Replaced with a febi 26259 from Amazon. Had to take the inner wing guard off to get to it ,lots of torx screw to remove some underneath in bumper and under engine cover.

Wash tank grommet I bought from e-bay    vw/audi 431955465A turned out to be wrong far to big. But things seem OK without it , but would be grateful if anyone knows correct part number as a standby.

Glad the screen wash tank is not leaking as bumper would have had to come off to get to it for replacement!

I also found this video on how to replace the bottle/tank if your unlucky and this has failed. I dare say bumper removal on Roomster will be slightly different.

Looks like correct grommet part number for pump is 443 955 465 ,but old one is holding up.

But would have been nice to have installed new with pump.
