Gathering codes on a BMW before 1995 is done using the check engine light. When the code gathering is activated the check engine light will flash on and then off, count the blinks. The first set of blinks will give you the first digit of the trouble code. After the first set of blinks the flashing will pause and then restart blinking, this will be the beginning of the next code digit and so on.
