Thanks for this, very helpful. Mine appears to be incorrect after the car was lowered. Do you mind sharing the method you used to get yours to the correct level?
Mine was fine, then I had an MOT where they said it was out and adjusted it via the screws for free (it having passed the previous 2 MOTs just fine...), and after they'd done that it seemed really low.
I just parked up facing my garage door, then tweaked it up a bit. I'd measured the height of the bulb from the ground, and measured the height of the cutoff line in the light pattern on the door from the ground, so I knew roughly what I was aiming for (you want it slightly below horizontal otherwise you'll be dazzling people the whole time). Mine weren't even quite the same as each other after garage interference, so I got them the same. (This is all just turning the height plastic allen key bolts, and watching the beam move slightly as I did it). I erred on the side of caution, then slowly tweaked it up a bit more a few times after journeys where I felt it was still too low and I knew it wasn't dazzling anyone. I can't remember which way you turn for up - perhaps anticlockwise? - but just turn a bit whilst watching the beam.
But....
If you've had yours lowered, then that's actually potentially more of a candidate for doing the VCDS recalibration of the sensors. I think that's where you effectively tell the levelling system the new "normal", as yours probably thinks you've got something heavy in the front and the back right now, so is trying to compensate. I've never done that, so don't know the procedure off-hand. I'd guess that the idea is that you reset the sensors first (so it learns the new "normal"), then do the mechanical adjustment to get the lights pointing the right way whilst the car thinks it's all normal.
If you adjust yours using the screw only not VCDS, they'll stay where you put them - it won't notice or try to cancel out your adjustment - but if your system currently thinks there's something heavy in your boot so has lowered the lights, and you adjust them to point higher to cancel it out, then when you actually put something heavy in the boot it might not have enough automatic adjustment left to cancel it out.
So yeah - you might well be OK just tweaking it up like I did, but unlike mine your sensors are probably out of calibration now as your normal ride height has changed.
