Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to be showing you how to replace the fog lights on this 2007 Audi A4. Often the fog or driving lights get wiped out by rocks as well as get dulled by sand and stuff from the road. For this, you'll need new fog lights from 1AAuto.com, a jack and jack stands are kind of optional, you may want to lift it up, it makes it a little bit easier. Made it easier for us to film it, for sure. Flat and Phillips head screwdrivers, T20, 25, and 30 Torx sockets, 10mm socket, a ratchet with extensions and a flex joint, and a flashlight will help.

If you want to replace your entire assemblies, you'll need to remove the bumper cover, and you may want to jack the vehicle up on each side. You want to jack under pinch weld right where that red circle is. Put your jack and jack stands there. The green circle is just a little triangle that notes from the outside of the body where that lift area is. There are three fasteners. You can see that I'm going to point to one here, and then, there's one on each side. They're just flat blade, turn them about a turn out and pull them down.

Then, you want to remove the T25, and you may find some Phillips screws in there as well, but you want to remove the screws on each side so that you can pull the inner fenders back. You can turn your wheels to be able to get to those screws. You can see here, I just pull my inner fender back out of the way, and then that's going to expose inside. There are two 10mm nuts that you need to remove right there and repeat this on both sides. Then, you can use a couple of extensions, a flex joint, and 10mm socket to reach up in there with your ratchet and remove those. Then, there are three T30 screws as well as two T30 fasteners right down in there that you need to loosen.

Once you have all those fasteners out and loosened up, pull the sides out and then the bumper cover comes off. If you wanted to see a more detailed illustration of this that's a little bit slower, you can check our other videos out for the Audi A4 bumper cover removal. Then, it comes off and you need to disconnect your fog light harness.

With the bumper cover removed, it's easy to access the back of your fog lights. You'll want to disconnect the harness, and there's a tab that you need to push on it and because of dirt and sand, it can make these difficult. What you want to try and do is push up on the harness like you're trying to connect it, then press the tab. You'll hear it click and then disconnect the harness. Then there are three T20 screws, and I'll just fast-forward as I remove those three screws, and you can remove the fog light.

Bad camera angle here, but the new fog light from 1A Auto is exactly the same as the old one, it's going to bolt in there just like the old one. If you need to change a bulb out, the bulb just turns counterclockwise, comes out, new one goes in, clockwise to lock. Make sure there's no debris in that area, and your new one will replace your old or broken one. Correctly goes right in.

Make sure that the harness is out of the way and then I always thread in the bolts first, make sure each one's started, and then you can tighten them up afterwards. Obviously I'm doing the passenger side, the driver side's the same procedure, and once you have them tightened up nice and firm, reconnect your harness and you're ready to put your bumper cover back together.

Then, put the bumper plate cover back on. Remember to re-plug the harness if you have fog lights and then lift the cover up into place.

You want to make sure that those two bolts that you loosened, make sure that the forks that are in the bumper cover go around those retainers and go in correctly. I'll show you here in a second. It kind of can be a little difficult to line up the cover between the headlight and the mounting points inside. I'll kind of give it a little force and it doesn't quite go. What you need to do is push this or pull the headlight to the side so you can line up down inside. It's a little difficult to see, but you'll see ... I'll mess with it a little bit.

It's one of those things that once you get it, it goes in very easily. What I end up doing is pulling the headlight to the side so that the bumper cover can go in correctly and easily. As you can see, once you get it right it goes right in nice and easy. Do it for one side, and since I figure it out, it's really easy on the other side. It goes right in. Then, latch the sides into place.

Then, I'll speed up here as I put those three bolts in at the top as well as tighten up the two T30 retainers that are down inside the holes. Then, I'll continue to fast-forward, put in the two nuts that hold the cover to the fronts of the fenders and tighten those up. Then, we'll put in all the T25 and Phillips screws that hold the inner fenders in, and the only part I don't show is... You obviously want to put the three flat blade screwdriver retainers back in at the bottom and you should be all set.
