Hello, after upgrading from CDR24 to PCCM+, the main speaker on the right door started making a popping noise every few seconds. The noise only goes away when the head unit is turned off and is persistent even when no audio is played. I have attached a video recording to this post. Has anyone else ever experienced anything like this?

yes, when listening to a more up-tempo version of McCartney's "Blackbird". arguably, one of the best tunes he ever wrote.

For anyone experiencing this same issue in the future: Porsche gave instructions to swap the left and right speakers to see if the issue would follow the right speaker and it didn't, so the PCCM+ unit is defective and Porsche is going to replace it.

Final update:

So the replacement PCCM+ unit came and unlike the first one, it came with this thing, PCG.642.580.00. With it plugged in, the ticking was present, but it went away when this was unplugged. With this unplugged, all functions still work normally. Spoke to Porsche and it seems like this is part only matters if you have the upgraded Bose sound system, which I do not have.

I've driven the car for a week now with one extended 3-h drive and I didn't notice anymore ticking/crackling, so I think this is now resolved.
