Do you know what, it's not as silly as it sounds... Just went out there and measured the voltage with nothing running and no key in. 12.27. Seems a bit low to me. Tried to start him - just some horrible noises and a high-speed clicking sound 7 or 8 times after stopping trying for a few seconds. Tried again - same thing - horrible noises (like it's trying to fire but can't) and then when I turn him off again, the clicking is there again. Took the key out and measured the voltage once more - 12.07. So, looks like the battery might be shot! Alas, I am off to see family shortly (have another car so that's Ok!) so can't get to Halfords to get another today - job for tomorow night now, clearly. The only thing I would ask, is it possible that a weak battery could also cause a gear to vanish? I guess anything is possible to be honest - the battery has been in for 3 years now and I have done almost 80,000 miles in that time so maybe it is due a new one... Thanks for the pointer - will let you know how it goes after I replace it tomorow. TMW
