#10 of 28 Service Engine Soon Light by multivalve

Hi everybody! I'm experiencing a problem aparently with my 323ci(2000) computer. For some reason when I insert the key and turned it to accesories the computer reads the inspection (15000 miles) reading but it is missing the oil change reading at all. As a result after starting the engine the engine service light came on. The problem just started today. I've changed the oil like two weeks ago and my dealer reset the computer readings with my own aftermarket reset tool that I bought on eBay few months ago. Any ideas why my car is not having an oil service reading? Also the inspection reading is not updating the reading while the car is running and always reads 15000.

2002 325i, 54,000 miles. Service engine soon light has been off and on for several months. I finally had the cam sensors replaced and the mechanic told me that nothing else is wrong but the light will continue to illuminate until I have my scheduled 60,000-mi service. It's annoying.

given the age of the car (2001), my bet is that you either have a bad oxygen sensor, OR, a bad catalytic converter (pray that it is not this). Both of these are common reasons for the light staying on with older cars. The cats went out on my 528 at 80K and they replaced them under the emissions warranty (I just made it). Had the Oxygen sensor replaced around 100K. Both times the "check engine light" came on and stayed on. Have talked to others with the same story.
If you do need to replace the converter, try some independent garages. The dealer will kill you on this one.

Same thing happened to our 00' BMW 323i. The Service Engine Soon light turned on when we changed from 87 octane to a 92 octane gas. It also stalled on low idle as well as hard to start. I tried to open the gas lid to release the pressure, but it didn't work. Any suggestions on how to fix it? aside from bringing it to the BMW dealer where they charge so much....... Thanx

Don't see how it can be related to octane.
 
is your gas cap good and tight?
 
Maybe you got crappy gas? Is this from a new station?

the service engine turned off the next day, but after driving it again for about 100 miles it turned on again. The gas is from QT. Any suggestions on how to fix it?

You'll have to have the code read first off with a scanner or code reader. I believe Autozone will do this for you for free.

Anybody knows what PO101 means? Had my service engine light checked at autozone and a PO101 was detected. Thanks.
