Driving to work today, noticed the 4WD torque-split gauge doing weird things. Taking off from traffic lights (very sedately), the tacho would reach 1000 rpm, and the gauge would jump to 35, and stay there until about 3000 rpm, then drop to 0.
Also, reversing into a parking spot, the car's behaving like its got a locked diff (couldn't tell which end - F/R).
So, what's going on?
