Engine Light won't reset?
 

I have a 99 323i and found out today that the reason my engine light won't reset is because it is a transmission problem. So... if your light comes on and does not go off, or you can't get it reset, get your transmission diagosed. It could be the problem!
My diagostic tool was reading double dashes.... no FC...

The torque converter is the problem and I'm going to need to get a new seal.
