2010 Mercedes-Benz C 2.1L Diesel · AE10 OBD

The vehicle's current roadworthiness status is uncertain, as its most recent MOT certificate expired over two years ago in June 2024. The maintenance trend appears stable based on the record, with the car ultimately passing its tests, yet a peculiar anomaly exists. The tester recorded zero defects for both the failed and passed tests in 2023 and 2024. Failing an MOT without any logged defects typically indicates an aborted test, possibly due to dense exhaust smoke preventing an emissions reading or a dangerous component halting the inspection before a full assessment could be completed. The mileage accumulation tells a distinct story of recent inactivity. Between May 2022 and June 2024, the car covered roughly 25,789 miles, averaging about 12,000 miles per year, which aligns with typical use for a 2010 Mercedes C-Class. However, the odometer has remained entirely stationary at 123,514 miles since the June 2024 pass. This indicates the vehicle has stood idle for over two years. Prolonged standing causes its own mechanical issues, including seized brake calipers, perished rubber suspension bushes, and degraded tyres, regardless of the clean MOT record. A buyer must approach this vehicle with caution due to its extended dormancy. A thorough in-person inspection should focus on the braking system, specifically checking for binding calipers and corrosion on the brake discs caused by inactivity. The condition of the tyres requires close scrutiny for flat spots and sidewall cracking from remaining stationary under load. Suspension components, particularly the bushes and coil springs, need examination for deterioration. Given the unexplained fails with zero defects, verifying the engine's condition and exhaust emissions output is critical to ensure the powertrain runs cleanly and does not suffer from the issues that likely aborted the previous tests.
