2012 Mercedes-Benz C 2.1L Diesel · LS62 TZB

The most recent DVSA test outcome recorded on 12 May 2026 shows a failure, with the vehicle subsequently passing later the same day once rectification work was evidently carried out. The advisory regarding rear subframe corrosion above the rear differential is present on both the pass and fail entries of that date, suggesting it was noted but did not constitute an immediate failure. However, looking at the broader picture across the available MOT history, the maintenance trend cannot reasonably be described as stable. Recurring major defects have appeared on the front suspension across multiple tests in 2024, 2025, and 2026, specifically affecting ball joints on both nearside and offside lower arms and camber arms, which indicates progressive wear of the front suspension assembly rather than isolated incidents. Combined with the dangerous failures for tyre tread and rear brake pad condition in 2025 and brake pipe deterioration in 2024, the pattern reflects a vehicle whose consumable and chassis components are being driven hard and replaced reactively rather than preventatively. With 171,028 miles recorded against a 2012 registration, this C-Class has covered approximately 12,216 miles annually, which is a notably high usage rate for a passenger car of this age. Such consistent, high-mileage running accelerates wear on engine internals, transmission mounts, turbocharger components where applicable, suspension bushes and bearings, brake discs and calipers, clutch or torque converter components, and drivetrain flexible joints. The MOT history shows no significant gaps in testing, implying continuous use rather than periods of standing, which generally reduces the risk of seized calipers or severe underbody corrosion from inactivity but conversely increases the likelihood of component fatigue. It would be prudent to verify whether the engine, automatic or manual gearbox, and differential have been serviced in line with Mercedes-Benz intervals, particularly regarding automatic transmission fluid and filter changes, as high mileage on neglected fluid can lead to harsh shifting or mechatronic faults. Prospective buyers should pay particular attention to the front suspension during any inspection, as the MOT history records ball joint failures on multiple occasions spanning both sides and both lower and camber arms. On a test drive, listen for clonks or knocks from the front end over speed humps, uneven road surfaces, and during full-lock manoeuvres, as these are typical symptoms of worn ball joints and bushes. It would also be sensible to jack the vehicle and check for play in the wheels by hand, and to inspect the rear subframe for the corrosion flagged as an advisory in 2026, as corrosion in this area can progress and potentially affect structural integrity if left unchecked. The 2024 entry also identified a brake pipe corroded along the nearside rear sill and wheel arch, which is a structural area; ensure any replacement pipework has been properly routed and clipped, and inspect both inner and outer sills for evidence of repair or further corrosion. Given the high mileage and the chassis-related failures recorded, a thorough inspection of the braking system is essential. Check the rear brake calipers for the binding tendency noted in 2025, which can cause uneven pad wear, hot spots on the discs, and pulling under braking, and verify that the discs themselves have not worn below minimum thickness. The brake fluid should be assessed for age, as Mercedes-Benz typically specifies replacement every two years regardless of mileage, and old fluid significantly increases the risk of vapour lock under heavy braking. The tyres should be examined closely for any uneven shoulder wear, as the dangerous failure in 2025 for a bald outer edge with cracks and splits suggests possible camber or tracking issues, which may or may not have been resolved by the suspension work. Finally, confirm the timing chain or belt service interval status, inspect the condition of the coolant, power steering, and engine oil, and ensure the 12V battery is holding charge, as these age- and mileage-related items are not covered by MOT testing but are critical to the reliable operation of a high-mileage executive saloon.
