If anyone has complained about rattles from the doors and the TASS has fixed it, just check if this is how TASS fixed the rattle. Black cello tapes wound on the rear door locks Door pads were opened and oil/grease was applied somewhere inside. After some time, the oil/grease melts and starts flowing down, making all the dust and dirt stick to the bottom portion of the front door. Also, the pin that locks the door pads has become loose now. They used brute force to open the door pads. You can see marks of screw driver or some other tool at the bottom portion of the front right door. Visible only if you kneel down and look upwards. All these were noticed after the last running service at Concorde.
