I have a '90 535i that I love but it's been having problems. I used to have three green blocks on the "computer light bar" under the speedometer but now only have one ... What does this mean? Is there a list of codes anywhere?
Also, my check engine light is on and my 535 is idling rough ... How can I find out what the light is trying to tell me?
