Hi, i own a bmw e92 320d from 2010

It has front and back pdc sensors. Recently i installed a tow hitch with aftermarket electronics. After installation my front pdc and button stopped working. Also, when i put it in reverse i see the sensors working but i dont hear the pdc sound.

I have checked without the tow hitch electronics but the problem stays.
I checked all the fuses aswell and thats also ok.

Any ideas?

Thanks.
