Hi all,

I'm looking to pre-emptively replace the xenon bulbs in my A4 B8 2012 (facelifted model) in the next month. Given that xenon bulbs are a little more dangerous than halogen I was planning to disconnect the battery before swapping them over.

Thing is, I have no idea what happens when I do? Am I going to run into issues with radio coding or any other systems?

If anyone knows I'd greatly appreciate it.

Thanks!

Chris
