While traveling at night on a 4 lane highway at 70 mph in heavy traffic the vehicle went into limp mode without warning or any symptoms of a power problem. We had to move across four lanes of car and truck traffic while rapidly decelerating. Luck and skill prevailed to avoid a serious and potentially fatal accident. No warning indicators were displayed. Safely in the breakdown lane the vehicle continued an approximately 1300 RPM idle and would move at about 15- 20mph. I stopped the vehicle and the acclerator pedal continued to be unresponsive. I placed the vehicle in neutral with no change in the ability to increase RPM with the accelerator. I shifted back to drive and normal acceleration function returned. We drove another 35-40 minutes without further problems. The next morning the vehicle drove normally and I took it to the VW dealer. Their diagnostic review showed no issues and no malfunctions were detected.
