Hi

The lower dashboard light, not the triangle one higher up, that lights up fine. Reading the manual the 4matic light should come on with the ignition and then turnoff after the engine has started.

I read on another forum that a tech disabled the 4matic by removing the bulb?

What I am trying to work out is what other factors could cause the 4matic symbol not to light up other than a blown bulb, eg OVP, or 4matic ECU.
