I have an 2002 Audi A4 1.8t Quattro. Water leaked in my car andcaused my comfort control module to malfunction(replacing today for $450). After research I figure the water was from clogged drains underneath my battery.

Does anybody have any tips form this process... i.e. things I should be aware of?

Thanks

 

Never mind I should of done some more research I found a process here. Sorry!

Make sure you have the radio code.
Remove the (-) clamp first and install it last.

 

Thanks CH! I've got it.
