Hey folks, I bought a JBale Mk7 to Mk7.5 dynamic tail light harnesses a couple years ago... Coded per the included instructions and have been running the lights ever since with zero issues...
Until today unfortunately. I had my BCM replaced with the high line version. I got the vehicle back home and implemented the coding changes that were provided but I now have a couple issues, maybe all related.
1) With parking/headlights on the tail lights are off (both inner and outer) and I get dash warnings for left and right front parking lights. This is the first time I've had a dash warning for any lights.
2) When I use either turn signal (or hazards) I get the dynamic signal and also the outer brake light flashing with it (but not the spoiler brake light).
Brake lights and reverse lights work as expected. No wiring changes have been made, the only change is the BCM. I have the following BCM adaptation maps which I'm going to compare:
Original BCM with 7.5 tails working
New BCM after dealer replacement
New BCM after making 7.5 tail changes
Wondering if anybody here has seen this before and has any ideas. Picture of the code change sheet is attached. I went through the coding three times to make sure I didnt mess anything up but I will verify that in my admap as well. The blue writing on the side is my original factory BCM coding. Oddly, some of these values were not the same on my new BCM when I brought it home from the dealer.
