The electrical supply to the water heater unit can shut off too soon when the vehicle is stopped.
Fuel can therefore remain in the heater, producing smoke and fuel leakage. Moreover, the information about atmospheric pressure sent by the BSI to the water heating unit is incorrect, so the unit is unable to operate. The unburnt fuel may remain inside the unit and may produce smoke when next activated. Fuel may potentially leak, increasing the risk of fire.
The Citroen C5 Aircross vehicles affected by this recall were manufactured between 20 June 2018 and 11 October 2021.
