Fair enough. Not looked into it myself - I had assumed the pump would have its own fuse though, so that could just be pulled?
(thinking a bit further though... it's probably a maxi fuse, yes - so something that Citroen say can only be removed by a Citroen main dealer so maybe that's the reason they don't suggest it...)
