My code reader has been invaluable for my 993 and 330i. Even without a CEL you can fail smog if your readiness codes aren't reset, which you can only see with a code reader. That's happened to me twice with the 993 and it's a real project to get them reset. But I was able to do it and got through emissions in VA and AZ. When I called around to some shops, they either didn't know what to do or told me I was just SOL. The BMW reset procedure works on 993's too. I called a local shop and told him about it, told him he could easily charge two hrs. labor for it. He was very grateful. I don't know why it's such a well-kept secret, but it does work.
