    Passat B7 2.0 tdi estate electrical problems

    Hi All, my first post so be kind
    VW tech suggested coming here to try.
    I have this 2011 passat,
    I have random esp fault with 'optical parking unavailable' indicators not working intermittently but most annoying is sometimes when key is pushed in no dashlights...dead and car wont even crank, sometimes when driving the horn will give a beep without even pressing??
    took it to VW dealer to be diagnosed....it had 8 pages of faults...miss communication with this and that.
    anyway im thinking water ingress and VW tech said the same, he said most likely behind dash as the car has had windscreen replaced and could be leaking?
    is there any source to get hold of wiring diagram or locations of modules to check for water damage?

    many thanks

    Glenn
