REPLACED TRANSFER CASE STILL MALFUNCTIONAL

I BOOKED MY X5 FOR PROBLEMS WITH TRANSFER CASE PROGRAM FAILURE AND IT WAS CONFIRMED THE IT NEED TO REPLACED OF WHICH THEY DID BUT TO MY SURPRISE THE ERROR RESURFACED WHEN I ONLY DRIVEN THE CAR LESS THAN 5KM SINCE REPAIRS.<br> I DROPPED THE CAR AT THE DEALER BECAUSE IT COULD NOT OPERATE ONCE AGAIN WITH THE SAME ERROR BUT THEY CALLED TO SAY THE GEARBOX IS FAULTY AND NEED TO BE REPLACED OF WHICH IT WAS NOT A PROBLEM BEFORE BUT NOW AFTER THE REPAIRS - VAALRIDGE IS FULLY RESPONSIBLE FOR THIS NEW ERROR.
