The water in fuel warning occurred several times when driving about in Saturday's rain, usually each time after the right front wheel splashed in a puddle. Hopefully water is getting to the sensor electrical connector rather than in the fuel so need to have a peek around the filter that's below the drivers seat or thereabouts.

Might have to add it to the list of things to be checked when next at the dealers, along with the red triangle without a message that went away with a restart at 80 kph.
