2001 325i sedan 5 speed. Jst bought it last week. Future wife's car. I love it. Just don't know anything about it. I'm a hands on person. The "service engine soon" light came on and won't go off. The previous owner told us that it will come on if the gas cap is closed wrong. I think he's full of it. He probably disconnected the battery to hide the light til we bought it. Anyways, I would like to fix this. I called BMW to see if I can get service manuals like I have for my '01 Dodge 2500 truck. They don't have them, so I bought some service manual CD's off of ebay. Maybe those will help. Anyone know any ways to find a code without a scanner? Thanks, sorry for the long story.
