"Not having fun at the moment. I upgraded my low line CECM (5K0 937 085G) to a high line CECM (5K0 937 087G Z5Y). The swap itself wasn't to big of a deal, but after recoding the new one to the old settings I had many issues. I spent a while hacking around with VCDS and got almost everything fixed. Currently the problems I can't figure out are:
High beams don't work
Left backup light runs for DRLs
Only right backup light comes on in reverse
Can no longer set footwel light brightness via menu
TPMS light
