Now this is severely off topic, but I have been scouring the UK for an answer for weeks. Maybe you guys over the pond can help. I have a Citroen Picasso 2.0Hdi.and I need to replace the starter motor. It is the number of teeth on the pinion gear that is the issue. Suppliers are specifying varying numbers- 9,12 ( I assume this means 9,10,11 or 12) 10,12 11 10 I would have thought that the teeth count was specific, but suppliers are saying it's variable. This makes no sense to me.
