2019 Mercedes-Benz S-Class 2.9L Diesel · AB60 ADE

The most recent MOT test on 2026-04-09 resulted in a clean pass with no recorded defects, marking a positive continuation of the vehicle’s roadworthiness. Over the past seven years, the MOT history demonstrates a generally stable maintenance profile, with no failures or repeated severe issues. The advisories from previous tests—particularly the front brake pad and disc wear advisories—suggest routine wear that aligns with typical usage patterns rather than progressive or critical deterioration. The absence of failures in the last three MOTs indicates that while consumables like brakes and tyres are approaching their operational limits, the vehicle remains mechanically sound and compliant with current legal standards. The recorded mileage of 45,373 miles for a 2019 S-Class reflects a moderate annual usage rate of approximately 6,482 miles per year, which is consistent with its age and typical driving conditions. This level of mileage does not suggest excessive wear beyond what would be expected from regular use, though it does imply that the vehicle has accumulated significant wear on components like brakes, tyres, suspension, and drivetrain elements over time. The lack of substantial mileage gaps or rapid accumulation in recent years supports the notion that the vehicle has been maintained under reasonable conditions, though buyers should be mindful of potential hidden wear from prolonged idling or low-mileage standing, which can accelerate corrosion in brake systems, suspension components, and fluid degradation. Given the advisories recorded in the last two MOTs—front brake pads and discs approaching their operational thresholds—buyers should conduct a thorough inspection of the braking system during the purchase process. Look for uneven wear patterns on the brake discs, which could indicate misalignment, warping, or binding calipers that may require adjustment or replacement. Listen for any grinding noises during braking, which may signal metal-to-metal contact between pads and discs, and check for pulsations or vibrations that could suggest warped discs or worn suspension components. Additionally, verify that the brake fluid level is within specification and that there are no leaks around the brake master cylinder or calipers. Impending maintenance for the front brake system should be scheduled within the next 1,000 to 1,500 miles to replace pads and discs before they reach critical wear limits, which could compromise stopping performance and safety. For the tyres, the advisories from the 2024 MOT—both front tyres worn close to the legal limit with edge wear—highlight the need for a closer inspection of tread depth and tread pattern integrity. Edge wear often results from underinflation, misalignment, or excessive camber angles, all of which can accelerate tyre degradation. Measure the tread depth across multiple locations on the tyre to confirm whether they are at or near the legal minimum of 1.6mm, as further wear could lead to hydroplaning risks in wet conditions. Inspect the tyre sidewalls for signs of cracking, perishing, or dry rot, which can weaken the tyre structure and compromise safety, particularly in older vehicles exposed to UV degradation over time. If the tyres are approaching their service life, consider replacing them to prevent blowouts or sudden failures, especially given the vehicle’s age and the potential for hidden internal damage from prolonged use. Beyond the immediate checks, buyers should also verify the condition of the suspension, including coil springs, shock absorbers, and suspension bushes, as wear in these areas can lead to poor handling, uneven tyre wear, and increased risk of accidents. Finally, address the potential for standing corrosion in the brake system, as prolonged idling can cause rust buildup in brake lines, calipers, or wheel bearings, which may require professional inspection and flushing to prevent future failures.
