Well officially the docs say 72 ,but there is so very much not 72 about it that I'm on a shakey peg trying to define it ,see I never really noticed whether there was a steering lock ,but as I am once again pre mot-ing it ,was wondering the above and really ,can a steering lock if fitted ,simply stop working ?
Yes it can stop working - mine did that just last week then spookily enough started working again yesterday. It is possibly just sticking or not engaging due to misalignment.
