Just want to double check this - as the car has the hook type wiper arms this would indicate that the flatblades on the car are retro fit style flatblades and this is making me think that in actual fact the car should have the old style blades fitted ??
I have a set of flat blade wipers on my ceed.
An annoying noise is created each time the wipers change direction.
It is not the motor or linkages. It is the blade lifting a few mm and then falling again as the wiper part bends from 45 deg L 45 deg R.
Perhaps another brand would be different, or even the old style blades if they can be retrofitted.
The flat blades however perform flawlessly at speed so that must be reason enough to keep them
One of the biggest problems with wiper blade can be chatter and skipping.. a dirty windscreen can be the problem in many cases for this.. I personally have tried many things to get mine really clean but as yet have not been 100% successful..
