my 2010 Q7 3.0 TDI CASA engine and KMB tranny only 45k miles on clock.last Sunday during a ride i just kick down to play lil bit but car gave me very heavily jerk i stop the car and look underneath and engine compartment but find nothing wrong next day i took the car to one of my friend who have scanner in his garage but find no fault in gearbox control unit so the conclusion is when i accelerate normal the car runs fine in each gear and no jolt at all but as i kick down the pedal there is heavy jolt in each and every gear.any feedback greatly appreciated.

Regards shazoo
