How to replace light bulb on audi a3

SOURCE: 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.

I had the exact same problem. The check engine light would come on then go off. I didn't notice any drivabiltiy issues. End the end I had to replace the flapper motor, the high pressure fuel pump and the camshaft. They showed me the old parts and sure enough the camshaft lobe was worn down and the cam follower that actuates the fuel pump was in pieces. Needless to say it was very expensive. It's been a problem posted on many Audi sites. I went ahead and had the timing belt changed. Now she's as good as new.
