Thanks Charlie for taking the time to explain the reasoning on getting this fault diagnosed correctly

The Evoque is in daily use by by daughter who loves it.
So yes reading the Haldex Repair guys web site they certainly know what they are doing.
So later today, Rod's is going to pop the car over to my workshop and get it over the pit.
We are simply going the pull the plug off the Haldex ECU and test drive it (ignoring dash lights etc)

If the vibration remains then it's more than likely to be a drive shaft on it's way out.
Rod favours the NSF
BUT if the vibration goes then we can focus on the Haldex. It's the Gen 4 model.
And start with an oil and filter change and go from there
