My wife's 03 325i has been back to the dealer 3 times for the freakin' Service Engine Soon light. It's back on again.
This is turning into a pain in the neck. She's gonna set an appointment with the dealer to have it checked out and have her first oil change ... it's been 18 months. You think she listens to me when I tell her to have the oil changed no later than 12 months ???

I have my new 325i for 6 months now. Today in this cold weather of -30, the Service Engine Soon Light came on. It stayed on for about 10 mins after which it stopped.
Is this something normal to happen in this cold weather? Something i should worry about?
Thanks a lot.
Since it's only 6 monrths old, I would have it checked buy the dealer. And because it was so cold... I would lean towards the the converter not heating up fast enough and setting a fault code which would trigger the light, the the ecm turns it off after it sees the proper signal.
I just went to the dealer to see what was the thing with the SEC light and they found out that some of the ignition coils were not working properly, which was causing the engine to misfire, and hence causing the service engine light to come up.
Therefore I would take your SEC lights to be on seriously enough and not just rely on it being just a result of cold phenomenon. It could be more serious than that.
