Could be as simple as a loose gas cap..... a peake reader, off ebay, will help you determine what it is exactly

Gas cap/fuel cap....the part you take off to fill up with gas...

the check engine light will come on if the car thinks there is a problem. If the problem fixes it's self, then it may reset after a number of trips.

e.g. if the gas cap is not on correctly, the fuel system will think it has a leak and the light comes on. nexty fill up, the gas cap is on correctly and after a couple of trips the car decides the problem is resolved and the light goes off.

You can get the error codes read at most auto parts stores for free.

I have a 2000 Z3 2.8L. It has some Dinan addons--insulated intake, strut bar stablizer, tuned exhaust and chip settings. My engine light has been coming on intermittantly for years. Yeah, the gas cap thing. Maybe. I did that years ago and it worked for a while--I guess. Hard to say. I get errors saying my forward O2 sensors are bad. Not. I replaced them twice in one day. Not the problem. There is a problem, however, and I think it's a computer that supposed to be reliable, but isn't. Then the techs read it, believe it, but when it doesn't tell them the truth or identify the problem--they don't know where to begin. As long as the light isn't flashing don't worry about it. I know that's hard, bu tthe alternative is taking it to a BMW dealer and saying: Here look until you find something. And, my friend, that is an exceedingly bad idea.

The Check Engine light can come on for dozens of reasons. Some faults cause driveability issues, some don't. Some cause damage over the long term. Others are mostly innocuous.

Without knowing the fault code causing the light to illuminate, it is nearly impossible to tell you what is wrong or even where to start. Any idiot light is like that - Engine, Trans, brake systems (ABS, ASC, DSC, etc). I don't intend to patronize, but the OP's general question of "Why is my CEL on?" is one I hear quite often from customers at work.

Even if the light went off, there may still be a code stored in the DME's memory which will help troubleshooting.

So yes, you can ignore it if you like if the car seems to drive ok, but having it inspected by a reputable technician would be your best bet. Or, if you are confident, get a code scanner like some have said and tell us what the code is.

My check engine light just came on a few days ago. I hadn't touched the car for days except to add a little oil in the engine. Turns out the oil cap was not seated even though it was on tight. The light went off by itself after a couple of days. You should check your engine with a code reader if the light comes on regularly or if it stays on for very long.
