•Pull the full service history and confirm oil changes were done at 10,000 km or shorter intervals with approved LL-01 spec oil
•Cold-start the engine and listen for timing chain rattle in the first 10 seconds before oil pressure builds
•Scan the ECU with BMW-specific diagnostics (ISTA or equivalent) for all stored and current fault codes including VANOS, misfire, and boost faults
•Check the car's VIN against BMW's official recall database for the engine bay wiring harness recall and confirm any required work was completed
•Inspect both air filter housings and check the condition of all visible turbo inlet and intercooler hoses for cracks or loose clamps
•Check coolant level, condition, and inspect the reservoir for cracks; look for any signs of oil in the coolant or coolant in the oil
•Have all 12 ignition coils tested or swapped to confirm no early degradation, since a full set replacement is a significant cost if neglected

Engine bay wiring harness / potential fire risk
Certain 2009-2011 BMW 7 Series V12 models were subject to a recall addressing an overheating wiring connector near the engine bay that could, in rare cases, lead to a short circuit and engine compartment fire.
