A4 B-pillar noise

[Ed Slaughter <edslau@teleport.com>]

My A4 has a rarely heard rattle in the passenger B-pillar when driven 
over bumps, especially if it's cold.  I remembered vaguely reading on the 
list that this problem was known and has a documented fix.  I have an 
appointment with the dealer to fix the problem, but when I told the service 
guy I thought there was an Audi bulletin on it, he acted confused.  Can 
anyone tell me whether I'm hallucinating, and if not, how to point the 
dealer at relevant Audi instructions?  I have little faith in random 
searches for intermittent noises.  TIA.
