2010 VW Transporter T5 All Wheel drive

[Berntsk]

Hi... Have a T5 with a problem, the Haldex system is lock the axle when i drive slowly, axleration and driving uphill.
used VCDS there is no fault code, but when i try to run output-test on the hydraulic pump on the Haldex, so there is no activity on the pump and no voltage.
but i can read the temperature on the haldex oil and temperature on the plate.
so what is wrong?
could there be a problem with the data module on the haldex ?

Please post an Auto-Scan so people can see exactly which Haldex module this vehicle has. There have been quite a few different generations of them, and different variants within a generation as well.
