Mines a 2006 525XI with no problems, as long as you have the N52 which you do your gtg.

Had my computer software updated today for my aux retrofit, got the car back and everythings still working fine! So no worries with dealer visits

Has it affected your gas mileage at all?

I don't know yet, I just installed it on Sunday. However, my fuel reserve message popped up on the way home from the dealership today lol. But it's all good gas is a cost of ownership and if your going to own it, you might as well have fun
