Starter motor issue, help!!

Right, my starter motor started sticking when it was really cold, in that it seemed like the solenoid was sticking and it took a few attempts for it to engage the flywheel before starting, then when it got warmer it stopped, so I put it down to the cold. Went to start it today and it started playing up again. It started once after a few tries, then I thought I'd try again and starter motor just turns now, it's not engaging at all.

Any thoughts anyone? If it's any use, I changed a heater hose just before and got water everywhere, but I doubt this would do it would it?

Oh and it's a 200tdi.

Cheers!!

Ok, I've worked out that it's the bendix at fault, looking at the symptoms and researching it. Where can I actually them from?
