When I was doing one of my many dash top removals, I noticed that when the light switch was disconnected the lights came on

So I can only conclude that in true over complicating Range Rover fashion the lights are on all the time and the switch turns them off.... Rather than the more conventional way of doing things where the lights are off and the switch turns them on

So, if it's not just my car that's been wired up the wrong way round, then it could be a dodgy switch

That's done deliberately so that if the light switch fails you have some lights, they are canbus controlled so difficult to hotwire them on if the switch fails...  Pete

Just to reassure you, I found that when I disconnected my light switch the sidelights came on. No auto lights.

could have sworn that the whole shooting match came on in mine

Anyhow it ain't auto ...... But I did some digging and it would appear that Matt Stevenson (or Mr Mod as I prefer to call him ) was looking in to this on another site Deserter And it would appear that you can fit auto lights, but you have to change the rain sensor, LCM and light switch for a different BMW type but there is no rewiring involved

And just to be really helpful I didn't save the page, and I couldn't be seen to be promoting another forum, so suffice it to say if you were to google auto head lights l322 and look for a link a bit like _ang__over.net you wouldn't be far wrong....

OR

alternatively pm Matt and ask if it was ever perfected  Yesterday I couldn't spell Engineer... Today I are one!

my car is currently back with the supplying dealer, I will have to check all the lights when back, will cover the windscreen take it from there

When I had the rain sensor off yesterday, I came across this in the sensor together with what should be, I expect, a matching hole in the screen mask:

Note the small round red window in the sensor.

I wouldn't bet on it Bud, manufacturers have a nasty habit of all using the same parts with different stickers on them.. chances are they are all Bosch or Siemens.. And Ford didn't change that much from the BMW build when it came to the body.. the wiper relay is still a BMW one up to 2009, I believe that the wipers are the same.. and that is just for starters... I think they only changed bit that were easy to swap over or parts which gave them a big saving in costs, like going to the MOST stereo system.. as they didn't change the shape it sort of makes sense to stick with the same screens and sensors as BMW have already done the leg work, and it would probably cost more to change the screen mask and the BCM / wiring than pay the extra to BMW's suppliers for the original bits.

I don't think that the door locks changed either.. Yesterday I couldn't spell Engineer... Today I are one!

My early 2005 has auto lights - I love them. The FF is the crossover year, pre-facelift, but with the BMW touchscreen SatNav. I've only once left the lights on after having to turn the switch to 'on' in order to use the fog-lights!  2005 L322 Tonga Green 4.4l BMW Engine with Touchscreen
