Hello All,
I have an 09 FL2 i6. I recently installed an aftermarket GPS, reverse, screen, etc in the centre cubby hole. All works well but......There is a high pitched noise present in this unit and the aux input to the existing factory stereo every time a pump on the rear diff runs. This pump attached to the Haldex coupler runs for two seconds approximately every eight seconds when the engine is running.
My question is: Is this normal? The pump noise can easily be heard with the engine running listening underneath the boot space.
I am fairly confident I can filter out this noise and have a few things to try to accomplish this. Just would be handy to know if this is normal function of the Haldex pre charge pump, etc.
Thanks guys, Fitzie
