Problems in the cold

[scottydee]

This morning when I started my car (W204 C250 coupe) The passenger airbag warning came on and the parking brake warning. My headlights also came on. The lights would not switch onto sidelights when I tried, so I switched off and re-started, and it was ok.
It then did it again - the command screen went off then came back on with the headlights activating, but wouldn't switch off again.

It's happened a couple of times before, but only when cold!

Any ideas?

Inspect main battery for voltage condition would be my first check.

Thanks - I'll have a look - I also noticed that the ECO light wasn't on.

Check the auxiliary battery, if that’s no good, the stupid eco doesn’t work, which is a bonus imho.

Good point - it's the first thing I switch off when I get in!

Pull the 7.5 amp fuse on top of the battery , no more button pressing.

Or remove the 5Kg and use as a paper weight to permanently disable Stop Strain .
