Automatic Headlights

[Old Mosher]

Hi. On my 2001 Hdi 2.2 exclusive the light level needed to turn the head lights on automatically is a little on the low side, ie its a bit too dark for the lights to be off. Can this be adjusted in some way?

My C5 has the same problem. They're always slow to switch on and also slow to switch off. Don't know if it's adjustable. Maybe it is through a Lexia.

have you tryed cleaning the sensor it behind the rear view mirror onto the windscreen. Seen this a few times on the pug 406s. think the demist setting tends to put a film over crap on the sensor after a few years

Had a look at the light censure, couldn't find anything fogging its view of the glass so I cleaned it anyway re assembled it. No joy. So as a stop gap solution I made a light filter for it by slipping two layers of antistatic bag (the silver translucent stuff that electronic or computer parts are shipped in) under the sensers uv filter. So far so good, its switches on and of well.
