pocketlogger
pocketlogger." It is something you can run on a Palm handheld and plug it into the OBD port and it records all sorts of data on your car. I didn't know if anyone has gotten it to work on a E class? It's almost $200 so I was curious before purchasing. Sounds like a neat tool. You can even then read the fault codes and reset the computer yourself.
