2014 Mercedes-Benz C 2.1L Diesel · IW 4529

The vehicle presents a complex maintenance history characterized by a significant mechanical failure in September 2025. During the test on 3 September at 47,002 miles, the Mercedes-Benz failed immediately due to multiple brake-related defects. The tester identified excessive corrosion on the offside front brake pipe and noted the nearside front brake pipe was obscured by grease or material. Additionally, the nearside rear brake pads were thin, and the braking system failed to meet efficiency requirements. While the vehicle passed a retest just eight days later on 11 September with no further defects recorded, the initial failure indicates a period where critical safety components were neglected until they reached a threshold. At 12 years old, this Mercedes-Benz C-Class has covered exceptionally low mileage, averaging approximately 3,900 miles per year. This low usage often leads to the degradation of rubber components and corrosion on metal brake lines rather than mechanical wear from distance. The May 2024 test at 44,362 miles showed both the nearside and offside front tyres approaching the legal tread limit, suggesting a pattern of reactive maintenance rather than proactive replacement. The gap between the 2023 and 2024 tests shows an increase of roughly 3,000 miles, consistent with the low-mileage profile of the vehicle. A buyer should prioritize a thorough inspection of the braking system to ensure the corrosion noted in 2025 has been properly addressed rather than merely cleaned. The presence of grease on the nearside front brake pipe previously suggests a potential attempt to hide leaks or corrosion from the tester. Given the low mileage, the condition of the suspension bushes and brake discs across all corners is vital, as low-use vehicles often suffer from uneven wear or seized components. The vehicle currently holds a valid MOT, but the September 2025 failure highlights a history of brake issues that were only rectified upon inspection.
