comfort control module by passat02

Hi all. '02 Passat, 65K miles. Key remotes inoperable. Dealer replaces batteries, concludes keys not communicating with comfort control module.
 
Drive home, park. 2 hours later, car won't start with master keys or valet key. Door locks, windows, interior lights and trunk release inoperable. Battery is connected and powered; stereo, a/c, exterior lights, wipers all work.
 
Fuses appear ok; pulled and reinserted each. Lifted carpet and found no visible evidence of water damage or residue in or around the CCM.
 
Any comments on these issues or reliability of CCM in general appreciated.

the same thing happened to my 2002 passat...the problem was leakage into the passenger side where the ccm is located. the leakage was due to drain clogs under battery, totalling wetting and distroying the pollen (?) filter and causing the leak....design flaw. They did replace the ccm and all worked fine after that...same same issue with drainage problems for passat

Has this been resolved. I have a 2002 W* with 55000 trouble free miles until yesterday. My problem is similar, only worse:
I have an electrical “Bug” with the following symptoms:
1. Fuel gauge does not work (i.e. indicates “empty”) and as a result the trip computer “Miles to Empty” does not function
2. Power seats work but the memories do not function.
3. Radio works but does not turn off with the key
4. No indication of Audio system status in the top of Driver Display
5. Neither key-fob remotes function.
6. Power door locks do not work.
7. Power windows do not work.
8. Power mirrors do not work.
9. No Air-Conditioning.
10. No Temperature input to Auto A/C (Indicates °C not °F)
11. Trip Odometer in Speedometer doesn’t work (resets itself)
12. Trunk Release does not work (fuel door release does function).
13. Main dashboard lights work but all auxiliary lights (center console, radio, door switches, steering wheel lights, etc.) do not work.
14. Auto-Transmission works but when it is placed in manual, transmission doesn’t shift on command.
15. Horn doesn’t work.
16. Clock doesn’t keep time
17. Interior lights do not come on with door opening
18. Dashboard gauges all go to zero (Intermittent Problem-two occurrences, lasting seconds)
19. Car fails to Start
Items have failed in sequence over three days.

I'd say your CCM is wet and possibly your TCU, too. Both located under the carpeting...

Note that this problem has been resolved. The CCM was completely burned out. This was caused by the Fuel Control Module located in a well in the trunk under the spare tire. When the car was detailed, the detailer got water in the trunk and flooded the Fuel Control Module. This caused all item to fail.
 
The detailer ended up paying the $1400 repair bill.

Wow! Glad the detailer took responsibility without a hassle (right?). Thanks for letting us know - altair nailed it.

thnks...but can u clarify ..passenger or drivers side??...when my passenger side flooded...I was told the ccm was fried and maybe the trans module???? its a passat GLX 6 cylinder 2002 w/ triponic trans. My friend just drove and said noticed when slow down to stop...it seems to down-shift the last two gears before stopping.. I now notice as well..the down-shift is very noticeable...maybe it has always been there, just didn't know it. If I do a hard stop...I don't feel the downshift. Is this normal?? or is there something wrong with my transmission? any suggestions???? to a) PASSANGER OR DRIVER SIDE FOR CCM AND TM and b)does the noticeable down shift while final slow down to stop mean something is wrong with my transmission or tm. My dealership was not too helpful.
thanks.

I believe the CCM is on the driver's side and TCU is on the the passenger's side (assuming your vehicle is LHD).
