Hi all... Unfortunately i sold my vr6 to help buy a house, miss it loads!!!!! But i never had the vibration cured.. New plugs, leads, had timing checked, belts, mounting all electrics and so on by vw and specialists but no cure.. The v dubs specialist did say it could be a worn crankshaft bearing which was £££'s to get checked/replaced so i left it, i couldn't fault the car otherwise.. good luck...
