I own a 1998 Z3. The "Check Engine" indicator went ON couple of days back. Sick of taking it to the mechanic, I ordered a "R5/fcx Ii Fault Code Tool" through BimmerZone store to do some preliminary investigation. I am expecting it to be delivered anytime now.
However, yesterday the "Check Engine" indicator went OFF by itself. I am not sure what to make out of this. Does it mean that everything is fine or is there a latent problem thats just waiting to show up? Now since the "Check Engine" indicator is OFF, if I run the scan tool will it tell me anything? Any responses greatly appreciated.
