Mine had this problem, on the picture that acf818 has posted that assembley is held on buy a sheer bolt, it had come loss so i got a new one from vw for a couple of quid, when you tighten it up you keep going until the bolt bit breaks off, i had to change the hole assembly in the picture but couldn't get the splined bit off the rack, will be trying that again soon, check that sheer bolt mate, opposite side to the ignition barrel Paul
