I've just replaced mine so here goes. Undo the top two bolts first. Then remove the two screws above the radiator holding the air intake ducting in place and gently pull out the air intake pipe and move to the back of the engine, exposing the rear of the lightbulb housing. To the rear of the lightbulb housing is a bolt. You should only need to loosen the bolt and this will allow the lightbulb unit to be pulled forward clear of the car. On the back of the housing you will find a cover, remove the clip retaining the cover and fold it away, exposing the rear of the light bulb.
Enter through the wheel arch mud flap. Put your steering on hard left hand turn. Pull out the wheel arch section ( flexible and easy to manipulate.) The box is there in front of you to unclip and pop in a new bulb. Audi A4 2003 on

to change the turn signal bulb on the headlight there is usually either a screw or tab that releases parking light lense from headlight. to just completely remove the headlight there are the two screws up top and also two lower if we are taking about the right side(drivers side, standing in front of vehicle) one of the screw is to the right side down near the inner fender, it is even with the bottom of the headlight. the other screw can be seen between the headlight and the radiator support about in the same area just opposite the other side. take a flashlight with you, not too hard to see
The easiest way is to remove the headlamp assy. To do this removed air duct on RH side. remove 2 philips screws and pull up on other end at air filter box. Next you will see 2 Torx T30 bolts that are holding to headlamp mouting brackets. remove these completely. Get a flashlight and look down inside eng bay you will see 2 more mouting points w/ t30 bolts. loosen but dont entirely remove these. Slide headlight out. The park light socket has a big fin style tab grab firmly and twist counter clockwise. Be sure after removing the bulb that the socket contacts aren't burnt up. If they are you need a new socket and bulb. Before reassembling test lights to make sure they work properly and install in reverse order of removal.
For the RH headlight, First remove the top cover of the ECU module just behind the headlight. Then remove the middle section leaving the ECU in place. Both parts are just clipped in so should come out fairly easily. You will then be able to get access the the headlight bulb, release the spring clip at the top (using a mirror helps) and the bulb should come out. For the LH side remove the air filter housing.
1] remove th headlight assy. by removing the bolt on top of the assy and the 2 rod retainers.
2 ] remove the electrical connector from the headlamp bulb cover
3] rotate the bulb cover counterclockwise and remove cover
4] disconect the bulb connector
5] rotate bulb retainer counterclockwise and remove th ring
6] remove the bulb using a slight rocking motion
7] reverse proceedure to install
There's one more "hidden" bolt. Above and behind the corner of the headlamp, along the top ridge of the fender, there's a hole in the fender lip. Shine a flashlight down in there and you'll see the head of the third bolt. Remove that, and the headlight assembly will slide forward so you can change the bulb.
Take out the two Torx bolts on top of the headlight assembly. Then there is a third hidden bolt. Look through the holes in the top front of the fender, above and behind the headlight's turn signal portion (you'll probably need to shine a light in there) and you'll see the third bolt. Remove that and the headlight pulls straight forward and out. Then you can change the bulb.
hi there the solution is simple, you only need to undo the screw on top of the side light/indicator. then facing the head light place a flat headed screw driver under the bottom lip of side light. the bottom of the lihgt is on a small push fit stud, use a sponge or cloth to protect your bumper paint work then just apply pressure gently to lever side light out towards you, It will come dont worry, you may then change your bulbs if you wish remove the whole light unit you will see the bottom bolt as soon as you release the side light. to replace just push back into place then replace screw. whole job takes about five minutes
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.
