Water drainage from the fuel pre-filter (if present)
The high risk of refuelling with fuel that is polluted by foreign bodies
and water makes it advisable to carry out this control every time you
refuel.
Proceed with the engine stopped.
Place a container under the pre-filter to collect the fluid.
Unscrew the tap plug (3) in the bottom part of the filter; in some
lay-outs the plug includes a sensor to detect the presence of water
in the diesel.
Drain off liquid until only “diesel” can be seen.
Close the plug again, tightening it completely by hand.
Dispose of the drained fluids according to current requirements.
