Do it yourself, replace the glass of the side mirror on Audi A4 B8, the model made between the years 2007 and 2015. Normally, you don’t need tools to make this replacement, but in some cases, we recommend you to use hand gloves or a flat blade screwdriver. You should be able to do this simple replacement in less than 5 minutes.
In the beginning, you must remove and get rid of the old glass. In most of the cases, the glass is broken and you will have to pry it out carefully from the mirror support. You can do it by hand, as you can see in the image below, but for your protection, we strongly recommend you to use protective hand gloves or a screwdriver to remove it. The screwdriver is also recommended if the glass is intact and you wish to take it out without damaging it. But be aware that it can brake very easily, if you apply too much force on it.
After you detach the glass, you will see two thin wires connected behind it, as those marked with red arrows in the next image. They heat and defrost the mirror and you must unplug them, in order to remove the glass completely.
Connect the wires to the replacement glass and insert it into the mirror support, making sure its plastic brackets are aligned correctly onto the sockets on the support. Press on it to secure it there and that should be it. For more details, you can watch the video tutorial below. This is all you need to do, if you wish to remove and replace the glass of the side mirror on Audi A4 B8, made between the years 2007 and 2015.
