9 modelsS60 (2011–), S80 (2007–), V40 (2013–), V40 Cross Country (2013–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
What does this fault code mean?
The flame goes out repeatedly during warm-up, in a way that is not permitted when the heater runs at half speed. The control module then switches the heater off. The fault may be caused by fuel problems such as a low level, a leak or air in the fuel, a blocked intake or exhaust system, or a dirty or damaged flame sensor.
Possible causes
- Car parked on a steep slope
- Low fuel level
- Leak, air or a blocked fuel system
- Damaged fuel pump
- Blocked intake or exhaust system
- Sooty or damaged flame sensor
What you can do
- 1Park the vehicle on level ground and try starting the heater again. A steep slope can make the flame go out.
- 2Check the fuel level in the tank and top up if it is low.
- 3Use gloves and safety goggles, as fuel can spill. With the ignition off, check the fuel lines for leaks.
- 4Inspect the air inlet and the exhaust pipe for obstructions and clear them. Tighten or replace a leaking clamp.
- 5Look at the flame sensor. If it is sooty or damaged, a workshop can clean or replace it.
- 6If the fault remains after these checks, have a workshop check the fuel pump and the fuel supply.
