Who should I contact about this message that was posted???

" The stereo separation problem was due to a 100 ohm being stuffed in the car output circuit instead of 0 ohm - again, this was fixed on the production line & any units that came back to us had it done as a FCO. "

I want to know if I should fix this on my MK2 or early production MK2a.

Also , is there an "FCO" list that I should look at to make sure my Car Player is "up to date"??

I have already installed the dimmer cap update which solves the dimming problem.
