Hi fellas new owner of a b7 2.0tdi cabby sline got a problem with it at the moment. im getting vibration through the chassis when hitting 70mph +. ive had it checked over mechanically and nothing obvious. So had the 19" sline wheels checked to find the rear wheels were both slightly buckled, so ive taken them in to be checked and was given some temporarys on the rear by the refurbers whilst they straghteded mine. On my way home from there with to good rear wheels now the vibration is still there!?!?! anyone else had anythong like this? Also want to retrofit cruise control into mine. Easy job or to much hard work?
