Animated tail lights - project opportunity

[mystermykee]

Well, I've spent about the last month trying to get this to work. Here's where I currently stand.

Wired all 4 tail light pin 3s to the BCM2 C5 LIN on black 32pin connector (same bus as the kick sensor/siren, which both work fine). Coded BCM2: all four IntelTailLight bits = installed, can_lin_signature_routing = active, and even ported the MY25 light channel dataset (7202) into my gen1 coding — car took it all.

Results so far: BCM2 is definitely polling the lamps — I get 4 active "tail lamp no signal" faults that won't clear, and PIWIS now shows Rear Light Left/Right 1/2 UDS nodes plus per-lamp coding records (all unreadable since the lamps don't answer).

So software side is done and verified, lamps just won't talk (unless there's something else I'm missing). I'm beginning to think the gen1 lamps didn't actually ship with the necessary hardware to do such animations, even though they have LIN connectors.

And if I click into one of the rear light UDS modules....nothing.

I've also inquired about the .2 ECE/ROW taillights sets and the two places I've called don't have an in stock date from Germany listed--my guess is all the ones they have are going onto new builds.
