XBimmers.com BMW X6 Forum X5 Forum > BMW X6 Forums. I mean looks like sometimes working sometimes not. is getting dirty. If you see right side exhaust got some "sensor" and some tampion : Any ideas gentleman's? Maybe I need to take out something ? or BMW once again did some delirium?
On x5 it seems that only one- left side muffler is working as i see vapor/smoke. that should not be the case. Is it same across all bmw's ??? Not sure. For the 35i the right side exhaust is closed until it reaches a certain RPM.
Also, my right side exhaust has more build off inside the tip, like oil? Can someone tell, tell me something. I'm about to bring it to BMW.
The valve is part of the BMW Active Exhaust and is purely for noise. . And, in a worse case scenario when the alternator isn't working for some .
