Engine Code:
M30B30 (for earlier 530i models in this range if applicable, though the product name strongly suggests M60B30 for the later years. Clarification is needed, but the description implies 530i, which in this generation often refers to the M60B30 V8 from 1993 onwards. For the sake of detail, we will assume M60B30 is the primary engine of focus for the latter part of this range, and M30B30 for earlier models if indeed 530i was offered with it.) **Correction:** The 530i variant of the E34 primarily featured the **M60B30 V8 engine** from 1992/1993 onwards. Earlier models (up to 1992) might have had the **M30B30 inline-six** in some markets as the '530i', but the US market predominantly saw the 535i (M30B35) and later the 540i (M60B40 V8) and 530i (M60B30 V8). Given the manual title, it is likely covering the M60B30 V8, and potentially the M30B30 inline-six if it was a common variant for the 530i designation in the target market of the manual.
Engine Type:
V8 (M60B30) or Inline-6 (M30B30, less common for '530i' in US)

Every 15,000 - 30,000 miles (24,000 - 48,000 km), or as needed based on driving environment.
Spark Plug Replacement:
Approximately every 30,000 - 60,000 miles (48,000 - 96,000 km), depending on plug type (e.g., standard copper vs. platinum/iridium).
Coolant Flush:
Every 2-3 years or 30,000-50,000 miles (48,000-80,000 km).

Engine M60B30:
Nikasil cylinder liner wear (in earlier M60 engines, though 530i might be less affected than M60B40), VANOS system issues (solenoid failure, chain wear), oil leaks (valve cover gaskets, oil pan gaskets), coolant leaks (plastic hose connectors, water pump).
Transmission:
Automatic transmission torque converter shudder or failure, manual transmission clutch wear, gearbox synchro issues.
Suspension:
Worn control arm bushings, ball joints, and tie rod ends leading to steering looseness and uneven tire wear. Sagging springs.
