Yeah, this seems to be an other genious quality problem of this tool. There is a general
linking problem in the e46,e53,e39 models.
I feel realy punked ...paying this much for a tool that doesn't work proparly...

You can scsn the engine dtc by using the 'check engine eobd' icon at the very first.
This links by autosearching all protocols.

Still, this is just too poor-jumping around functions.

I have had the same problems, my maxisystem worked fine last week on a e46 320ci, went to the same car yesterday (after updating the system) and wouldn't communicate at all even with obd2, kept asking for the 20 pin lead which the car dosnt use, starting to regret buying this system

No I didn't know I was required to make a back up, since I bought the machine I have
been trying to learn how to use it
