Yeah, I don't know what a 4.8 would show.


You can buy the CarChip for about $100 to $150. You just plug it into the OBD-II port and then later download the data to your computer. It hold about 40 hours of data I believe, depending upon the sampling interval you choose for the parameters. Most the the data capture works with BMWs, but many of the parameters do not apply to diesels and are not logged, e.g., O2 sensor data, It will also log OBD-II error codes which can be read when downloaded to the computer.

I have an older version, but here's a link to the latest:
