Hi, I share my experience here:
the AOC can several codes: BCM0094/95 cooms cntrl, DEM0006 feed pump, DEM007 hydr. pressure (DEM has about 13 different codes)
I used to get DEM0006, BCM0094/95, sporadic DEM007 and DIM message "anti scid alert", V70D5AWD-06 130kkm.

first I took off the DEM and cleaned temp/press sensor and valve inside, then new oil and filter but got after a while dem007 again.
then I replaced the pump 365€ and no problems since. Have not yet inspected the old pump to find out which kind of failure it is.
getting access to pump is not easy as you need to remove the cardan rear end from haldex.

when asking advise from haldex I got this response:
"1. Without diagnostic tool it is difficult to determine the function of the Temp/pressure sensor.
The sensor needs to show a pressure of 0,2MPa or higher for the system to function. Nominal value is 0,4MPa.
2. Listen to the pump motor while the car engine is running at idle speed. The motor should make a small continuous humming sound.
If it is loud, silent, intermittent or changes sound something may be wrong.
When supplied with power externally at ~5volts the current draw should be about 1-2 ampere.
If much higher something is wrong, if much lower something is also wrong.
