2001 Bentley Arnage 6.8L Petrol · MA51 RPX

The most recent MOT on 11 May 2026 was a pass, but it carried a series of advisories covering an oil leak, corrosion on both front and rear brake pipes, slight corrosion on the ferrules of all four brake hoses, front‑disc wear and a frayed off‑side front seat‑belt webbing. Over the last two years the same items have repeatedly appeared on both passes and fails, indicating a maintenance pattern that is essentially stable – the defects are not rapidly deteriorating, but they have not been fully resolved and continue to be flagged each test. The recurrence of brake‑related advisories suggests that the braking system is the principal area requiring attention before the vehicle can be considered fully reliable. With 43,603 mi recorded on a 2001 Bentley Arnage the average annual mileage works out at roughly 1,750 mi, which is considerably below the typical 8‑10 000 mi per year for a vehicle of this age. Such low utilisation often points to long periods of storage or very gentle use, which can be as much a concern as high mileage because components may suffer from age‑related degradation rather than wear from distance. Prolonged standing can promote corrosion of brake pipes, deterioration of rubber seals and hoses, and the perishing of tyre sidewalls, while the oil leak may be a sign of ageing gaskets or seals that have not been exercised regularly. A prospective buyer should give the brake system a thorough examination. Inspect the front brake hoses for any signs of external corrosion, cracking or stiffening at the ferrules, and verify that the hose ends are securely clamped without leaks. The front discs, flagged as pitted but not yet weakened, should be measured for thickness and checked for uneven scoring that could cause brake shudder or reduced stopping performance; any vibration or pulsation under hard braking would warrant immediate resurfacing or replacement. The corrosion noted on the front and rear brake pipes should be probed for rust or material loss, and the pipe joints examined for grease or debris that could impede fluid flow. The oil leak, although classified as non‑excessive, should be traced to its source – a valve cover gasket, oil filter housing or oil cooler – and repaired to prevent future engine oil loss or fire risk. Finally, the frayed off‑side front seat‑belt webbing must be replaced promptly to maintain occupant safety and comply with legal standards. Beyond the brake and oil concerns, age‑related checks are essential. Examine all four tyres for sidewall cracking, dry rot or loss of tread depth; even if the tread appears adequate, tyres older than six years can become brittle and should be considered for replacement. Test the 12 V battery’s voltage and cranking performance, as a vehicle that sits for long periods often develops a weak or sulfated battery. Verify that all fluid levels – engine oil, coolant, brake fluid and power‑steering fluid – have been changed within the manufacturer’s time intervals, as fluids degrade with age regardless of mileage. Inspect suspension bushings, ball joints and the rear sub‑frame for any signs of corrosion or looseness, and ensure the exhaust system is free of cracks or excessive rust, especially around the rear pipe that was previously noted as corroded. A comprehensive visual and tactile inspection, coupled with a careful road test listening for clunks, squeaks or unusual vibrations, will give a clear picture of whether the Arnage’s low‑mileage advantage outweighs the lingering maintenance items.
