Seat garage fixed the rear suspension noise, they advised that some screws needed to be tightened as they get loose after 10,000 KMs .
the B-Pillar noise, I sorted it
removed the B-Pillar plastic part inside the cabin where the seatbelt is located and there are 2 metal clips in the body of the car and they are very loose , so i just stuck a peace of hard paper to check if they are causing the noise and I was right
