I am interested in this also.

 is this not working? I have registered them before, think it may have been buggy but worked. i did only re register as same battery because i used  factory replacement. did not change the type or size of battery. Ista i believe this is in programming is this what doesn't work?

You have to reset it in 2 different places. You have to register the battery through service (which simply records the mileage the battery was changed at into the ecu), then you have to go through the coding by reading the vin and changing the battery AU rating if it is different from the original (ie A070 is the code for 70 AUs). These are changed on the first screen you get to when you enter coding under vehicle options. Kind of confusing without having access to the BMW codes. Similar to the VW channel programming. I had to do a base throttle relearn on a VW New Beetle today and a Jetta after doing a Fuel Induction service by changing the adaption on channel 060. This tool is great if you can find the coding info on Mitchell, Identifix or Alldata.

 Thank you for sharing!

You're welcome. Everyone here in the states is afraid to work on european cars due to
the lack of user friendly menus compared to Domestic vehicles. When you really dig in
though once you get the basics down for channels on VW/Audi and coding on Bmw
and Mini, it becomes a much quicker process. I've got VAG on my laptop and this tool
can pretty much do everything that VAG can do. I have run full evap/fuel/purge
diagnostics on these vehicles without even having to pull out a smoke machine since
you can literally test each component individually once you have a basic function
channel list.

Today I replaced a purge valve on an 07 Jetta and was able to test the new unit and
run all 7 readiness moniters while the vehicle was sitting in the shop by forcing the
system tests through basic ,channels. That's pretty invaluable in my opinion. I didn't
even have to drive it before it was ready to be emissions tested (though I obviously did
to confirm the repair.) I'm learning that all bugs aside, Its a decent tool.
