If under warranty then push the dealer to get the exhaust replaced as its called fobbing off. I don't see the point in disconnecting the flap to try and cure a common fault.

Tim, the "on/off" nature of the valve is crap anyway, even when it works properly. At part throttle it's quiet, then all of a sudden loud, then quiet. Naff really.TitanTim wrote:If under warranty then push the dealer to get the exhaust replaced as its called fobbing off.

I'm unsure what it does on my M135i, I can hear it open after 20 seconds or so from cold start and stays quiet after that, I'm guessing its function is to ensure the exhaust gasses warm the cat quicker. Thankfully mine is nice and quiet but I think I would still push BMW to replace the exhaust if became noisy, something shiny for nothingstuartinzg wrote:Tim, the "on/off" nature of the valve is crap anyway, even when it works properly.

The flap is simply for noise emissions control and comfort.
