W209 headlamps stay on

[IforG]

My CLK cab headlamps will not turn off whatever I do. The rotary switch works for front and rear fog lights and the parking light function works at it should. Even with the switch in the off position, dipped headlamps shine brightly, even in full sunshine.
Any ideas, guys, please?

Check out the steering wheel menu options. I think there's one there to set headlamps on all the time (think it is required for Sweden).

I assume they go off when ignition off, if not, that's quite a different fault.

Yes. There's a setting in the dash menu for them to be on all the time.

Hi Ted and Codger49.

You guys are brilliant!! I must have inadvertently changed this a couple of days ago when I was re-setting the clock.

Many, many thanks for your help.
