I am driving a 525i, recently I notice that either when I am at stationery or when the car is rolling slowly, I accelerate harder the rear will have a knocking feel. But when I wind down the windows try to listen if any knocking sounds, I cannot hear anything. The knocking feel only occur when I accelerate harder during stationery or even car rolling slowly. High speed also didn't feel it. Anyone know what is wrong?
