BMW

Etime i start my2000 bmw 323i car the oil sign the dsc sign brake and abs comes on and then after a while oil light goes off and then when i start driving all shut off somebody know if its serious

If its a yellow oil light and the oil level is ok (on the dipstick)the oil level sensor may be bad, those things fail often. its a simple repair on your car, just 3 10mm bolts on the bottom of the oil pan. the older e46 3 series did not have any reinforcement plate covering it so its easy to access. dsc and brake lights will come on if the battery is low, so thats something to check. if the brake and dsc lights stay on however it could be a bad dsc module and/or wheel speed sensors. hope this helps.
