I have a 2002 Allroad which now has water leak problem at the rear right passanger footwell. I don't know from where is comming from.I need help please.
Also on my CD player it say "error 3" I think i need an CD changer. Someone have one for sale?
Thanks

 

The water is most likely coming from clogged sunroof drain or a clogged cowling drain & ending up in the back floorboard area. What you don't realize is that you have 2" foam pad attached to the carpet which is probably soaked.
Remove passenger seat , lift carpet & see what you have. If there is water in there you must get it out. The abs & tcm modules are located there & they will not be happy when soaked with water.

 

I have the same problem except on the driver side. The entire area under the battery was flooded and then drained into the cabin. There is supposed to be some "nipples" under the battery you can loosen up to let the water out. If you don't, it may flood in the cabin. Now I have to replace the Convenience control module.
