Mike - I appreciate you chiming in, but I have to tell you, on 2 separate days, where that same computer read other BMW's in between - MY car was not able to be read - it didn't recognize my VIN nor was it able to perform diags. It is what it is, this really happened. I'll be back there to get more work done soon enough, but I had really thought that there was a real issue - but my car is fine (other than the typical emission codes due to the cats being removed).
