2013 xc70d5 AWD disabled Service needed

[zimba]

Hello, MY 2013 only 35000km gives an error code DEM-P188971 on Vida and display says that AWD is disabled...need service...but then a day later it works again. This happens after some hours of drive when car is warm. I Think 2013 has generation 5 AWD Haldex and have Heard of some problems with oilpressure pump??
any comments??

same problem here, power on the pump is ok, but stil the message pops up "service needed for all wheel drive"
Vida comes with the same code: DEM P188971

But know one came up with an sollution yet?
