasing the car. It has been into the dealership numerous (6 or 7) times for this warranty issue, including extended stay periods of seven and ten days. First they faulted my fuel, then they replaced the fuel pump, then they have done other work and replaced components, but claim they can not make the car fail as I have reported. They claim to have alerted VW and had a VW technical advisers look at this car. They refuse to do any additional warranty work on the car for this issue since they can not diagnose it. I have kept a log of these failures since my last servicing. Between 10/22/2010 to 3/12/2011 this vehicle has had 19 of these failure events. They usually occur when the outside air temperature is above 32 degrees Fahrenheit. The vehicle is still under warranty (28,500 miles on the odometer). I am finding other owners experiencing similar problems. Please help.
