Good Morning,

I have a problem with the Engine Pre-Heater Part (M18 code), of my W203 220cdi (year 2004), it is possible work without that, how can be disabled in car settings ?

Thanks

You could live without one - not all diesels have them and the one in our landrover was disconnected for a while recently at a recall, but in cold climates it will extend the warm up times considerably.
I'm not aware of a menu way to turn it off (other may though) but you could simply disconnect the power lead or maybe even just pull the fuse - depending on what else is on it.
why do you want to disable it?

Thats because it was in short-circuit, and discharge battery if is connected.
The Mechanic disconnect it and turn de engine on, but it works "unsicronized"...maybe it needs that module for some digital resistence.

Thanks for everything
Pedro
