2001 BMW 330Ci Question: service engine soon light
The Check Engine Light (http://repairpal.com/check-engine-light) indicates that there's a problem somewhere in the emissions control system. It's common for a thermostat failure to cause this problem with you car, though the light should not be coming on and going off if the thermostat is dead. Make sure your fuel cap is on correctly, and if the light does not go off for good, take the car in for a diagnosis. - matte
You should really have the computer scanned for the trouble code(s) stored in memory. That will give you a starting point in your diagnosis Are you saying the light is flashing when you're driving? A flashing check engine light means there is a misfire severe enough to damage your catalytic converters (very expensive to repair). If it is flashing, avoid driving it if you can to prevent any damage. - Andy Y
I had this problem. I over-filled the gas tank when I filled up with gas (never fill the tank past the first click of the pump handle). I took off the gas cap and put back on. Problem solved. - Visitor
