I managed to shear off the bolt that secures the positive battery lead onto the terminal today - it'd been tight in both directions for a while and today it just went...
Being a weekend and no dealerships open, searching online produced some bad news: it seems BMW don't sell the bolt seperately but want to relieve you of much more £££ to buy it as part of a new cable. Info was taken from THIS THREAD on another forum. There's a picture of the bolt in question on that link.
So, rather than chance it with Halfords who I doubt would have it anyway, I modified my sheared bolt as follows:
- cut the bolt stem off with a dremel flush with the bottom
- drill a hole through the bottom piece
- stick a similarly sized nut/bolt on it

Now fitted and seems to be just as secure as before
Total cost: £0, plus a burnt finger and thumb after underestimating the heat produced by a Dremmel
