Tonight I've jacked it up and turned the wheels around, looked for something loose but found nothing much apart from a bit of bearing play. Is there a correct way of adjusting the bearings rather than the nip up a bit method which I found here

I recently came from a VW/Audi/Skoda forum which would have had a torque setting for emptying the ash tray, so trial and error just doesn't feel right.
Does the vibration come through the brake pedal when braking? Warped brake disc.
Have you checked to make sure you don't have a stone lodged in the tyre tread?
Is the wheel rim square with the hub, i.e. no debris preventing the wheel to mate with the hub square?
Have you locked the front wheels recently under heavy braking and therefore flat spotted the tyre? Unlikely with ABS but still possible.
Failing all of the above, try another tyre fitting centre.
