first you nee to check and see if your car is referred to as OBDI or OBDII if its ODBI then you start with the car off.. turn the key to run but do not start the engine.. at this point you have less that 5 seconds to push the gas pedall all the way to the floor and press the overdrive button five times... then the check engine light will stay on.. and then blink... next its going to blink out the code for you for ex. blink-pause-blink blink-pause blink blink blink-pause blink n that would mean the problem code is 1231 just Google BMW problem codes and use that dcode to find out what the issue is..

ive been lucky enough to have driven a few of these vehicles. The "check engine light" is usually on the left side of the dashboard indicators and is actually a small message that reads "service engine soon".
the check engine light is for emmissions/exhaust only. the srs light will appear in any case of the seat belt or air bag system since the belts have pretensioners. i would have the BMW dealer to check it out for sure. there were some recalls on some seat belts which might include yours as well.
