Worked for a while but odo has stopped again (speedo still fine if a little jittery at times).
I think I'll need to do it all again but want to buy a replacement drive cog so i don't ever have this again! I think perhaps the crack in mine has progressed.
(As an aside, I did replace my front wiper motor afterwards which involved moving the speedo cable around a lot to gain access - not sure if this did some damage…?)
Anyone know where to buy a replacement cog or any other advice?

If so, it's #5 (171 957 821 B) on the schematic linked to below -

The drives are coloured intentionally, there's a cream coloured one too… each denotes the gearing ratio for your particular application, so stick with the one you originally had.
Before you start to take anything apart, have a good look at how it's attached first, the drive pulls off but there's a little circlip (#6) holding it that can be a pain to remove.
If you lose it, it's not that easy to replace, I believe even new speedo cables don't include them meaning you have to reuse your existing one.
If your drive is failing / cracked, be careful extracting it in case any parts fall into the bell housing.

I went to look for a pic of it and actually found a helpful post on this very forum (couldn't find it before!):

Does anyone in the UK/Europe know of a supplier of a similar part?
I did look on ebay but they're about £50 inc postage - and out of stock anyway…
(I did think about buying an old speedo, taking it apart and getting the gear from that - but no guarantee it won't be an old, cracked gear too.)
