Default Need HELP: DccD Problems.. Center Diff?? Rear Diff?? Dccd Controller?

Guys!.. I have a crisis with my STI.. Heres the issue.. When I start my car, my abs light is automatically on and Dccd is set on AUTO which is suppose to be used for normal driving.. After driving for 30 seconds, the dccd light is set on RWD and it flashes on RWD.. When this happens, the car feels like the dccd is locked which makes a grinding, rubbing, horrible diff locking sound on turns.. It has gotten so bad that the car would not even move making turns.. Once the car is set from auto to RWD, I am not able to set it back to auto unless I turn off the car.. Once it turns on, it will be set on auto again and then I am able to adjust the dccd to rwd or what not but after driving again it will set back to rwd.. I brought the car to a regular mechanic and subaru dealership mechanic... The regular mechanic says the rear diff is no good.. the subaru dealership says center diff is no good.. Did anybody get this problem before with their 04 sti or 05 sti??? Please I need help.. I got a suggestion to change my dccd controller and see how that goes.. any others?I apologize for the long boring story but I need help.. thanks

Are you the same person that posted on iwsti.com?

It sounds electrical, like the DCCD controller is screwed up. I'd unplug the connector on the tranny (wires leading to rear passenger side of tranny) if you have to drive the car. If that fixes the issue, you know it's electrical. If not, you know it's mechanical.
