Recently (October), my wife and I purchased an '01 VDC for use as her daily driver. I am not unfamiliar with AWD as my daily is an A4 Quattro.
Today while adjusting the parking brakes on the Subaru, I noticed that turning one of the rear wheels did not turn the opposite side in the opposite direction; rather it spun the rear drive shaft instead. The Quattro system that I am familiar with uses a Torsen differential as the center differential. The torque split is fixed and therefore, no clutch is required. The behavior exhibited by the Subaru would represent catastrophic failure in the Audi.
My question is, is there something wrong with the MPT clutch? I have done some research and confirmed that the MPT is controlled by the fluid pressure in the transmission. Pressure is bled off to bias front torque, with no "bleed" representing 50:50 torque distribution. Am I correct in understanding that in the non-running (no pressure) state that the MPT is not connected to the output shaft and the behavior I noticed is okay?
