There must be someone who can tell me how the MPE on my 335ix is supposed to work.
I had an MPE installed by the dealer, BMW part, before I took delivery. It is a CPO unit.
I have been trying to find someone who can definitively tell me how to get the left exhaust pipe to open up. The salesman didn't have a clue.
I don't believe that the left pipe flap has ever opened. I checked connections and things appear to be tight. I gleaned from older posts that the flap opens up when RPMs are greater than 3000 and the transmission is in Sport mode or Sport +. Otherwise it stays closed.
Can someone shed some light on how it's SUPPOSED to work?
Thanks
