So I just got back from my smog test. Everything was going fine until the guy asked me if my car was an M3. I replied "no, it's just a regular 325is," after which he made a face and walked away. He then calls me in to tell me I failed because my check engine light (which I thought was just the flashing "check" light in the center of the cluster this whole time) never comes on. Everything else was within spec, but he said he couldn't pass me because the light was broken. Apparently M3s don't have a check engine light which is why he asked.
So how can I fix this? The cluster is a Motometer unit out of an '88 325is, but the speedo/odo is the one that originally came in my '89 (made by VDO). Could the bulb just be burnt out?
