Audi Repair: 2000 Audi A4 quattro remote unlock system, audi a4, remotes

Question
For some reason on a rainy day the unlock from my remote stopped working i had 2 remotes and they both just ceased to work i think it is something to do with the receiving end i i changed batteries and still nothing. Any suggestions and where can i find the receiver? Thanks.

Answer
hello
check the module itself, I have seen many of them getting water inside and one day it will just not work. The module/pump is located inside trunk , in the right corner .You will have to remove trims. Pump is going to be inside rubber or foam. I can  see water inside. Somehow  the drain gets clogged and water collects just where the pump seats.
good luck        Greg
