This F30 is a real disappointment. When I first received it in Jul 2012, windscreen got scratches due to manufacturing defects. After half a year, problems highlighted in the forum appear 1-by-1:1) Rusty seat frame. 2) One-touch function for driver side window not working.3) Knocking sound from steeringI thought of fixing the above when i send for first service. Then, the message "Drivetrain. Continue the journey at moderate speed. Full performance not available. Have the problem checked by service" appeared two days ago. Today, the message upgrade to "Drivetrain, High temperature...."Call AB Glenmarie, booking is 1 week later. Want to act fast, call AB KL, no one answered the phone!Search internet, found the problem. Bloody hell, buying a BMW, get a proton service + proton quality. :top:
