Need your .02 to point me in the right direction. This is going to be long winded and I'll try to be as accurate as possible. I do not have a Bently, but now I feel the need to invest in one.
In my newly acquired 03' tdi wagon. I've replaced everything in the interior due to smelly items and a mold issue. When I first got the car everything functioned as normal. I dismantled the car, but left the wiring harnesses, relay/fuse blocks and CCM. I then reassembled from two good working donor cars, which everything worked in them as well.
Issue #1:
Up until a few days ago my radio and interior lights functioned properly, when the car was shut off and key removed. Now, I have no interior lights. I have to turn the radio off manually (factory monsoon) and my steering wheel controls are Inop. All stalks (cruise and wipers) function.
I've read about a sticky #451 relay, that controls the above. I haven't taken it out of the car yet to look at the coil and see what's going on. I've read about bad clock springs, but they usually affect the stalks also.
Issue #2:
Ever since I installed a new drivers door panel and master control, the only features that work are the hatch release and fuel door release. The donor door panel and master worked fine in the car it came from. I have no window controls to any windows from the master switch, but each window functions fine on it's respective door, except for the drivers window. The child lock feature is Inop also.
The mirror switch is Inop in all directions. My door locks function correctly on each respective door, but if I hit unlock on the master control, it pops the fuel door and does nothing to the other doors. The lock feature does nothing as well.
I've "wiped" the ccm by dissipating via touching battery cables together. The battery was also out of the car for an extended period of time while I was working on it. If I read the ccm via vcds. It shows codes for pass and drivers windows when master switch is depressed, but that's it. I'll get a screenshot later in the day.
Thoughts?
I'm not sure where to start. I've checked my connections in the drivers door and at the ccm. I've also verified my grounds on the crash bar. I am familiar with a multimeter and electrical theory, I'm trying to get some feedback if someone has had the same/similar issues before.
I'm leaning towards the ccm being bad from being in a damp car for awhile, but I pulled the connectors out when I was cleaning the car and they appeared corrosion free. I haven't troubleshot and wiring yet.
