I just bought the Peake Research code reader and think I'll send it back for one of these. It is a really light weight low tech device, two digit display. Anyways, SES light is on, work through its criptic way to read codes and nothing, then go to the reset mode and it does not reset, just returns to "--". Seems like some of these readers are more like the real deal, how do they differ from what the BMW dealers computer set up will do? I have read a bunch of posts about the light weight code readers not being able to do what the computer type can do as far as digging out deeper codes (whatever that means).
Very interested in feedback on the ones in this post, I'm in the market.
