E46 Check Oil light

[paksu]

Boss, do u think we can service the sensor first ah b4 change it and torn our pocket for rm360? I guess that why this problem happened is that... when the sensor get too dirty due to selldom oil change etc... there is a dirty black thin layer cover the sensor part that is touching with the oil and that make the sensor less the sensivity so that the sensor will give a wrong signal to system... the function of the sensor is to check the present of oil, when it's get dirty it will ignore the present of oil at a first step for few second and back normal when much oil contact with it... i will try service mine first but where is the sensor located ahh?

tq

I ended up changing the sensor before I sold my car for the new owner. Did it at AB, which was about RM800 + oil change = RM1.4k. The oil costs in AB has risen over the years, used to be Rm200+ now its like RM500+. Anyway, outside shops will do an non-BMW part oil sensor change, where they collect your oil and fill it back into the engine for ~RM360. If you refresh your oil it'll probably be around Rm500-600 in total. Best to change it during a scheduled oil change.

My advise, while its harmless, you'll likely want to change it if you are planning to sell the car one day, so might as well just change it and enjoy driving the car without the yellow light coming up for the first few seconds of driving.

i think is your car engine oil condition, oil level low or oil level sensor faulty.
