3.0L N52 (730Li) - Straight-six naturally aspirated luxury
Petrol
While idling in Park, observe the engine responsiveness. | Note: In cars of this age, it's common to consider the health of the VANOS solenoids. If you feel a slight hesitation or inconsistent idle, it may be worth checking if these have been serviced or cleaned recently.
Operate the iDrive controller and secondary buttons while parked. | Note: These complex electronic systems occasionally show their age. Ensure the screen is clear and the controller dial doesn't feel 'sticky', as internal electronic fatigue can occur over long periods of use.
Check the condition of the suspension by listening closely over small bumps. | Note: The F02 platform is quite heavy, and as these age, the control arm bushings or air suspension components may show signs of wear. Listen for any light knocking sounds to gauge the current health of the suspension.
Inspect the panoramic sunroof operation during your visit. | Note: It is quite common for the drainage channels to require a periodic clear-out to ensure the interior remains dry. Testing the motor operation and checking the headliner for signs of dampness is a prudent step.
Consider a full refresh of the cooling system components, specifically the water pump and thermostat, as preventive maintenance.
A good time to inspect the transmission fluid and filter, even if the service manual lists it as 'sealed for life'.
Keep an eye on the valve cover gaskets and oil filter housing gaskets, as they may begin to weep slightly with age.
Prioritize a pre-purchase inspection from an independent BMW specialist who knows the F02 chassis well.
Ensure the service history shows regular oil changes using high-quality synthetic lubricants.
Check that the coolant has been flushed within the last few years to keep the N52 cooling system happy.
Verify that the battery is healthy and of the correct type, as the 7 Series is very sensitive to voltage drops.
Take note of the tire wear patterns; even tread wear often indicates a well-maintained suspension setup.
Estimated repair costs if issues arise
Given the luxury nature of the 730Ld, the air struts may eventually need replacement. If this component needs attention in the future, it involves sourcing quality parts to ensure the ride quality remains as intended.
The cooling system components are hardworking items. Depending on the car's history, you might eventually need to budget for a new water pump and expansion tank to avoid future overheating.
It is quite typical for BMW engines of this generation to develop minor oil leaks around the valve cover or oil filter housing. If this needs attention, it is a standard but labour-intensive task.
