Good day all.

A quick question to all the experts out there. I have just driven home after a short journey and noticed for the first time that when trying to accelerate through 60-70 kph that the whole car starts to vibrate until you back off the gas and just stay at a constant speed. Tried driving in Command Shift mode and no matter what gear you're in, at 60-70 kph the vibration starts again until you back off the gas.

Any body got any ideas, thought it was a misfire to start with but driving in Command Shift mode discounted that idea, engine picks up and revs normally.

I have sneaky feeling this is going to be expensive.
