Mein Auto: 2007 X3
Just had a complete software update to my 07... What a difference! Car shifts better and the turning downshift hesitation is gone. I'm also getting measurably better gas mileage. Oh, and the head unit now remembers at it has an AUX function.

The update was well worth the $200 charge from my independent. They just spent over $30k to update their BMW diagnostic system, so while it was a lot of money I understand.

Can't wait to dive it again, and to see what the average MPG is over a full tank.
RPM... actually my initials!
