Your VIDA data/DTCs point straight at the pump circuit. DEM shows P1889-14 “Oil pressure pump performance – short to ground or open.” and “Coupling inactive or failure (open),” pump current = 0 mA with no sound when you run the pump in VIDA. That’s classic dead pump / open connector / broken wire, or a failed pump driver in the DEM. The SAS fault wouldn’t cause those readings, it can limit AWD while the fault is active, but once SAS is fixed the system should come back if the DEM/pump are healthy.
Next steps I’d take are:
- Unplug the 2-pin pump connector at the coupling and ohm the pump: you should see roughly ~0.8–2 Ω.
- Open/infinite = bad pump.
- Near-zero (<0.3 Ω) = shorted pump.
- If resistance looks OK, briefly power the pump directly with a fused 12 V jumper (1–2 seconds, don’t run it dry).
- No spin/no whine = bad pump.
- Spins = wiring/connector/DEM driver issue.
- While commanding “Activate pump” in VIDA, back-probe the pump connector: you should see PWM voltage and ~4–7 A current on a healthy pump. 0 V / 0 A with good supply to the DEM usually means the DEM’s pump driver MOSFET is toast (common).
- Since you serviced the Haldex ~3k ago: if that was fluid-only and the filter/strainer wasn’t changed/cleaned, the pump can overwork and die. If the pump does run but pressure never builds, pull the pump, clean the pickup screen, and replace the filter and seals, then bleed with VIDA and top up.
So first, verify the prop shaft really should be turning, rule out the angle-gear/collar. If the shaft does turn, your screenshots + silent VIDA activation + P1889-14 make the pump (or its wiring) the prime suspect, with the DEM driver a close second if the pump ohms out fine.
If you want numbers after repairs: in VIDA you’ll typically see non-zero pump current during activation and “AOC/DEM status: Normal operation,” and on a lift the rears will drive when you give it throttle.
