  • Adjust headlight cutoff level for full LED lights

    Does anyone know how to adjust the low beam level on a C7.5 7 with full led lights?

    Sorry if this has been covered — I couldn’t find the answer.

    Wow I completely missed that. Looked once and didn’t immediately see them so I figured you had to do it through vag com with these.

    Just looked again and the screws are painfully obvious

    Where are these screws located please?

    Just be careful not to raise them too much. I thought mine were too low so I raised them but little did I know I was blinding the hell out of oncoming traffic and even got pulled over because the cop thought I had my high beams on.

    Once you adjust it just stand 10-20 yards away and you’ll know if they’re too high.

    Here’s a shot of the A7 LED. There’s a screwdriver in the correct screw. It’s white nylon, hex hole with Phillips head slots in the bottom.

    I’m rural and my lights were very low. I raised both sides two full turns to start then fine tuned.

    I am not 100% certain on this, but I believe you need to put the headlights into ‘adjustment mode’ through VCDS prior to adjusting the screws. Otherwise, they will simply level internally through the motors to compensate and cancel the screw adjustment.

    Thanks for the photo tenspeed that makes things easier I appreciate it.
    When I park in my garage and the lights are shining on the wall I can see that my drivers side light is lower than the passanger side, I just want to level them out.

    I’m certain this isn’t the case. I’ve been messing with mine for weeks trying to get them just right as they were too low when I got the car. I adjusted them the first time and way overshot and they were too high, so no auto level there.
    Some advise adjusting these: turning the screw to the right raises the beam. Start with quarter turn increments and see how you like it by driving at night. I was chasing them all over by adjusting too far.

    Edit: here is the Ross-Tech link for the LED headlights. I think your link went to xenon lights. http://wiki.ross-tech.com/wiki/index. gulation_Basic
    Reading this procedure leads me to believe that what I said above is wrong but I definitely did not get a correction back to level when I over adjusted.

    This is by design as it keeps the driver side beam out of the eyes of oncoming traffic in opposite lane. I kept mine that way as I like the idea.

    Although I have not looked at a manual, I am quite sure that properly adjusted LED headlights should have the passenger side higher on your garage wall than the driver’s side.

    European headlights have long had a «cut» in the beam that lifted and extended the beam on the passenger side, thereby making it easier to see obstacles, pedestrians, cyclists, animals, etc. along the shoulder of the road. The old US sealed beam rules prevented us from having that advantage. Euro headlights shined on a garage wall made a pattern that looked much like a hockey stick with the blade sticking up and to the right (LH drive cars). ___/

    I would be shocked it our LEDs did not provide for higher (and therefore, farther) illumination on the passenger side where there is less risk of blinding an oncoming driver.

    Makes sense.. back to the drawing board for my adjustment then. lol. ugh.

    Thanks for the info SlickMachine & Justcured I did not know that.
    I guess I will just leave them the way there are then.

    So I just vag’d and followed the procedure in that link AFTER marking on my garage wall where the lights were hitting. When the lights centered, there was no noticeable difference from where I had them before.. This system of aligning is difficult. I really feel like turning the screws moves the beam and that the lights are not compensating. As a matter of fact, when I adjust the screws I can visibly see the light beam move up or down and the leveling system is definitely not compensating. I also have a hard time believing that a leveling sensor exists inside the headlights themselves, rather I would think that such a device would be attached to the vehicle somewhere more firmly mounted then the headlights. Confused.

    I have questioned the necessity to either the learning mode in VCDS as well. I raised the beam on my S5 and a friends SQ5 a significant amount (after the vehicles were lowered) and have noticed no change in where I’ve set them or other I’ll effects.

    I might try using the learning mode when adjusting the lights on the S7 I initially brought this up for. I have a vag com cable, so it’s not much additional effort

    Right after taking delivery of my RS7 last week, my wife and I took it on a 2,000 mile round trip road trip from Colorado to California and back to visit our family.

    One thing I noticed right away was that the driver side had a rather sharp cutoff that took a fair chunk of the far left hand or median side illumination pattern out, pretty much from 50-60 feet out while the passenger side going much farther. I find it pretty significant and a bit unnerving as wildlife can sprint out from either side.

    I have not done the wall / garage door test yet but appreciate reading that this might be a «feature». I have to have TPMS sensors put in my Winter wheel set at the dealer later so I will have them make sure it is within spec.
