Just to let everyone know, the lower back light unit can not be taken off the same way as the upper one. In order to remove the lower one, you had to take off the inner covering before the wheel, had to remove all the mud guards below the car, and then take off the back bumper too. Therefore a much bigger job than the upper one. I find this puzzling as there is a 'red' fog light bulb in there which may need replacing and this would end up possibly taking a garage a couple of hours of labour to change a bulb? Please someone tell me that I have done is completely wrong and there was some sort of simpler way that I didn't pick up
