Whilst replacing the carbon brushes in the starter on my bike seemed to cure the problem for a few weeks I now have the "Will I - won't I" pause again on start up. Even when hot! So it's finally new starter time. I find that the range of prices is ridiculous though. On Ebay you can see them from £45 to almost £200 - and I don't recognise a makers name on any of them! I have found a local Auto electrician - in Preston, who advertises on EBay for BMW starters. At least if I know where it came from I can doorstep them if it fails... Trouble is, he wants a part number to give me a price. Is there a way to find what the part number is of my starter without taking the thing off the bike?
