1998 BMW 323i Question: check engine light bulb
Answer #1Oakman December 10, 2009, 18:08Master
In most cases there is one single bulb for the check engine light. There may or may not be a fault code for an open check engine light circuit on your 1998 BMW 323i. On most newer cars the bulbs are not replaceable, the gauges cluster must be removed and sent to a specialty repair shop for bulb replacement. You could try contacting your local BMW dealer parts department and ask if the "check engine light" bulb is "available" and "serviceable".
