In 4 month I've had to replace the turbo diesel sensor valve brakes discs propshaft bearings and now I have been told that the gearbox transfer box or drive shaft may have gone theres a really bad vibration from drivers side which shakes the whole car violently when i go over 40mph I'm at the end of my tether wish id never bought the dam thing.
I had a really bad vibration after repairing the VCU on mine. Turned out the damper was causing it and after turning it round one bolt hole (a ten minute job) the vibration was gone. I had noticed the damper wasn't perfectly centred while the VCU was on the bench so wasn't surprised it caused a problem. I was more surprised the vibration was gone after turning it and several peeps on here still don't believe me but it is true.
If you want to give it a try put two wheels on one side onto blocks or similar, crawl under with a socket, (15 or 17mm I think) undo the three bolts, rotate the damper one hole and put the bolts back in. It mightn't do anything for you or it might fix it. You'll never know unless you try.
