      cockpit display lights?
      It, of course turns on when I manually have the headlights on or at night when switch is in usual 'auto' position. I'd like it on all the time.

      Hi,
      It is located on the top left corner of the central display.

      On other VWs ~2005> you can do it via a recode of instruments in VCDS. Maybe that is worth a look too?

      I own a 2009 model and my lights, numbers on speedo etc. are on all the time.
      Just takes a few moments after startup for them to get brighter.
      They are even on when I switch off my lights.

      The manual indicates that if the switch is turned to AHC the dash lights will turn on when entering a tunnel but not where the sensor is ??

      I confess I thought there was only one sensor and that turned on both the exterior lights and the instrument lights - ie they are not controlled separately... not sure if I'm right - but I was pretty sure till I read this thread.

      The sensor for the exterior lights is, I believe, in the centre top of the windscreen- ie mounted in the trim just between the windscreen and the rear view mirror.

      Do you mean INTERIOR lights?
      Isn't that where the rain sensor is?

      Well, clearly you can't take anything I think as authoritative... as Chris has shown.. but I did think that the photosensor to turn the driving lights on was in the same binnacle as the rain sensor... but it could be I'm mistaken.

      Ron,
      If by "cockpit display lights" you mean the instruments backlight, unfortunately on cars of your vintage and mine they only go on when the headlights are on. I recall years ago several owners complained about the instruments being hard to read during daytime under certain conditions, and there should be a thread here somewhere about this issue.

      I think that the sensor that Chris has highlighted is solely for the purpose of adjusting the brightness of the infotainment screen depending on how light or dark the interior is.

      I think Stefan is right.

      But just in case I thought the other light sensor was just an an ordinary light sensor, the SSP explains it's more complicated than that.

      So then I can presume I can not fool the sensor?
      The confusing part I always thought I had the interior cockpit illuminated before I had my 80K service last week?

      Since the sensors do so many functions (like under-bridge detection, rain sensing wiper control etc) it's probably going to confuse things if one or more are blanked off.

      The instrument lighting is controlled by the Onboard Power Supply control module - maybe there's some kind of coding in that? But it probably takes a light signal from one of the four light sensors (the third and fourth are on the back and front of the rear view mirror). So maybe they also have related coding.

      The windscreen light detection is an optional extra - maybe it got re-coded during service, especially if they flattened or disconnected the LH battery.

      Chris
