Quick reference
Base halogen headlight vehicles (standard on 528i without options) do not use a headlight-mounted control module - verify S522A (xenon) or S524A (adaptive xenon) option codes before purchase
2014+ LCI facelift models use incompatible LED driver modules (63117316217 series) with different electrical connectors and mounting geometry
FRM3 (61359390491) is a separate footwell-mounted body control module; distinguish between headlight ballast failure (no light output) versus FRM failure (lighting logic errors)
Context
The 2011 BMW F10 528i with optional xenon lighting (code S522A) relies on headlight-mounted control modules 63117251905 (left) and 63117251906 (right), which function as both high-voltage ballasts and adaptive headlight controllers. These units interchange across 2010-2013 pre-LCI 5-Series sedans and wagons, including the F11 Touring, but differ from 2014+ LCI facelift LED modules. When sourcing from salvage, prioritize units with visible Bosch casting numbers like 1307329315 over faded OEM stickers. Inspect the multi-pin connector for corrosion—water intrusion through degraded headlight seals is the primary failure catalyst. Installation requires careful transfer of the rubber grommet to maintain IP67 sealing. Post-installation, the module requires initialization via BMW ISTA to calibrate the adaptive headlight range; failure to code will trigger 'Adaptive Headlight Malfunction' warnings despite functional lighting.
