2018 Volvo S90 2.0L Diesel · YY18 ROU

The most recent MOT test on the 2018 Volvo S90 occurred in December 2025 and resulted in a passing grade, though it did not eliminate the persistent tyre wear advisories observed across multiple previous inspections. The overall maintenance trend over the past five years shows a pattern of recurring tyre-related advisories—specifically, nearside and offside front and rear tyres worn close to the legal limit with edge wear—which suggest either aggressive driving habits, uneven load distribution, or a lack of regular wheel alignment or balancing. The failure in 2023 highlighted a critical issue with rear brake pads being dangerously thin, below the 1.5 mm minimum required for roadworthiness, indicating that the vehicle’s braking system has not been adequately serviced or replaced at the appropriate intervals. While the 2024 and 2025 tests did not record this failure, the presence of multiple advisories in the same category over consecutive years raises concerns about underlying wear patterns that may escalate if not addressed promptly. The recorded mileage of 83,297 miles for a vehicle aged eight years represents an average annual usage of approximately 10,412 miles, which is within the expected range for a car of this age and class. However, the consistency of the mileage data—without evident long periods of inactivity—implies either regular, moderate use or a driver who maintains a steady pace. The lack of significant mileage gaps does not necessarily indicate excessive wear, but it does mean that consumables like brake pads, tyres, and suspension components have accumulated wear over time rather than being replaced through routine maintenance. The tyre advisories, in particular, may reflect either underinflation, improper wheel alignment, or prolonged periods of static loading, all of which can accelerate uneven wear patterns. Given the recurring tyre wear advisories and the critical brake pad failure from 2023, the prospective buyer should prioritise a thorough inspection of the braking system, focusing on the rear calipers and discs for signs of binding, corrosion, or excessive heat damage. On a test drive, listen for uneven brake pedal response, shuddering or pulsation during braking, or a grinding noise that could indicate worn pads or warped discs. Additionally, check for fluid leaks around the brake master cylinder and calipers, as well as any excessive heat discolouration on the discs. The tyres should be inspected for signs of uneven wear beyond the advisories—such as cupping or directional wear—which could point to suspension or alignment issues. If the wear is confirmed to be within the legal limits but consistently close to the threshold, consider replacing the tyres sooner than expected to prevent further degradation and potential road hazards. Beyond the immediate concerns, the buyer should also address the broader maintenance history by verifying the service records for the brake system, suspension, and fluid servicing. The Volvo S90’s 2018 model year is particularly sensitive to fluid degradation over time, especially the brake fluid, which should be replaced every two years or 60,000 miles to prevent corrosion of the brake components. Inspect the brake fluid level and condition, checking for darkening or contamination, and ensure it has not been left exposed to moisture or heat. For the suspension, examine the coil springs, shock absorbers, and suspension bushes for signs of stiffness, cracks, or excessive play, which could indicate wear or failure. A visual check of the exhaust system for leaks or corrosion is also prudent, as the S90’s catalytic converters and mufflers may require attention as the vehicle ages. Finally, given the vehicle’s age and mileage, consider a thorough inspection of the engine bay for signs of oil leaks, coolant system integrity, and the condition of the 12V battery, which can degrade over time even with low usage. Pay particular attention to the battery terminals for corrosion, as standing corrosion can lead to poor electrical connections and potential electrical system failures.
