Frequently Asked Questions
Does this cover the LCI facelift introduced in 2020?
Yes. The wiring diagrams include both pre-facelift G30 production (2017-2019) and the LCI (Life Cycle Impulse) refresh that arrived for the 2020 model year, capturing updated headlight circuits, revised ADAS sensor wiring, and new iDrive 7 infotainment harness changes.
Is the G31 Touring wagon covered alongside the G30 sedan?
Yes. The G31 Touring shares its platform and electrical architecture with the G30 sedan, and its body-specific circuits – including the power tailgate, load compartment lighting, and roof antenna – are documented within this wiring package.
Are the xDrive AWD and 530e plug-in hybrid electrical systems fully documented?
Both systems are fully covered. xDrive wiring includes the transfer case control unit and wheel-speed sensor harnesses. The 530e section provides complete high-voltage interlock loops, on-board charger schematics, and hybrid-specific CAN network diagrams essential for safe diagnosis.
What format is the manual?
The manual is delivered as a high-resolution PDF, searchable by keyword and fully zoomable for detailed diagram inspection. It is compatible with any PDF reader on Windows, Mac, iOS, or Android devices, and individual pages can be printed for bench reference.
