If none of these checks reveal any faults:
–Replace the water detection sensor (see MR 364, Mechanics, 13A, Fuel supply).
–Clear the fault.
–Carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds,
to confirm the repair.
Note:
if the level of water in the fuel filter unit is lower than the sensor electrodes, certain driving conditions (on a bend,
hill) may causethe injection warning light to light up erratically.
