Yes - sounds remarkably like my noise and I also can really only hear it with window down. Occurs all the time between 12/22mph and no braking - so sounds plausible it is tied in with front motor as Dealer Technician advised. However, surely it is unacceptable on a £100K Porsche and why can't...
My 2020 4S has a consistent 'brake squeal' noise from the front nearside area between 12mph and 22mph. Dealer explained this was 'normal ' and comes from the front motor. Seems unlikely - anyone experience this ?
