IDK, but I'd sure like an update on what OBD2 scanner/diag to use. So many out there that all do different things and some read more than others when it comes to Crossfires. I tried an Innova 5512 yesterday and returned it. It read my Crossfire VIN and wouldn't read half the systems advertised, and since it reads and checks according to VIN I couldn't force it to check for SLK320 systems which I understand will allow more checks. I'm at a complete loss.
