2018 BMW 6 Series 2.0L Petrol · RO68 LFP

The most recent MOT test on 2025-09-08 resulted in a passing grade, though it highlighted persistent tyre-related advisories that have been recurring across multiple inspections. The pattern suggests a maintenance trend that, while not deteriorating acutely, requires vigilance—particularly regarding tyre wear and condition. The front tyres have shown consistent edge wear and sidewall perishing, indicating either underinflation, misalignment, or prolonged periods of low-speed use, which accelerates sidewall degradation. The rear tyres have also been flagged for wear near the legal limit, with some cracking, which may stem from uneven load distribution or excessive cornering forces. These advisories do not pose immediate road safety risks but underscore the need for proactive tyre management to prevent premature failure, especially given the vehicle’s age and the potential for further wear progression if not addressed. The recorded mileage of 34,618 miles for a vehicle aged eight years represents a notably low annual usage rate of approximately 4,327 miles per year, which is unusually low for a luxury sedan of this class. Such low mileage often correlates with extended periods of stationary use, particularly in urban environments where vehicles are frequently parked for days or weeks without driving. This can lead to several mechanical consequences, including accelerated corrosion in brake systems, particularly if the brakes are frequently applied without movement, causing heat-induced oxidation and potential binding of calipers or warping of discs. It may also contribute to fluid degradation in the brake, cooling, and power steering systems, as stagnant fluids can develop sludge or separation over time. Additionally, the suspension components, such as bushes and dampers, may exhibit signs of stiffness or premature wear due to reduced dynamic loading, though this is less critical than the standing-related issues in the drivetrain and braking systems. Given the recurring tyre advisories and the critical brake failure from the 2022 MOT, the buyer should prioritise a thorough inspection of the braking system. Immediate attention is required to replace the front brake pads, which were found to be below the legal minimum thickness of 1.5 mm. During this inspection, check for signs of brake disc warping, uneven wear patterns, or corrosion that could indicate underlying issues such as binding calipers or seized hydraulic components. Listen for abnormal brake pedal pulsation or vibration during deceleration, which may signal warped discs or internal brake failure. Additionally, verify that the brake fluid level is adequate and that there are no leaks from the master cylinder or caliper seals. Beyond brakes, the tyre advisories warrant a full visual and tactile assessment of all tyres, including checking for cracks, bulges, or uneven tread wear that could compromise handling and traction. Rotate the tyres if necessary to redistribute wear evenly, and consider replacing the front tyres sooner than expected if the edge wear and sidewall damage continue to progress. For the broader vehicle assessment, the buyer should conduct a systematic physical inspection focusing on areas prone to standing-related corrosion and fluid degradation. Start with the brake system, ensuring the discs and rotors are free from corrosion, binding, or excessive heat damage, and that the calipers are functioning smoothly without sticking. Inspect the wheel bearings for excessive play or grinding noises when turning, which could indicate early failure. Next, examine the suspension for signs of stiffness or excessive play in the control arms, struts, or bushes, though these may not be immediately critical given the low mileage but could develop issues over time. Check for fluid leaks around the power steering reservoir, radiator, and oil cap, as stagnant fluids can degrade over months without use. Pay particular attention to the battery terminals and the negative cable for corrosion, which is common in vehicles left stationary for prolonged periods. Finally, given the vehicle’s age, inspect the tyre sidewalls for signs of perishing or cracking, which can compromise structural integrity and lead to sudden blowouts. If the vehicle has been stored indoors, this risk is less severe, but if outdoors, ensure the tyres are stored in a cool, dry place to prevent premature deterioration. For fluid servicing, refer to the manufacturer’s recommendations for brake fluid replacement every two years, as well as coolant and power steering fluid, which should be replaced at specified intervals regardless of mileage.
