I have a 96 Passat. My issue was the battery kept dying. I removed all the fusues and then reinstalled them. Haven't had the problem since. Maybe one was arching and grounding out somehow.

I know it wasn't a battery problem for me, because all the dashboard lights came on, the headlights worked, and the radio worked, even after several days of the car just sitting unable to start. The power windows, interior light, and power locks did not work, and the ignition would not turn over if I turned the key.
 
Here's the site where I learned how to replace the CCM. They have a 1998 Passat, but the CCM and the wires are identical to my 1992 Passat wagon. When I moved the driver's seat all the way back, I could push the carpet back far enough to pull out the large plastic box that holds the CCM, and I can get to the thick bundle of wires alongside the door opening. I still haven't bothered to put it all back together, so I'm driving with a large plastic box on my floor, and the trim strip from the door opening loose.

I see in one of their photos that the part number on their CCM is slightly different than mine. Mine is 1C0-959-799-C-091, and theirs is 1J0-959-799-K-something (the picture cuts off). If the wiring isn't your problem, make a note of your particular CCM part number.

2003 Passat just changed the window reg clips and now the same problem not windows, remote locks, button locks than unlocks, no cabin lights, gas door, rear hatch lock .
 
Did you ever solve yours?

Sounds to me like the CCM. Read message #392 and #397 for more symptoms. Message #401 has a link to a site that has instructions for changing the CCM.
 
Beware, though. The CCM problem can also be wiring. In my case it was wiring, and just kneading the bundle of wires fixed it for me. Which is why I have a brand-new CCM I'm willing to sell. Contact me of you're interested, but thoroughly check the wires first.

I have the same problem with my Passat right now. What ended up being the problem?

Check the ground's in the wire loom leading to the ccm. When you open the bundles of wire, remove the black tape type wrap, and you will definitely see corrosion at the bad joints. I would also check the grounds up on the side wall to the left of your brake pedal.
Finally, check the operation of your door lock on the driver's side. Make sure the electrical portion is actually letting the car know the door is open. (Otherwise I have had it happen, on a Jetta most recently, where the door lock is the culprit, and the car thinks someone has climbed in without opening, and unlocking the door, then the anti-theft kicks in.)
 
Changed numerous Ccm's and respliced many wire looms and most times you can take care of it. Just be careful, and take your time. There are about 70+ wires, spliced down to 30 something, and then down to the ccm plug. So be thorough.
 
Good luck guys!

When I got my Passat tdi 2002, only had a few minor concerns, ie; couldn't open the boot lid using the switch on the drivers door; some of the warning lights on the dash wouldn't illuminate; still the car ran ok. Then the alarm started going off for no reason, thats when I started searching the web for info, took the carpet up to reveal the ccm box & wiring. these were wet but nothing major; anyway let it all dry out for a bit and the alarm started to behave itself. Latest thing is that the car thinks the drivers door is open; took it apart; took the lock mechanism apart resoldered the lock curcuit board; put it back together but the problem remains. Inspected inside the ccm box and all seems well, all fuses checked, all ok, no visible problems with all wiring leading to ccm box apart from it still being damp ( havn't had chance to sort leak out yet ). Disconnected the light in drivers door and turned all interior lights off so battery doesn't discharge but still get the door open sign and beep on the dash when driving ( ironic, cos this didn't come on before this problem arose ). Not sure about next step, any ideas would be welcome lads, cheers
