Check this by selecting 'Sport' mode and accelerating steadily. | Observation: Notice if there is any hesitation or 'shudder' in the drivetrain, as the transfer case can occasionally exhibit some roughness in higher-mileage examples.
While driving at low speeds, turn the steering wheel to full lock in both directions. | Observation: Listen for any faint clicking or clicking sounds which may suggest the CV joints or steering rack bushings are showing signs of their age.
Check this by inspecting the digital iDrive service history for gaps. | Observation: Ensure the oil changes have been consistent, as the B47 engine relies heavily on regular lubrication to keep the turbocharger and timing chain healthy.

Estimated repair costs if issues arise
In some B47 engines, carbon buildup can occur over time. If you notice a loss of power or a warning light, it's worth having a mechanic clean or replace the assembly to keep the engine running efficiently.
While BMW often calls this 'sealed for life,' many specialists recommend a fluid and filter refresh to ensure smooth shifting as the vehicle reaches higher kilometers.
Depending on the roads the car has travelled, the suspension components may eventually soften. If you notice the handling feeling a bit 'bouncy,' you might eventually need to budget for new shocks or control arm bushings.
