Hi

Mine is a 1999 Passat V6 5spd.

The problems are:
Gas door no longer works, got bad slowly. I just leave it open.
Power mirrors no longer work.
None of the 4 power door locks work. The truck lock works fine.

Locking with physical key or pushing the buttosn down work fine.

I've removed the CCM from under the floor and it does
not look corroded. I cleaned up the contacts but no change.
Is there a bench test for the CCM?

I scanned yesterday and got:
Control Module Part Number: 1J0 959 799 AJ
Component and/or Version: 63 Zentral-SG Komf. 0001
Software Coding: 04096
Work Shop Code: WSC 05311

So, should I spring for a new CCM or should I start tearing the doors
apart looking for cracked solder joints on the door lock mechanism?

Thanks in advance for your insight.

I had exact same problems as you have indicated. I removed the ccm and found no issues with the unit itself.

Followed the wire bundle to where all the tape and welds are and had approx. 32 wires that needed replacing due to corrosion at the solder points.

Took about four hours and some waterproof connectors - and all is back to normal.

Good luck

I agree with so much gone wrong, it's got to be a central item like the CCM/wiring rather than any one or more of the door latches.

I pulled the floor up again and untaped the wires. Just as the suggestions said, the wiring harness was bad.
One connections had completely corroded through and fell apart.

All now works fine, door locks, power mirrors, and gas door.
Thanks a bunch.

The only issue now is a VAG-COM scan on the Comfort Module
indiates the DTC Data Bus is in Emergenry Mode. Heck it works, so that's good enough for me.

Thanks for the info.

Four hours down by the floor soldering? Sounds fun :p. In all that time, how did you keep from accidentally burning your interior.
