Headlight relay?
When I switch on the headlight it sometimes doesn't come on, soemtimes I can wait 20 secs or so and it will start working, and sometimes I can see it flickering while driving along. Once on I can generally shake/move the headlight unit with no impact, so I don't think its a loose connection in the unit itself.
I've changed the bulbs and there is no difference, and in any other car I'd be looking to a sticking/faulty relay next but can't seem to locate one - does the R class have a headlight relay?
Any other suggestions?
