Hey there! Glad you found it useful :-) Yes, if you have the 17mm hex then absolutely get it in there! It's a pretty big hex however, and not many 'standard' tool kits will have one of those, but agree 100% it's better than the screwdriver if you do have one!! :-) --- To help support us (for both you and others reading this) there are a few things you can do: 1) Please ensure you subscribe to our KZfaq channel. 2) Please give our video's the Thumbs Up on KZfaq. 3) Please help spread the word, the more people who know about us the better!

Thanks for the dimensions. I was doubtful if it's 19mm or 17mm.

Thank youy - much appreciated! Yes, it can be quite common. Usually you will see this by condensation in the lens, often most visible in the reverse lens as it's clear. You should check the rear seal around the bulb plate first to make sure that is seated correctly. Assuming it is, then check for condensation, and if needs be remove the light and have a good look inside from the rear and tip it back and check for any water. Best of luck!

Hey there! Thank you very much - glad you're enjoying our videos! From memory, I believe that the headlight must be removed to change the main bulb. I may be wrong on that, but pretty sure for the B7 model. Do you mean the subwoofer screws are rattling? If you remove the speaker grille cover within the parcel shelf then you will be able to access the screws and tighten them up. We do not have plans for these two video's just yet, but we have a LOT of content coming!!! Be sure to support us - subscribe to our channel and spread the word!

..so..how can i remove the speaker grille cover within the parcel shelf? :) can i simply..pul it out?

Yes, it just pops off. From memory the front edge pops up and rear edge has hooks, so comes up then forward. That is from memory though...

Because it's LED :-) LED bulbs can cause various issues on cars not originally designed for them. You can get CANBUS-friendly bulbs which should stop them throwing a bulb out warning. But the LED bulbs can behave differently, including twinkling when first switched on, pulsing as you have seen, etc. Will be the bulb, and you can have a bulb from one company that acts odd, and then another made by someone else which works fine. --- To help support us (for both you and others reading this) there are a few things you can do: 1) Donations both needed and welcome!

When you say Limousine do you mean the saloon/sedan, or an actual Limo?

Total Technik I have an Audi A4 B7 Limo and I am very interested to know how to remove the complete original tail lights (also fron the trunk) to use LED taillights. But I don’t know how to remove the originals. This would be great if you can make a video. ^^ (Limousine is the german word for Limo: thought this would be the same than in english)

When you say Limousine do you mean the saloon/sedan, or an actual Limo? This video is for the B7 saloon/sedan. On many original build labels they refer to the saloon model as a Limousine, which is what I assume you have? Rather than a stretched Limousine?

I mean the normal A4 B7 (not the Avant). Yep, the sedan. How can I remove the taillights?

Ok, you can watch this avant video first as the process is very similar, but then also watch the B6 saloon (sedan) removal video as well, which is here: kzfaq.info/get/bejne/hdCojLJq05uqooU.html Between those two video's you will have all the info you need to easily remove the B7 saloon/sedan rear light :-) We hope that's useful for you.
