Hello alfie119611,

There have been some problem with wiring connector corrosion.Your vehicle should be scanned for any failure codes related to the AWD system.If no codes are found check & inspect connector C305 and C305B at the body pass through for corrosion, if no corrosion is found suspect the differential clutch pump actuator check valve as the possible cause.This connector can be found at the

left rear seat floor board.
