Passenger side exhaust

Phaeton · 09-10-2016, 12:23 PM

From what I've seen the passenger side rear exhaust has a valve in it that apparently opens and closes. I noticed it when washing the X1 and at first I thought it was just a fake exhaust tip, but noticed the valve.

Anyone know when the passenger side exhaust opens?

If it's the same as my M135i was then after the warm up cycle. It's all to do with getting the car up to temperature / emmisons

Hi. To elborate, the valve opens in conditions like when the engine is cold and is warming up, when the vehicle is in Sport mode and when the car is floored. Most modern BMW's feature this now and some have modded the exhaust flap to be open all the time for a more aggressive tone. Hope this helps.
