2006 A6 Quattro tail light logic boards - left/right swappable?

[Eliot Sennett]

My driver side tail light is acting up - the brake, turn signal and reverse lights work sometimes and don’t work sometimes, with no pattern I can figure out. I’m guessing the logic board is going bad, since it’s affecting all three sets of lights.

I have a spare tail light assembly for the passenger side. Can I swap the logic board from that one or is it set up to only work on the passenger side? Thanks.
