Despite being full, the washer bottle low level warning light has come on in my 2010 vRS. I'm guessing there's some sort of sensor that could have failed. I'd appreciate any thoughts on this, particularly as car is due MoT soon. Thanks in advance.

The sensor is at the bottom of the washer bottle, see here for pictures...

Thanks silver1011, that's great. At least access to sensor looks relatively straightforward and parts, if needed, not too expensive. Just need to get through some screenwash now!
