Effduration is on a distinguished road
I have two facelift E53's and therefore four A-pillars...I have encountered a leak, or kinks (resulting in a drain blockage) at all four of them...

I never use the pano sunroofs..

Because the A-pillar leak is so common, I would pull the A-pillar before I pulled the dead-pedal trim.

I can't explain why exactly, but the rubber drain hose has just enough slack to move around and often pulls itself out of the metal drain tube...I don't know if this only happens in freezing weather or not. The solution is to zip tie it so that it has less slack.

I do not disconnect battery when pulling the A-pillars. Yes the airbag is there but don't go near its connector.
