Well it is going to look like I have the oldest 35D here, but mine is 2009 X5.
Did not have any issues whatsoever ( with the engine or trannie )
They ( BMW ) just did my recall on the mixer ( yeah that's what it is called ) it is placed in the exhaust system right before the urea injector, neat stuff )
full exhaust system from the cat down. EGR, and something else.
I still love mine
