A common problem among Malaysian BMWs is that the rubberized component of the door handles melts as they cannot handle Malaysian heat, I am told BMW rubber components use a higher percentage of petroleum to give the rubber component a softer feel. To replace them with originals will come back to the same problem so I found plastic versions for the "Malaysian Right Hand Drive" models at Lazada for RM200 (4 pieces). The material is good quality and compliments the premium quality of BMW cars. Upon installing, the mechanic said the screws that came along with the package so had to acquire long screw, just that installation would be slightly delayed. Job finished, wifey and me are impressed. They fit seamlessly into the car as well as feel as if they are original replacements.
Coincidentally, rain penetrated and rusted the socket of the left rear taillight. I had the same wireman mechanic modify and rewire the socket. The completed job was successful and saved me at least 2/3 cost of getting an original socket.
