So I'm driving down the M23 from the lit to the unlit section and I realise my headlights aren't on. Yet they are set on auto and the dash indicates they are on with no problems. On a hunch I quickly turn the switch round to "off" and all the way back to auto again. Hey presto the lights come on. Few days later I'm sitting behind a black car in traffic and see only ONE headlamp is on. Again, no indication of a problem on the dash display. Same solution solves it. Repeated again today. Anybody got a clue what this is all about and the fix could be???

Try running the lights in manual mode and see if this eliminates the problem which could be the light control module, there have been isolated cases of the stalk switch playing up on other models.

Thanks Steve, I haven't tested it properly in manual mode - I'll do so and report back.
