I have a Confort Control Module here, in very good working condition. Its the one that controls the interior lights, remote door locks, alarm system, memory seats, etc... located under the driver's seat, which sometimes gets wet and corroded. This one is Clean.. Fits all B6 A4 and S4 $200 shipped

I know my '02 A4 has some electro-goblins (seems like fob fail when doors won't open or alarm goes off randomly when pressing buttons and needs reset). Sunroof will shut (tilt down to close with no raindrops or other provocation.
Is there a way to determine whether the fob or Comfort Control box is source of problems?
You will need VAG COM to pair the key on a B6. Also, the only way to know for sure if it is the central convenience unit is to scan the car and see if it comes up faulty.
That being said, the issues you list sound exactly like the problems I was having before replacing mine. I used my VAG COM to reprogram fobs (very easy to do) and everything works great now. I wound up buying a new unit for $300, didn't want to spend 150 on an eBay one not knowing if it would last 10 days or 10 years. Also, these units fail without having ever gotten wet. My car has never seen water inside or had wet carpet (I purchased it new) and my central convenience crapped out.
