Does the Roomster have a low windscreen washer warning? The handbook suggests it does but mine just ran dry without any indicator coming on in the maxidot display.

Nope, it doesn't have this feature.

Isn't there a warning if headlamp washers are fitted, but not if you just have windscreen washers? The Fabia certainly mentions one, but an earlier forum thread suggested the above.

Actually it will if there are headlamp washers are fitted as this will have the 5l tank. Not sure if headlamp washers are available in the UK

Case solved, thank you!
