Hi, just went out for a drive along the beach on the weekend and went into some soft sand and got bogged (I know, how could that possibly happen with a Range Rover). Another vehicle pulled me out and I drove off the beach and headed for home. After getting up to around 80km/hr on the tarred road a warning cam up saying 'Performance Restricted' and the car wet into 'Limp Mode'. When I got up to around 90k's there was quite a vibration through the car. When I got home I saw sand tracks on the ground where I had just travelled. Turns out that sand had collected on the wheel rims but did not get thrown off after a 25k/m trip. It only started dropping off when I slowed down in my driveway. Hosed the sand off and everything was back to normal. Is this a normal function of this vehicle. A). It is strange that the sand did not get thrown of with normal driving and B). It really limits the vehicles abilities if I had have continued to drive in the sand.
