How do I get rid of the 'water in fuel' message on my Jaguar XF?

I recently changed the intercooler on my 2010 Jaguar XF and now I'm getting an intermittent warning message which reads 'water in fuel, consult handbook.' How do I get rid of this message?
The message is not related to the intercooler. It is most likely the sensor fitted to your fuel filter (a known fault). Not a difficult job to do yourself, but if you are going to a garage ask them to change it rather than saying you have a warning message (otherwise they may try and carry out a diagnostic at additional cost to you).
