2018 Bentley Mulsanne 6.8L Petrol · D2 HYD

The most recent MOT test on the Bentley Mulsanne, conducted on 2026-05-18, resulted in a clean pass with no recorded defects, marking a positive turnaround following two consecutive failures related to brake pad thickness. While the vehicle’s maintenance history shows a pattern of recurring brake-related issues—particularly in 2023 and 2025—this latest test suggests either effective remedial work or a shift in wear patterns, though the prior failures indicate persistent friction system challenges. The overall trend remains mixed; while the vehicle has avoided dangerous failures in recent years, the brake advisories and wear indicators highlight a need for proactive attention rather than a stable, low-risk maintenance profile. The fact that the Mulsanne passed the 2026 test without major defects does not absolve the buyer of due diligence, especially given the vehicle’s age and the history of brake-related MOT failures. The recorded mileage of 29,039 miles for a vehicle aged approximately eight years is notably low, reflecting an annual usage rate of around 3,630 miles—far below the typical expectations for a luxury car of this class. Such low mileage can stem from either light operational use or prolonged periods of stationary storage, both of which introduce distinct mechanical considerations. If the vehicle has spent significant time stationary, particularly in a damp or corrosive environment, this could accelerate wear on components like brake discs, calipers, and suspension elements, which may have shown signs of degradation despite the low mileage. Conversely, if the mileage is genuinely low due to regular use, the wear on consumables such as brake pads, tyres, and fluids may be more conservative, but the risk of hidden issues—such as internal brake pad contamination, caliper binding, or fluid degradation from infrequent servicing—remains elevated. Given the vehicle’s history of brake-related MOT failures, the prospective buyer should conduct a thorough inspection of the friction system, focusing on the front and rear brake pads, discs, and calipers. Visually inspect the brake pads for even wear and signs of glazing or contamination, which can indicate poor braking performance or premature failure. Listen for any unusual noises during a test drive, such as grinding when braking, which could signal worn pads or damaged discs. Check for uneven tyre wear patterns, which may point to misalignment or binding calipers. Additionally, examine the brake fluid reservoir for contamination or bubbles, as this could signal a failing master cylinder or brake booster. If the brake system has not been serviced recently, consider a professional inspection to assess the condition of the hydraulic system and ensure there are no hidden leaks or corrosion. For the broader vehicle condition, given the low mileage and age, the buyer should prioritise checks on the tyre sidewall for signs of perishing or cracking, which can compromise structural integrity and safety. Inspect the 12-volt battery for corrosion around terminals and ensure it holds a charge when static, as standing vehicles can lead to battery drain and related electrical system issues. Pay attention to the suspension for any signs of excessive play, clunking noises, or worn suspension bushes, which may indicate long-term standing-related wear. Fluid levels, particularly the engine oil, coolant, and brake fluid, should be checked for freshness and contamination, as fluids degrade over time even with low mileage. Finally, verify that the service book or maintenance records are up to date, particularly for time-based servicing such as the timing belt (if applicable) and fluid replacements, to ensure the vehicle remains in optimal condition for its age and usage profile.
