Title: Delay with Auto Lights coming on?
Post by: adekil on 25 November 2014, 17:41
I've not noticed this before, especially with the lighter days/evenings but tonight when switching on the engine, the front headlights took a good 5 or 6 seconds to come on and there was no calibration taking place, the lights just came on in position.

After I got home, switched off the engine and back on again and the lights came on immediately along with the calibration.

Anyone else see this before or is this sometimes the case that the light sensor hasn't kicked in for some reason?

P.S Lights are always set to Auto.

Hey,

I also noticed the lights taking a while to come on sometimes after getting into the car, can't say I noticed if the calibration did its thing or not, will keep an eye on it. Hopefully it's not a problem.

Cheers,
Phil

You can set the lights to come on "early" instead of "normal"... on normal it can take a few seconds for the lights to come on (light sensor may still be running self check).

I would suspect it does the 'calibration' (actually it is just an initialisation) on start up regardless of whether lights are on or not.

Are you talking about the levelling? with the wiring of motor noises?

Good point, maybe they do their levelling thing before the lights actually come on.

Mine whir randomly and sometime I have driven off down the road, be stationary behind someone and noticed they are moving up and down. A flick of the adjustment wheel and they stop doing it.

What adjustment wheel are you talking about?
Only halogens have the electric (manual) adjustment for height, xenons constantly level automatically.

Lights are set to come on early (leaving home function I think its called) when unlocking but this did not happen this time when returning to the car and unlocking; but can honestly never remember ever starting the engine in the dark and having no lights come on immediately. I can accept if this is a one off quirky thing but don't want to be stranded at any time with no lights if this doesn't sound right.

I can check what mine does later this week (need to code from 'scandinavian' DRL = always dipped beam back to normal DRL for that)
Guess you have xenons with LED DRL?

'Early' is not referring to coming home lights - its an adjustment of the sensitivity of the light meter which will bring the Auto lights on sooner (ie with more light) than the default 'normal' setting.

 :smiley: yes i realised my mistake there when I checked my settings again this morning. My sensitivity is set to Medium and leaving home set to 15s to stay on but the lights didn't come on to start with but was fine this morning and when checking again last night. Will see if it occurs again...

I do notice sometimes a high pitched buzzing noise from the front lights when they first come on, assume this is normal and they are not going to pop

Sorry just realised I was posting in the mk7 section so might be different in the mk7 compared to the mk6.

Only inasmuch as the mk.7 has xenon lights as standard in GTI and GTD trim (so no adjustment wheel for headlight range).
