2015 Mercedes-Benz C 2.1L Diesel · WM07 LMM

The most recent MOT test for this 2015 Mercedes-Benz C was conducted on 2025-08-30 and passed without any recorded defects, marking a positive turnaround from the previous year’s advisory issues. While the vehicle’s MOT history shows a pattern of advisories related to rear brake components and tyre wear in 2023 and 2024, the absence of any failures or further advisories in the latest test suggests a stabilisation of the maintenance profile. The vehicle’s performance in the 2022 MOT and the clean 2023 test further reinforce that the issues from 2023–2024 were likely reactive to wear progression rather than systemic failures. However, the presence of persistent advisories—particularly on brake pad thickness and disc condition—indicates that the braking system remains under scrutiny and requires attention to prevent potential roadworthiness risks, such as reduced braking efficiency or premature disc failure. The recorded mileage of 103,492 miles for a vehicle aged approximately 11 years reflects a moderate annual usage rate of around 9,408 miles per year, which is consistent with typical driving patterns for this class of car. This level of mileage is neither exceptionally high nor low for a 11-year-old vehicle, though it does suggest a mix of operational and possibly prolonged stationary periods. Higher mileage in this context would typically accelerate wear on consumables like brake pads, tyres, and suspension components, while lower mileage could mask issues due to reduced dynamic loading. The 2023 MOT failure—particularly the dangerous nearside rear tyre failure—may have been exacerbated by either rapid mileage accumulation or prolonged standing, which can lead to uneven wear or premature tyre degradation. As such, the buyer should be cautious about any signs of irregular tyre wear patterns, such as excessive edge wear or central cupping, which could indicate misalignment or suspension issues. Given the advisories on rear brake pads and discs, the prospective buyer should conduct a thorough inspection of the braking system during the test drive. Listen for any unusual noises, such as squeaking or grinding, which could signal pad wear or disc warping. Inspect the rear brake discs for any signs of excessive pitting, scoring, or uneven thickness, and check for binding or excessive play in the calipers, which may indicate misalignment or seized components. Additionally, visually confirm that the brake pads are not significantly reduced in thickness beyond the advisory limits, as further wear could lead to a failure in the next MOT test. If the pads are already at the minimum safe thickness, consider replacing them promptly to avoid compromising braking performance. For the tyres, ensure that the remaining tread depth is well above the legal minimum and that there are no signs of uneven wear or bulges, which could indicate underlying suspension or alignment problems. Beyond the immediate concerns, the buyer should also address the broader roadworthiness and longevity of the vehicle. Given the age and mileage, inspect the tyres for signs of sidewall cracking or perishing, which can occur from prolonged exposure to UV light and age-related degradation. Check the vehicle’s standing condition for any signs of corrosion, particularly around the wheel arches, exhaust system, and undercarriage, as standing can accelerate rust formation. Verify the condition of the 12V battery and associated electrical systems, as older vehicles may experience reduced cranking power or starter issues due to battery degradation or loose connections. Finally, since the vehicle has not undergone a full service in the last 12 months, consider scheduling a comprehensive inspection to address fluid levels—particularly brake fluid, coolant, and transmission fluid—due to their susceptibility to degradation over time. If the service history is incomplete, ensure that all mandatory service intervals (e.g., timing belt replacement, suspension component checks) have been documented and performed, as these are critical for maintaining structural integrity and performance.
