Below are my list of ergonomics and Man-machine interface issues on E90. :
1. Flimsy design of cup holder
2. Glaring of aluminium panel surrounding the gear panel -issues with insulation of air vent piping to the rear aircond vent and now it 'squeak and rattles' like hell.
3. Rattle from top air cond vent on IP/dashboard.
4. DTC button position beside the central lock button.-safety issues
5. Power window button too far,always mistaken by the rear p/w switch.
6. Door handle rubberize coating-not suitable and started to peel off badly.
7. ICE-Not able to store the display 'LIST' of my MP3s when switch on/off the car. Need to set back everytime turn on the car.
8. No ON/OFF aircond switch. Need to switch off the fan
There's few more to come....
