Water in diesel fuel filter

(Multijet versions - amber)

Turning the ignition key to MAR the warning light turns on, but it should go off after few seconds. The warning light turns on when there is water in the diesel fuel filter. On certain versions the warning light turns on and the display shows a dedicated message.

The presence of water in the fuel circuit may cause serious damage to the entire injection system and cause irregular engine operation. If the warning light turns on (on certain versions together with the message on the display) contact Fiat Dealership as soon as possible to have the system relieved.

If the above indications come on immediately after refueling, water has probably been poured into the tank: turn the engine off immediately and contact Fiat Dealership.
