Vacuum control valve for the exhaust flap.

[Stormenson]

Hello all ,Any idea where the Vacuum control Valce for the exhaust flap is located on the car z4 e89 35i ?

is it in the trunk or under the car ?

It is on the rear of the exhaust. I believe you can just disconnect it and plug the line to have it open all the time

i want to make a diy DC 12V Wireless Remote Control Relay connection. So i can open and close the valve with remote control.
Found the valve is in the trunk . tested the wiring works fine with button and power from a 9volt battery. I have to wait now to receive the controller.

But it sounds so much better open all the time

Certainly does! Can't imagine why you'd want to "control" it?

Because the car has no cats and the flap is needed to be closed in specific times .

Why? Just out of interest!

Too much noise?
