You need a OBD 1 system or take it to a mechanic to check.
The OBD2 system will not BLINK codes for you. It requires a engine scanner to read the codes. HAVE ENGINE SCANED. Some parts stores will do that for free.
With a scan tool, or try turning key on, off, on, off, on and counting the blinks of the check engine light. blink, blink, blink, pause, blink would be 31.
On some if you turn key on, off, on, off, on. The check engine light may start to flash the code. blink, blink, bink, pause blink would be 31.
There are dozens of codes. Be specific as to what code you are getting.
yes, and what codes are you asking about "check engine" or anti lock radio codes?
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..
check for engine codes- it could be that there is a bad o2 sensor or something.

You can't, you must use a scanner.
Have vehicle scanned to determine the problem and have codes cleared
You have it checked for codes and diagnose the cause of the code.
The check engine light comes on at start up for a bulb check. If it stays on with the engine running the computer has detected a malfunction. You need to have it checked for codes.
