2014 Porsche Cayenne PCM problem

Hi all,

I have a 2014 porsche cayenne diesel. Under normal conditions, when I park the car and turn off the engine, the radio will stay on until the drivers door is opened. At the very least, I was always able to turn the radio on if I was in the car even with ignition off.

Recently, when I park and turn the ignition off, my radio turns off as well and I cannot turn it on unless I turn the ignition to on. Another thing I have noticed is that under normal operations, my power windows would automatically roll up at the press of the button, now I have to hold the button.

I read somewhere, someone had mentioned some sort of battery drain module that my be causing this, but I cannot find any further readings. Has anyone had this problem before or might know anything about it?

Thank you
