Yr 2000 Audi A4 - Drainage Holes

[d8ean]

seen various posts around the net for clearing out the drainage holes on the audi a4 to help stop leaking inside the cabin etc

Can anyone tell me where to look for them? are they around the boot lid area? doors? this particular car doesnt have a sunroof

TIA

(Might not be any help, but) the A6 drainage holes are right under the battery - mine only blocked up last month. I just aimed a wire coat hangar at the bottom of the pool of water and pushed the rubber grommit out. I believe that's the near-enough-dammit-approved method?

The problomatic ones are under the battery and under the brake servo. THe real problem isnt water in the cabin but water in the servo causing loss of servo failure often required replacement master cylinder too.

The water in the cabin is just as often caused by badly sealed pollen filter housing and on Avants rear washer pipes coming adrift.
