So I swapped a facelift R bumper onto my GSW S with my retrofitted GSW fog lights using dremeled out R-line fog covers. This obviously involved removing the front grill and bumper cover. Unfortunately, now neither the fog lights or ACC work (with lights on dash). Before the bumper swap, all coding and functions were working properly with a fog harness from AliExpress and DeAutoLED fog bulbs/resistors/drivers.
Codes:
B121F15 Left fog light bulb open/short circuit to B+ (static)
C110300 ACC sensor misadjusted (static)
U111000 function restriction due to communication interruption (intermittent)
I removed the fog light housings and DeAutoLEd bulb/resistor/driver assembly for a few weeks while preparing the bumper swap. I taped over the fog light harness ends, but we had a few rainstorms during that period of time (maybe the cause of the fog light short?). I did get an ACC light just prior to installing the new bumper when I tried changed traction setting ESC Sport. Hasn’t been working normally since.
Thoughts? I’m thinking next step is a new fog harness and getting the ACC recalibrated under warranty, unless something might be pinched from reinstalling the new bumper. The fogs flicker with low output or don’t come on at all.
