Ugh, these thread notifications keep going to spam. I decided to try a newer panel ($30 shipped from eBay; 5GM 907 044 H from a 2019 Jetta). It didn't change my recirc issue, which I ultimately solved with coding, but it does interact correctly with the MIB2 infotainment screen. The A revision didn't display the temps and had some other quirks on-screen (not a huge deal, but nice to have things working as intended).I would love to take a peek at your coding info. At a quick glance at your earlier posts, it seems like you bought 5G0907044BD? That's the one I got, too. It looks like Goodbar's unit is 5GM907044A?
This seems plausible. Good thinking, as always.
For those upgrading — other than early Mk7s with MIB1 — probably worth getting something newer than the A rev.
