Someone buy it said that
I bough a bmw scanner 1.4 to get codes out of my car & doing some customizing as well. So far done:

1) get rid of lcm gremlings
2) coded Eu daytime running lights -ON
3) coded TV in motion for free!! not tested yet, because digital-tv required here in north pole
4) readed & reseted error codes +10 times!!
4) coded front sidelights (angel eyes) as additional turn signals when lights off (nice addition!!)
5) changed original obc language to English (this is a good change, if your battery gets old some time and looses the setups made)
5) coded dannish running lights

And many Members of E46forum recommend it.
