seriously man..there is no such thing as adding kerosene to petrol...

its the sound emits by the eps motor assisting when u turn the steering wheel.

yes you are right i just ignore those sound becoz material contracts and expands dependent on temperature, its the law of physic, even ferrari wont deny it ( that's why all their interior were wrapped in leather even on the dashboard too! ) . if it is replaced it will be temporary and the rattle will come back later unless you put something in between the plastic clip and the metal part or on any part that seem to rub against each other with rubber tapes or pads or cloth padding. for people like me, i just diy, it is our own car, can do anything we want rite? if broke, just replace cost money and it is a lesson, but the knowledge and achievement gained is a pleasure. no need to worry on something which is small, it will make your life shorter which is already short. let the car sit in the showroom, i guaranteed wont hear any rattles.
