How to Disable Range Control?

[Betq]

I recently purchased b8.5 ecode headlights and when plugging everything in, I'm receiving faults saying auto-level circuit is open.
The dash says the auto level is defective.

I manually adjusted the lights and I don't care much about range control...

Does anyone know how I can disable it by long code or any other method? These lights look amazing but the constant reminder that it's defective is getting on my nerves.

Did you try clearing codes first? I just had a "Headlight range control defective" code stick when I ran the car with the lights unplugged, that fixed it for me.

Yea... unfortunately it popped right back up after :/

Strange.. I had to clear codes twice for mine to go away maybe try clearing them again? Or try unplugging them and plug them back in?

Are they Audi headlamps or third party generics? Because the wiring at the headlamp plug to the V48 motor is the same for US vs. EU and for B8.0 vs B8.5 in that regard. Pins 1, 2, 3, and 4 on the 14-pin plug. Assuming you got the correct ones for PR 8Q3 (HID) vs PR 8Q5 (HID w/ AFS).

Have you tried running the Basic Setting for headlight adjustment to see if it can re-learn the home position and upper/lower limits? VCDS instructions are here.

Didn't know about this one. My projectors used to point down then up to their normal position every time I started the car but ever since I swapped in some upgraded projectors(non AFS) they no longer do the down/up movement. I've got a VCDS rental for the next 7 days, could this potentially fix that?

Well, the problem is your fault code is about open circuit, not about no or incorrect basic setting (at least based on your opening post).
Performing the basic setting for the headlamps is "prepare car (on level surface, fuel tank full or almost full, driver or equivalent weight in the driver's seat), start process, manually aim headlamps to correct orientation (1% down angle from level), then complete process". This tells the range control module "this is level", reading the level sensors on the suspension during the process. The movement of the lamps at car start is just the diagnostic performed at each startup.

Perform a full vehicle autoscan and post the log here so the actual DTC(s) can be seen.

Headlights should be OE, came in a Magneti Marelli box and has the Automotive Lighting sticker on both headlights, here's the listing that I purchased them from https://www.ebay.com/itm/Headlight-R...72.m2749.l2649.
I try the basic setting adjustment and scan/post the logs once the car gets back from the shop unless they fix the issue while it's there

Also didn't notice this 2nd bulb exposed in the headlight until they were installed, does anyone happen to know what their function is?

Looks like a cornering light to me... maybe works with AFS?

Did you get AFS lights for a non AFS car?

This is correct. That bulb is for your cornering light and will come on when you turn the wheels based on a module that reads speed and turn input angle.

Does OP have AFS?

[Betq]

It's a B8.5 premium plus no AFS, headlight listing says it was for vehicles with automatic headlight leveling and no mention of AFS. It did mention it has "with bend light", so it could be for non AFS optioned with cornering lights?

[bakedziti]

No.

[Smac770]

Cornering light, bending light, these are terms synonymous with AFS. So you have a PR 8Q5 headlamp on a PR 8Q3 car, which means the leveling and swivel motor pins are not matching.

PR 8Q3 uses pins 1-4 for the V48/V49 tilt motors. These wires come from the J431 control module in B8.0 or from the J519 in the B8.5.

PR 8Q5 uses pins 1-2 for control, pin 4 for power from a fuse (panel C, column 1, fuse 7 and fuse 6), and pin 14 for ground for the J667/J668 modules on the headlamps that control the V48/V49 tilt motors and the V318/V319 swivel motors. And the 1-2 control lines come from either a J745 control module in a B8.0 or the J519 in a B8.5. In a B8.5, maybe a little wiring and some recoding and you could enable AFS to make use of the headlamps without error. But you need a different headlamp range control module and additional wiring to do AFS in a B8.0.

As for range control, the point is for the benefit of the people you're blinding, not for your benefit.

As stated above, you bought the wrong lights for your car, see if you can trade those back to them. Otherwise you will likely need to code out the auto-levelling stuff at all and make sure you aim them properly.
