Jetta wagon tdi clean diesel vehicle was being driven about 35 mph on busy road with full tank of fuel. Vehicle started stumbling and losing power. Within 30 seconds of stumbling vehicle then stalled. Initially was able to be restarted but was stumbling severely and was only able to creep a few feet before stalling. Vehicle was unable to be restarted and had to be towed 23 miles to nearest dealership where the intercooler (charge cooler) was found to have iced up and contain ice and water. This seems to be known issue with the vehicle as vw has a TSB out on the issue. The dealership stated that they actually had another vehicle with the same issue come in the day after ours and last winter had many with this issue. This appears to be a known issue and is clearly a safety issue if it can cause the vehicle to suddenly and unpredictably loose power and stall. Vw TSB # 21 11 06 / 2025464 references this issue.
