Can anyone tell me how to work the nightheater on my 99 Scania?
Its got a pull out module and I can get it to work, but it only seems to have one setting - MOLTEN ROCK SAHARA INFERNO.
How do I turn it down?
Yeah them modules are bloomin crap aren’t they. Can’t remember how to adjust them sorry, apart from fiddling with the button options. 
Press and hold the top middle, and then press the bottom left. The display changes to a number.
Use the bottom two buttons to adjust the number setting. From 4-6 is usually a comfortable setting.
Then either press the top middle to change the display or simply let it time out.
Simple 
Thanks Kranke . easy eh

No where near as east as the 3-series where you could turn the heat up or down with your eyes shut and or pitch black and still in bed.
