Location of Immobiliser module???

There is a little bit of "fog" on the inside of the front screen when it rains, so moisture is getting in somewhere.
The carpets are not damp.
We have had the wiper cowl off and it is relatively dry in there from memory. I will check with the kids as they pulled it off.
The screen LOOKS factory, although does not have a "VW" logo on it.
Perhaps it IS around the screen as it does fog up a bit. Needs a bit more investigating me thinks!
Thanks for your advice also!
Cheers.
