Graham, I too have a screenwash pump problem on my X150 2012 XKR and the first thing I want to do is check the Screenwash pump fuse. I can only find one fuse F4 for Powerwash. I assume that must do both windscreen and headlamp?

 

Glen,

I can only see one fuse for the wash/wipe system. If both windscreen and headlamp washer pumps are off, it's likely to be the fuse although the headlamp wash does also go through a relay. If only one is off, it's likely to be the pump itself failed.
