3L I6 Naturally Aspirated N52B30 (240hp).
Quick reference
Option code dependencies: Must verify donor vehicle has matching options (S322A Comfort Access, S323A Soft Close Automatic, S674A Harman Kardon) to ensure correct pinout
LHD vs RHD incompatibility: Mirror control switch wiring differs between left and right-hand drive vehicles despite identical physical connectors
F07 Gran Turismo platform uses different harness routing lengths and is not interchangeable with F10/F11
Context
The F10 generation BMW 5-Series sedan utilizes a complex door harness integrating power windows, mirror motors, and Central Comfort Locking (ZV) controllers. For the 2011 528i with N52B30, the front left harness typically corresponds to BMW part number 61 12 9 199 671, though units manufactured after March 2012 often carry superseded number 61 12 9 223 831. When sourcing from salvage yards, target 2010-2013 pre-LCI sedans or F11 Touring wagons; avoid 2014+ LCI donors as the mirror connector pinout changed to accommodate LED turn signal updates. Critical inspection focuses on the rubber accordion boot at the A-pillar hinge—flex the harness while testing continuity on the heavy-gauge window motor leads (pins 3 and 6) to detect conductor fatigue. Verify option compatibility: vehicles with Harman Kardon Logic 7 (S674A) require thicker speaker leads, while Comfort Access (S322A) models need intact 2-pin capacitive handle sensor wires that commonly break at the crimp points.
