GR86 Headlight aim too low

Did you do all of them or just the dipped beam? I feel like main beam probably doesn't need any adjustment.
Ah not sure about main beam didn’t know there was an adjustment for that, I was on the understanding this adjusted with the dipped beam but could be wrong, so for me I just adjusted the dipped beam.
 
Also the manual said you need a Philips head screwdriver but they are actually bolts (perhaps 8mm?). No bit deal though as space is so tight you wouldn't get a screwdriver in there, so a small spanner is probably your best bet.
Welp...maybe you can ignore this. Someone in the US worked out that using a screwdriver might actually make it easier :D

 
I adjusted mine today to lift them a bit, following the US thread where they reference you need to adjust both 'wheels' (2 per side) to the same amount of turns. I've no idea what the second one does as I've matched it but the dipped beam didn't move at all. You need a long thin shaft 👀 philips to get to the back one.

So yeah, only the 'accessible' wheels seemed to do anything to the level, but who knows. Maybe it's a high beam thing but i thought that just lifts it a set amount from low beam.

Hopefully I can improve the naff all visibility on dipped beam as we head into the darker months

Reading that US thread, it's not totally clear but someone speculates that the wheels aren't actually adjusting the lens, they are adjusting the entire headlight housing, with one for each side. Hence needing to adjust them both in tandem. I still haven't done it myself, mainly because I don't have a long enough screwdriver :D, and I've kind of forgotten about the issue during the summer. But now the evenings are getting darker, it might become a priority again.

Yeah, I think it'll help. I raised up about an inch, maybe a little much but we'll see.
I'm a bit perplexed at the double wheel thing, but had a few days apart adjusting as I didn't have the longer screwdriver either, can't imagine any harm done, just remembered how many turns on each side and roughly matched it.

Now to adjust that melodramatic light sensor, most bridges seem to set it off even in broad daylight. I'm sure I saw the setting on techstream to adjust sensitivity so I'll have a peruse.
 
Yeah the setting can be adjusted in Techstream.
I realised the other day that my headlights have actually been switched permanently on for the last few weeks, and I've just left it. Weathers getting grim, so auto won't always put them on when they should be on, and when you shut off the ignition they go off anyway instead of just bleeping at you.

Do you not have welcome lights when you open the car? If you leave them on they always come on when you unlock the car. Mine do anyway.

Yeah but they would do that if the lights were left on auto and it was dark anyway (if by welcome lights you mean the headlights coming on?)

They're not much better on minimum sensitivity, I still often end up switching them on or off manually.

The calibration of the light sensor is terrible, even on least sensitive setting it is not great. They can't have spent more than 10minutes on it during development!

Out of interest, how many turns did you give it, and did it make much difference? Just wondering how much adjustment is allowed.

I measured about 45 'quarter turns of the screwdriver' average each side. In fact I used my garage door with some tape to try get them the same lift, right side was more like 50 and the left about 40, but I guessed that it didn't engage properly sometimes. I ended up backing them both off by about 15 as I was getting flashed 😕. Tbh even in the day I could see it was lighting up signs which felt a little high so no surprise.

Really I should have done the proper calibration close + far test (certain amount of m from the car) but I'm going with what I got for now and will fine tune.
 
Thanks. I don't have easy access to a wall or garage door that I can point at to measure them. Was thinking of just giving each knob half a turn and seeing how it goes.

Looks like I was wrong about this. Went out to the car tonight and unlocked it and the headlights didn't come on. Headlight switch was in the "On" position. Switched them back to "Auto", locked the car, unlocked again....lights came on. So welcome lights do only work while the switch is in Auto.
 
Would anybody be able to take a photo of the beam pattern against a wall from a distance? It would be quite helpful to have a standard adjustment for reference.

This any good?

Front edge of the car is 105cm from the garage door and the height of the light measure in the red circle is 73cm

That's great, thank you! I don't suppose you'd mind doing one at something like 5/10m too if you can?

Find a multi-storey car park, a concrete wall, and some illumination.
