I installed the headlights, and to my surprise, the wiring for the autolevelers are there.

I have no idea if it's just wiring, or I actually have the sensors.

I'm going to hook it up to a vag and see if I can enable it.

Pins 5 Gnd, 6 Neg and 7 Pos at the headlight connectors should be for driving the leveling motors. Mine is present but I have not checked to see how far back in the wiring system they go.

If you can't see Auto Levelling Controller Address 55 in VAG then I doubt controller is present under right rear seat. My Address 55 does not respond.



Know that sometimes Audi does not continue wiring harness end to end for systems that the car did not ship with and vice versa. For example when installing Euro OEM Valeo B5 S4/RS4 xenon headlight assemblies in CDN 01.5 S4, I recycled the found in place OEM front bumper fog light 2 wire harnesses to power the additional Euro City Lights option inside new assemblies hoping to use all OEM Canadian Spec front end wiring. I passed fog power thru CDN headlight connector unused pin 3. After modding the Fog Light Control Module to always turn on Bumper Fogs aka now City Lights... they did not power up!?! Turns out the front bumper fog light harnesses stopped at both A-Pillar wiring blocks and did not continue in next half of CDN in-dash harness as per US / Euro spec where both sides meet the Fog Light Control Module behind glove box. After spending way too much time keeping front headlight connectors looking stock with no under hood hack wiring jumpers... it was more fun opening both A-Pillar harnesses to borrow City Light power from Park Light wiring block. Bentley wiring diagrams are accurate.

My yellow jumper wire installed (center) in both side A-Pillar wire blocks to enable front Fog aka City Lights via front fog wire harness.



We may in for something similar for the headlight leveling wiring.

Have you checked front and back pass side suspension for the leveling sensor harnesses?

IMO that will be the most difficult to install in OEM harness paths.

yeah, i suppose it's just the wiring then. I soldered them for nothing.. haha

I haven't gotten a chance to check for the leveling sensors, way too cold to do so.

I think it's safe to say that the feature doesn't exists for canadian s4's.

Thanks for the replies everyone!

ps. Anyone know which VAG COM code I need to change my headlights from "Halogen" to "Xenon"? I have spent some time looking for them online, but have come up empty handed.

There is no VAG code to change. You have to bypass CDN halogen headlight DRL feature with a wire jumper in driver knee bolster relay block, install xenon ballasts and xenon bulbs ideally in "made for xenon" headlight assemblies to get proper xenon cutoff.

kbjy11

Hmm..

Is there anyway you could go into detail???

Are you sure you can't disable the DRL from the VAG COM?! i am quite certain you can...

but right now, my headlights do work... but they are on 100% of the time when the engine is on. Another issue is my gauge needles never light up which i think is somehow related to my headlights...

When i bought the car, there were ebay sonar headlights installed on the car and they did sort of a hack job..

With later years you can but not with B5's as DRL is controlled by a relay. Let us know if you find another way with VAG.

Here is the stock relay block, CDN DRL relay is #209



Remove 209 and install a good quality jumper as doc'd on AW. This position allows headlights controlled by headlight switch (not auto on with ign on). Sounds like someone installed a jumper to use your xenons as DRLs which is OK if you don't have Euro City Lights as DRLs. You should be able to see jumper with driver side dash Fuse Cover removed.



Projectors are different for halogen and xenon headlight assemblies so mismatching bulbs will output light but not with beam patterns as designed for each.

Sell me your levelling motors so I can get them working in my car

kbjy11

ahhhh.. dude you're the man! thanks alot!

I have plans for the motors!

Manual headlight level control project <pics> DONE! - Page 3 - Audizine Forums

K04-S4

Manual!?! Where's your sense of adventure.. go OE Auto

kbjy11

ok so I finally got a chance to take a look at the 209 relay.

The 209 relay is installed.

I will install a jumper like the pics indicate. Do you know where I can buy one locally in Canada?


Hmmm.. do you know where would this jumper be located? Checked for jumper in the fuse area.. can't find it..

Are you running true Xenon Headlights with actual Xenon Ballasts or aftermarket Halogen Headlights with "Xenon Color" bulbs?

If your running true Xenons with Ballasts and using stock CDN halogen headlight wiring, you need to pull Relay #209 and jumper it asap as the xenon ballasts are at risk of being damaged. For OEM CDN Halogen headlights, the #209 CDN DRL Relay supplies low power with ign on and high power with headlight switch on. If you follow my earlier jumper pic, the fallout issue you will have is no DRL headlights with ign on. I wouldn't do this as it breaks CDN DRL laws and increases accident risk. One option you may want to consider is reposition jumper to always power up true xenon headlights with ign on to maintain CDN DRL standards.

If your running true halogen headlights with "xenon color" bulbs then you don't need to pull #209 or change anything else to maintain CDN DRL spec and OEM halogen headlight operation.

With the fuse panel cover removed, look past the fuses to see the Relay Block further inside dash as it's directly above driver side footwell area. Otherwise remove driver knee bolster to fully access Relay Block for removing #209 and installing a jumper. If you need one, make a good quality jumper as your headlights operation will always depend on it.
