2012 135i, help on golf tee mod!

Screw the tee mod, just go into the driver side rear panel in the trunk and unplug the harness as flap defaults to open...

Dredging this thread up as I have a related issue. On my 2010 N55 135i, the exhuast flap control solenoid has become noisy. It buzzes off and on, and it's very audible in the cabin.

So I disconnected the power from it. A couple of weeks later the car threw a code and went into limp mode. When I interrogated it, the code was 2E4C, which is:

0x2E4C
11852
Exhaust gas flap, activation: Line disconnection
The diagnostic function monitors the activation wire to the exhaust-gas flap.
P0475

This causes a yellow limp mode along with the bongs and taking over of the display - it's certainly not a silent code.

Now, I also run a BMWPE, so I don't even need the solenoid. Does anyone have any solutions for how to get rid of:

a) the code being thrown if I disconnect the solenoid
or
b) how to stop the solenoid buzzing? (I can't even find a part number for it on realoem)
