Hva betyr feilkoden?
The heater control module has registered an internal fault in the monitoring of its processor, a so-called watchdog or safety fault. The heater is switched off when the fault code is set, and if you start it again it makes a new start attempt. The fault comes from the control module itself.
Mulige årsaker

Hva du kan gjøre
- 1Start the heater again and check whether it runs normally. It may be a temporary fault that does not return.
- 2Check that the fuses for the heater are intact. Look in the car's manual to find where they are.
- 3If the fault is lasting, have a workshop download the latest software to the heater and then check that the fault has cleared.
- 4If the fault returns, have a workshop replace the heater control module.
