Important application-state rules proven in this part

1. M57D30O2 is not one universal 235-hp/500-Nm row: BMW technical sheets publish E60, E65 and E70 states separately.
2. N52B30O1 is split between the 130i and X5 calibration.
3. N62B48O1 is split between standard 367/490 and E70 X5 355/475 states.
4. An unchanged badge/output does not erase a displacement revision: E46 318d 115 hp changes 1951→1995 cc.
5. M56 does not inherit M54B25 power without a dedicated regional primary engine source.

DATA CONFLICTS / source flags

DC-P20-001 — BMW 745d

• contemporaneous BMW 2005 launch material: 4,423 cc V8 diesel, 220 kW/300 PS, 700 Nm;
• BMW Frankfurt 2005 update: 242 kW/330 hp, 750 Nm;
• BMW Belux later technical sheet: M67D44, 4,423 cc, 242 kW/330 CV, 750 Nm;
• current BMW Group Archive 745d card presents materially incompatible engine figures.

Decision: contemporaneous launch/update + technical sheet define canonical engine states. Archive page retained as conflict evidence.

SF-P20-002 — N55 suffix chronology

The N54→N55 architecture switch is documented at launch, while the exact N55B30M0 suffix is confirmed by a later BMW technical-data sheet. The code is therefore marked primary-confirmed, with source chronology explicitly disclosed.

Still open for редакционная глава+

• M56 dedicated North American engine-component output sheet;
• complete M47/M57 suffix chronology by market and build month;
• option-843 reduced-power factory states as a separate homologation audit;
• N74 2009/2010 launch boundary;
• N20/N26, full N55, N57, N63/S63 and B-family modular engines;
• S65B44 special-edition branch;
• hybrid/48V component/system normalization as its own Stage 4 sub-ledger.

Stage decision

Stage 4 = IN PROGRESS / PASS for continuing to редакционная глава.
