Help - Shuddering at high speeds A5 V6 Quattro Diesel 2014

[SuperSeven]

I Have an A5 3.0 Tdi Quattro 2014, there is a shuddering going on that I only notice or is only there when going 65 mph+. I put it into a garage called farmers and explained that it happens for around 2 seconds then stops for a second and repeats at high speeds, they checked it out and couldn't fault it, has anyone had this issue before or know what it could be?

The car in question for you all.
