Audi A4 LED Interior Lights How to Install – multiple generations 2009 – Present

Let’s take a look at how we’re going to remove the front overhead dome covers
to get access to the old halogen bulbs. You’ll be using the fork shape tool. And you’ll be inserting between the
plastic trim and the plastic housing here. Now when you insert between, you’re
going to pry it lose to separate the plastic lens cover from the overhead dome. You should be able to release the cover. When you flip it around, you should be
able to see about 6 to 8 plastic clips that are holding that cover in place. You’re gonna use the pointed wedge tool now
to remove the old halogen bulbs in order to replace them with the new LEDs. Now in order to get access to the two
front overhead map lights, you’ll need to remove the entire overhead assembly to get access from behind. You will need a T25 style torx …
torx wrench and you’ll need to remove the screw
from the sunglass holder. Once you have that removed,
use the blunt edge of the pointed wedge tool to gently pry and release the entire assembly. Once you have the assembly removed, from the back side you’ll see
two twist to lock T10 connectors. You’ll be turning them counterclockwise to release them,
and just pull them out. Once you have them released, you’ll be able to remove the T10 bulb as shown here just by pulling them out with your hands. You can then replace it with the new LED. When you insert them again,
turn them clockwise to secure it in place. Go ahead and test those LEDs to make sure they work. If they don’t, you can always of course reverse the polarity of those LED bulbs
and then reinsert them to test again. To insert the overhead console back into the headliner, just push it back in place. Screw the T25 torx screw back into place and make sure to replace the cover for the overhead dome lights from earlier in the installation. Now, it’s a little bit easier to get access to the
rear overhead dome lights because there’s only one assembly. Again you’re gonna to use the blunt edge of the pointed wedge tool and you’ll be using it to gently pry it loose, not from the headliner,
but from the actual assembly that’s in the headliner. Just run the tool around the edges until they pop out. There should be four connectors holding it in place
once you flip that cover over to see. You can use your fingers to remove those T10 bulbs and replace them with the new LEDs. Again, once you have the new LEDs in place,
you’ll wanna go ahead and test. If they don’t work, it’s ok. Go ahead and flip them around
to reverse polarity and try again. Let’s take a look at the courtesy door lights. You’ll be using the pointed wedge tool to remove the assembly from the door trim. Insert the pointed end into the housing
where there’s an indentation and you’ll be able to pry the housing loose. You’ll wanna remove the plug to remove power
before working on this assembly. Once you have the plug removed,
you need to remove the black protective cover in order to gain access to that halogen bulb. You can use the pointed wedge to remove the T10 bulb easily from the housing. Once you have it out, insert the new LED. And plug it back into the connector
just to test to see if it works. Again, if it does not work the first time, reverse the polarity of the LED and try again. Make sure to replace that black cover
before inserting the housing back into the door. The Audi A4 trunk light is essentially
the same type as the courtesy door lights. You need to enter the tool into the indentation the assembly to remove the assembly from the aluminum lining. Follow the same steps you did as the
courtesy door lights, and you’ll be able to install this one pretty quickly. Now in order to gain access to the license plate lights,
you’ll actually be using two tools. The blunt edge of the pointed wedge
and when we consider the rounded wedge. There is a section of that license plate
housing where you can insert the first tool and force it towards the outside. And you’ll use the other tool’s edge
in order to remove it by prying down. Once you have the assembly out, you’ll need to get access to that festoon type bulb to remove the halogen and replace it with the new LED. Now the LEDs that we use for the license
plate light are CANBus type LEDs that are required in order for the lights
not to give warnings on your Audi’s dash. Once you have these ones inserted, go ahead and test before reinserting the entire assembly to make sure they work. As always if you have additional questions or comments, you can reach us on the web at There’s also a contact section available

    The license plate lights are slightly difficult to remove. As we show, the first tool is pressed into the slot next to the lens. With that tool in, we pushed the housing towards the right which gave a gap for us to use the 2nd tool and pry downward.

  2. By using improper tools, I ended up scratching off part of the trunk paint, bent the plastic slot and ripped the rubber seals on the light housing. Time for a touch up pen and some super glue which costs 3X more than just buying the tools on your website. Really should have done that instead. GG

  3. is it just the number plate light that is canbus, will the lights be fine with standard LEDs. Also what size are the festoon bulbs?

  4. Nadim,

    Select bulbs in the interior are CANBus based as well as the license plate lights. If you have specific questions about the products seen in the video please use the contact form on our website so that it can be tracked and answered.

    Thank you,

  5. Lights need to be CANBus to prevent error codes for the License/Number Plate. The Interior LEDs also need to be CANBus in select areas to prevent error codes as well. The package we sell has all the correct CANBus resistors to work error code free!
