Petrol
While at a standstill in gear, observe the transmission for any hesitation or 'shudder' during initial acceleration. | Note: The ZF 6-speed transmission is a peach, but at this age, look for signs of fluid degradation which can cause gear hunting.
Ensure you drive over a variety of surfaces and listen for any knocking sounds coming from the wheel arches. | Note: The air suspension system is clever but complex; listen for any signs of the compressor working overtime or 'dropping' corners.
Park on a level surface, leave the engine running, and look for any unusual vibrations through the steering wheel or seat. | Note: A smooth V6 should feel refined; noticeable vibrations may suggest that the engine or transmission mounts are reaching the end of their service life.
Cycle through every single cabin button, particularly the infotainment touchscreen and the parking sensors. | Note: Electronic gremlins can be common in luxury cars of this era; ensure all creature comforts are fully operational before you commit.
Usually the time to check the air suspension bellows for integrity and the cooling system hoses for perishing.
A common interval to verify the health of the timing chain guides and ensure transmission fluid has been refreshed if documented in the history.
Check the service log for regular oil changes using high-quality synthetic oil.
Verify if the suspension compressor has been serviced or replaced, as this is a key component for long-term comfort.
Look for evidence of 'coolant flushes' to ensure the radiator and heater matrix are free of debris.
Test the electronic parking brake; it should engage and disengage crisply without protest.
Check for any dampness in the boot area, as rear light seals can sometimes allow moisture to track in over time.
Estimated repair costs if issues arise
These provide that lovely Jaguar ride, but they are wear-and-tear items. If the car 'sinks' after sitting for a few days, you might eventually need to budget for professional attention to the system.
If the transmission feels a bit lazy, a fluid and filter change can often restore that silky shifting. It is a prudent bit of future budget planning to keep this gearbox healthy for many more kilometers.
The X350’s handling relies on many rubber bushings. Depending on the roads the car has traveled, these can wear; budgeting for a suspension refresh can sharpen the steering back to factory-like precision.
