Hi Paul,

Firstly Renault tell us that "All aftersales operations must be performed under very clean conditions and that work should ony be carried out by quailified person/s."
The Fuel filter is located behind the wheel arch liner on the driver's side.
1/To gain access, remove the driver's front wheel.
2/remove the wheel arch liner.
Depending on the vehicle,
DRAIN THE WATER IN THE FUEL FILTER - Drain the water in the fuel filter periodically

1/For filters without a water presence sensor: open the drain plug, let the water flow out, close the plug.

2/ For filters with a water presence sensor: disconnect the water presence sensor offset connector, unclip the water presense sensor connector, loosen the water presence sensor by one turn, let the water flow out,tighten the water presence sensor.

I hope this helps. If in doubt, seek the help of a trained service technician.
