Hello everyone, I'm after some help replacing the screen washer pump on my C30 (2008) and was wondering if anyone could help please.

I can get to the pump and fluid reservoir by taking the wheel and inner arch off but then I'm presented with a very complicated set of tubes and screws! I also don't know what pump I should buy to replace the one in there.

Has anyone replaced their washer pump or has any hints on how to do it please? Also does anyone know the part number for the washer pump?

Thanks very much!
