Hi all I got an issue with an Audi q7 2014 plate 

the steering wobbles or shakes a little vibration when I go over 70 mph 

I have had tracking and balanced wheels still not right 

Braking is fine as I have had new discs and pads on 

Have you had a diagnostic check to see if any fault codes flag up. Worse case scenario is that it'll be an issue with the steering rack 

Welcome Robi, and thanks for joining. 
Did the alignment people thoroughly check all aspects of the suspension and steering before making their adjustments, or did they simply stick it on the machine? 
When did this wobble occur? - have you had any new tyres on the car before it started? 
Any time tie up with having new discs and pads fitted? 
Are the tyre treads reasonably evenly matched on all four wheels, and are the brands matching - at least on the same axle? 
Kind regards,

Gareth. 

Probably a slight buckle in one of the wheels. Swap the front wheels with the rear wheels and see if it still does it.

Thanks Dave,
