I am experiencing sudden forceful jerk intermittently when my Tuareg V8 2004 model SUV is in motion. What is the cause and solution?

Most likely it has something to do with the transmission and the transmission shifting hard. Does it happen when you accelerate and shift or is it random.

Touaregs are infamous for haveing problems with the Prop shaft berring. Also you couls reset the driver adaptive gas pedal.With your foot all the way on the gas, Turn the key on without starting the motor. Keep gas pressed for 10 secs. then turn key off. The ECM adapts to your style of driving.

Ok, will sound strange, but I will discribe my experience and solution. I would drive along at any speed and the car would start to spudder and loose power. The all of a sudden it was like the afterburners Turner on and we took off like a shot. Dealer did not know what it was. I found the fuel rail pressure was dropping from 50+, where it should be, to below 20. Then jump back to the normal mark. The touareg has 2 fule tanks and they straddle the driveshaft. Thus 2 fuel pumps, the primary pump is on the passenger side, but both will feed the rail also. The pumps were fine, there is a screen on the bottom of the pumps that was dirty and restrictiNG flow, the tranfer pump would compensate when the rail pressure droped too far. Removed the pump cleaned the screen and it was all better. No new pumps!

Why is my 2006 touareg not moving off immediately when you floor the gas pedal

Replace the fuel pumps, left and right. Also replace the drivers side fuel pump flange. Replace both fuel pump flang o-rings. The drivers side flange is also the fuel filter. I work on my own Touareg. My 06 4.2 Touareg would fall off then catch its self. Also be sure to keep the gas tank 3/4 full or better. The gas will all go to one side and one pump will not have fuel. The passager pump is start up and extra fuel when demanded by the driver to accelerate. Always keep that tank full!
