yeah same here bt my mk 4 knob was tight enough to just push down over the threads nd give a bit of a thump nd it stays tight, next problem is the mk4 gaitor isnt big enough, it fits roung the surround great but as soon as u push the knob forward to change gear it pulls off, cutting the gearstick down doesnt wrk either cos its the distance between say 1st n 2nd thats the problem, hard to understand untill u try and youl c what i mean.
