EDIT: Just did some reading on the web. Seems that Audis just don't like LED bulbs for exterior lights. For interiors and license plate lights, they're fine, but for any other exterior bulbs, they always throw codes. Oh well, live and learn. Off to AutoZone.

I live in Sweden and have thought about changing mine, but maybe the weather here is too cold, I don't want to have errors every morning...

On another note, I broke a clip and a tab from each of the plastic covers that hide the torx screws. Is there a secret for putting these back in? They just don't want to go back in the same way they came out lol

Do you think they are connected or coincidence?
