Petrol
While at a standstill with the engine idling, listen for any light ticking or erratic vibrations from the engine bay. | Note: The B48 engine is generally robust, but monitoring for unusual idle harmonics is a good way to gauge overall health.
When accelerating from a stop, pay attention to the gear changes for any hesitation or clunking sensations. | Note: The ZF 8-speed transmission is excellent, but checking the shift quality ensures the transmission fluid has been cared for.
Check this by turning the steering wheel full-lock in both directions while at low speed to listen for any clicking noises. | Note: This can help identify the condition of the steering rack and front suspension bushings, which are wear-and-tear items.
After your drive, pop the bonnet and check for any sweet smells or residue around the coolant expansion tank. | Note: Cooling system connections in these models can occasionally weep over time, so it's a worthwhile visual inspection.
Consider replacing the spark plugs and performing a major fluid service including transmission fluid.
Monitor the condition of the serpentine belt and tensioner pulley.
General suspension refresh often becomes relevant here, focusing on control arm bushings.
Verify the service history specifically for oil changes every 10,000-15,000km.
Ensure the engine coolant has been inspected for proper concentration and leaks.
Check that the iDrive system has no pending 'Service Due' notifications.
Confirm the brake pads and rotors have sufficient material remaining.
Check the tire tread wear for signs of alignment issues, which are common on wider-rimmed setups.
Estimated repair costs if issues arise
While these are more reliable than older generations, they are plastic-based cooling components. If you notice a minor coolant weep in the future, it is best to replace the assembly to maintain engine health.
NZ roads can be quite varied, and these bushings often handle significant load. You might eventually need to budget for these if you notice extra road vibration or steering vagueness.
As the engine logs more kilometres, rubber gaskets can naturally harden. A small oil weep from the valve cover is a common consideration to address during a routine service interval.
