2003 CCM or BCM diagnostic & replacement tips?
Hi all,
I have a 2003 Audi A4 Quattro and am having a number of problems. I could use your help diagnosing which part of the car is broken and if I can fix it myself without the Audi dealership. The moon roof drain was clogged so water pooled in the drivers side feet areas. I am trying diagnose whether my problems are due to a broken Body Control Module or a Comfort Control Module. Please help!
My car's symptoms:
Things that don't work:
- windows
- interior lights always on
- battery drains
- Temperature controls (doesn't work at all, always off)
- key fob no longer works with locks
- electronic locks
Things that do work:
- front lights
- lights in speedometer area
- electronic seat movement (forward/backward & up/down)
- locking driver's side door with key
Thinks I have not tested:
- windshield wipers
- blinkers
- audio system
1. I looked youtube and saw that the Comfort Control Module is under the driver's side foot area, so I am guessing this is probably what it is - but I have also seen online that they symptoms might also indicate that this is a Body Control Module issue. Can you diagnose if it is the BCM or CCM from my list of symptoms?
2. Can I buy a used replacement module to replace the broken one?
3. Does a replacement BCM or CCM need to be programmed by a dealer or is it "plug and play"?
Thanks for your advice!
