Headlights

Ive been wondering that as most of the places I look the part number comes up with one dial. I wonder if anyone can tell from the picture if the leveling motor is there or not? My car sure has the symptoms that @tiggerfish describes. Maybe its just coded wrong.

Oh good points! This is interesting!

You don't have the leveling motor...

And here's a US manual - it doesn't include the levelling wheel - just the dash brightness one. Please accept my apologies - I had no idea this was a thing!

I changed my projectors the other day - you can see the levelling motor here...

Unless it's the angle of your photo, I don't see that part in your headlight.

I wonder if yours is coded incorrectly, or if it's something else now. I think the best next step anyway is to get the BMW software, as it'll be guesswork otherwise.

Now Im wondering if there is a software update that may have been incorrectly added the leveling headlights. Or is it just a code. Unfortunately I only have had a work laptop for many years. I havent really needed a personal one. My old laptop is XP and isint running that well. It isint even good enough to update to a newer OS. Once I sort that out Ill learn to code. Thank You everyone for all the input so far.
 
You're probably in luck tbh - this stuff was all made in the Windows XP era, and trying to install it on anything later than Windows 7 is actually a total pain! (Driver compatibility/signing and other stuff like that)

Thread 'Diagnostic tool. BMW scanner 1.4. Review'

IN THE BOX:
Diagnostic tool
Connection cable between OBD and USB port (for laptop)
Mini CD with software

The hardware/scanner arrived in a small pouch which was very basic. The Mini CD contains all the software needed, although it really is better to download it from the web.
Upon inspection, a common theme as comments in Amazon (where I got the software) is confirmed: the unit looks flimsy and it is not very robust. I tried it on an X3 (e83) and, as the OBD port is next to the driver's door, had I closed the door completely the unit would have suffered. A bit of...

That'll do all you need it too, and even usually comes with a CD, so no need to connect Windows XP to the internet.
 
Back to my original question. Which are the highbeams and which are the low beams? I'm assuming the outside projectors are the Low beams and the inside are the high beams? All 4 of mine are on so I have no idea.

It's hard to answer exactly what lights come on when, as you can change it with coding to an extent, but a standard factory UK/EU model car:
- off: no lights
- side lights: rear lights, interior lights, small sidelight bulb at the front
- main beam: as side lights + halogen projectors (outer)
- full beam: as main bean + halogen non-projector (inner) + blue light on the dash board
Click to expand...
Projectors = main/low
Other lights = full

The main and low beams won't change between projector/not projector with coding. (But you can make the full beam be on at 50% brightness on its own as a DRL, but that would extinguish the projector if that were the case, so it is possible you'd have the full beam on on its own, all the time.)
