Dynamic Headlight Dimmer Contol Not Functioning

I have an 2002 Audi A4 with automatic headlight dimming. I removed the entire headlight assembly to replace the bulb. When I put the unit back, I now get an error on the status display on the dash that represents "Dynamic Headlight Dimmer Control not Functioning" in the owners manual. There is only one connector on the assembly and it is fully plugged in

    Me too, except I replaced the ballast. the lights are working but not the dimmer control.... the headlights aren't automatically adjusting like they were. Is there another unit that controls that?

    I just purchased a 2002 Audi A4 and I have nearly the same problem. I'm taking it to be serviced at the local VW dealer. Neither of my projectors are working, only the high beams. Inadvertantly, I think this must have an affect on my tail lights because the innermost two bulbs arent functioning either.

SOURCE: one headlight bright, the other dim

For some reason, Toyota chooses to wire their headlamps differently than domestic cars, with dual fuses for the headlamps, and a common ground for each headlamp...The reason that the lamp was dim is the bulb was getting power thru a "backfeed" condition, due to the poor ground. The fuse may have blown due to the poor ground, also.

SOURCE: AUDI A4 2003 1.9TDI HOW TO ADJUST THE HEADLIGHT

There are two adjustment points (screws). For example left headlight: you will see one point near the end of left wing, at bottom side through a wing hole. This is for vertical plane headlight beam adjustment (up-down). Another one point is against water radiator side. This is for horizontal plane headlight beam adjustment (left-right).

At least on the driver side, there really is no reason to remove the entire headlight assembly. I was able to swap out the bulb fairly easily but simply removing the dust cap, popping the connector off the bulb, and then undo the clip holding the bulb in place. The just reverse order to install the new bulb. Took about 3 minutes.

SOURCE: I have a 2000 Audi A4 needs a headlight and now

sounds like a fuse is blown, not sure weather or not the fuse for the lights are inside the car or under the hood. start there and if you dont find anything check the wiring. after that replace the bulbs.

you have to loosen the whole headlight assembly to open the covers behind the lights to actually get to the bulbs. 4 screws, 2 are on the top of the assembly(phillips screws) the other two are hex and attach the bottom of the assembly to the car. somewhat difficult to see but look behind the assembly and down into the compartment and loosen the screws(they don't fully come out) just enough to pull the assembly out. open the black cover behind he low bean and there is the bulb

SOURCE: Can I or how do

Unfortunetly you cant get into the lens to clean it from the inside. The "fog" up that you have is moisture that gets inside. Usually you will have to replace the headlight itself. If thats the case, you can get them used or from a salvage yard if you dont want to spend dealer price.

Audi A4 "left dipped headlight" problem


I have the same issue on my 2002 A4. According to my Audi dealer mechanic, there is a sensor on the front suspension that controls the angle of the headlight. Replacing this may resolve the issue.

2000 Audi a4 headlight bulb replacement


The easiest way to do it is to pull the headlight out of the car. This isn't hard, but you'll have to have a T30 Torx bit to do it. There are three bolts that secure the headlight. Two are on top of the headlight - you'll see them right up there on top when you open the hood.

The third is harder to find. Look where the outer upper corner of the headlight meets the top of the fender, above the corner indicator. There is a lip on the fender that runs all the way back to the base of the windshield, where the edge of the hood sits when it's closed. There is a round hole in that lip near the headlight (just behind it). Shine a light down in there and you'll see the third Torx bolt. Take that out and you can slide the headlight assembly forward. You shouldnt' have to take it fully out of the car, just take the bolts out and move it forward.

Then remove the dust cap on the back of the headlight, pop the connector off the bulb, undo the spring clip holding the bulb, and remove it. Install the new bulb (wipe down the glass portion with your t-shirt to get any skin oils off it, as they'll burn it up quickly), and then reassemble in the reverse order.
