2003 C4S 6speed---33K Check engine light came on the other day. How do I reset this thing? Tried ignition and pressing odometer button. Going to try to disconnect the battery..Any suggestions? Thanks. Is this a normal warning at or around 30K??? Car is running great? Gas cap tight. Do need to change the oil, but I don't think this has any bearing..

 

There's a gazillion things that can set off a CEL. You can run it by a good independent shop (assuming they have the right diagnostic equipment) and get a diagnosis. Most dealers will run a freebie for you if you ask nice. It's just good business. Hopefully it's a simple fix.

I don't know if I'd recommend disconnecting the battery and allowing it to reset. Too many other things in the car are dependent upon a steady flow of electricity to keep working properly.

 

PTparks,
thanks for the 411..I'm taking it in since it's under warranty. Figure it's either the MAF or 02 sensors. Hopefully whatever it is, the warranty will cover it.
