Dropped off the car at the dealer last friday and picked it up later that night. My SA told me they filed off the 4 edges/corners of the pads as per service file. They test drove the car and the brake squeal was still present. So now they opened a PUMA case, and I have to wait for a call from my dealer for further instructions.
Basically the same thing they did on fellow forum member Shep1's post here:
So now its a waiting game, no fix, and brake squeal still wakes up the neighbours at night...
