6.0L W12 TSI - Luxury SUV
Petrol
Check this by selecting 'Comfort' vs 'Sport' modes while stationary and moving. | Observation: Listen for any audible hissing or delay in the air suspension response; on these earlier models, the pneumatic struts can occasionally show signs of age.
While driving on a smooth surface, accelerate gently and listen to the gear transitions. | Observation: The 8-speed ZF transmission is generally robust, but any hesitation or 'clunking' between shifts suggests the transmission fluid may be due for a flush or the mechatronic unit warrants a diagnostic scan.
Check this by engaging the infotainment system and cycling through all menus repeatedly. | Observation: Electronics in high-spec luxury SUVs can be complex; ensure the screen doesn't flicker or lag, as these older modules are sensitive to battery voltage stability.
While at a stop with the engine running, feel for any vibrations through the steering wheel or seat. | Observation: The W12 is exceptionally smooth; if you notice excessive engine vibration, it may be worth checking the condition of the engine mounts, which can soften over time.
Consider a major fluid service including transmission and differential oils.
A common point to have the secondary ignition system and coil packs inspected for optimal W12 performance.
Typically the interval where suspension bushings and control arms are assessed for wear to maintain that Bentley ride quality.
Verify a consistent service history, ideally performed by a specialist who understands the unique requirements of the W12 powertrain.
Ensure the battery is healthy, as these vehicles rely heavily on stable voltage for their extensive electronic systems.
Check for any signs of weeping around the engine bay, as the W12 generates significant heat and rubber seals can become brittle with age.
Confirm the air-con system is performing well, as re-gassing and component repair in these luxury cabins can be quite labor-intensive.
Inspect the tyre condition across all four corners; ensure they are of a premium brand to match the vehicle's weight and performance requirements.
Estimated repair costs if issues arise
If this component needs attention in the future, it is a complex job involving the replacement of air struts or the compressor to restore the vehicle's poise.
Depending on the car's history, you might eventually need to budget for refreshing the cooling lines and hoses, as the intense heat of the W12 engine can fatigue cooling components over a decade.
If you find the brake sensors trigger a warning, know that the large rotors and pads required for this heavy SUV are bespoke items that carry a premium price tag.
