RE: G31 LCI Tail Lights retrofit coding error
BDC was already flashed to 23-03-xx before and I VO coded it with HELC.
After that the lights are working but the error came up. ISTA 4.46.14, ISTA 4.46.11 SDP, ISTA-P 72.0, ISTA Launcher 1.46

RE: G31 LCI Tail Lights retrofit coding error
Looks like wrong wiring (or maybe wrong region for tail lights, dunno). There is no special coding & etc for g31

RE: G31 LCI Tail Lights retrofit coding error
I worked on the tail lights of the 2021 lci model before it was shipped.
If the wiring is done properly as you said, add helc and do aktiv for bl_L®_is _led and it should work without problem. |

RE: G31 LCI Tail Lights retrofit coding error
Gentlemen, I have encountered several cases where adding HELC alone is not enough. Despite upgrading to the latest ilevel, the brake light error often appears. I think BMW still has a bug in their retrofit and they haven't made a good fix for it yet.
In such cases you need to change the value (I don't remember exactly off my head) BL_L (change to CCM_0) and BL_R (change to CCM_0). This solves the problem of brake light errors 100%.

RE: G31 LCI Tail Lights retrofit coding error
Does this also fix the error when starting the engine? The error message brake light defective appears on G31 every time it starts
