The wipers on my X1 are noisy. They produce a loud “thud” both at their rest position, and also at their maximum stroke position. Needless to say, the continuous "thud...thud...thud..." soon becomes irritating to all occupants. Lifting both wiper blades eliminates the noise completely. Lifting one, and then the other indicates that there is no difference between blades. The sound reduces somewhat if the rain is very heavy. The stroke itself is silent, the "thud" only occuring at the change of direction. The blade stroke is set correctly and the blades do not contact the screen surround at any point. Thus all suggests that the noise is definitely blade related as opposed to the drive mechanism. But the car has not even done 1500 miles so the blades are effectively new. Before visiting my dealer I would be interested to know whether this is common to all X1s.
