I was driving along today and check engine light came on. This happened recently about 4-5 months ago, and nothing seemed to actually be wrong.. just a routine maintenance sort of thing. Turned the light off through directions given by someone on this site. Now I'm just wondering if this is something that should be a true concern. Nothing seems to be wrong, nothing funny in the last few weeks that I can recall. I'm getting it checked tomorrow, just interested if anyone has a similar story that may be helpful!

I haven't had this happen in my bimmer yet but I bought a OBDII code reader years ago. It is a cheapie from Harbor Freight. I think I paid $40. It will also turn codes off. The last time I used it the problem was my wife hadn't put the gas cap on well. These simple readers work on all cars sold recently in the U. S. and are worth having IMHO.

A cheap OBD II scan tool won't work on a '93. A Peak Research R5 tool will work on a '93.

Clearing fault codes without knowing what caused them is not a good idea.

+1

The fault triggering the light may be something minor but the code could also help you identify a component that is failing. If you ignore the problem it could lead to more serious damage.

eg - O2 sensors going bad - you ignore it, the car runs rich and destroys your cats = $$$ repair.

What about running into a check coolant warning? It's happened many times, I've checked it several times... seems to be fine. This, and a brake light fail warning are the only other warnings I've seen since owning the car. I haven't seen a brake light fail in a few months though.

Check coolant could be a faulty sensor. I think its in the cap on your car. Intermittent Brake light warning could be a corroded socket or connector.
