Which washer pump is which?

[Brian J]

My 182 screen wash is working fine, but the headlight wash has packed up.
The pump runs as it should, so I need to investigate, but which washer pump is which? I’d rather only suspect and test the bad one and leave the hood one well alone!!

Can anyone please tell me is it the outer or inner pump that provides the headlight wash?

Here's a schematic for you as I can't remember myself off the top of my head. I think it's the one nearest the filler cap. It's a while since i did mine. Part numbers are also included.

Thanks. Even Renault don’t seem to make the diagram easy!
I will take it apart and update this post.

NO.4 in the schematic is the one you're after and that's closest to the filler cap.

I can indeed confirm it is the inner pump.
