2012 Mercedes-Benz CLS 3.0L Diesel · YF12 RXH

The current MOT status of this Mercedes-Benz CLS is technically valid until January 2026, meaning the vehicle is now operating outside of its certified test window as of July 2026. The maintenance trend appears stable regarding major mechanical failure, as the car has achieved consecutive passes since the 2022 failure. However, the recurring advisories for tyre wear and the persistent engine oil leak noted in early 2024 suggest that while the vehicle remains functional, it is being maintained on a reactive basis rather than through proactive servicing. The recorded mileage of 162,135 over fourteen years averages to approximately 11,600 miles annually, which is consistent with typical usage for a luxury saloon of this class. The jump of nearly 20,000 miles between the January 2024 test and the January 2025 test indicates a period of heavy motorway use. The lack of test data between 2022 and 2024 suggests the vehicle may have been off the road or subject to a different registration cycle, but the current accumulation rate confirms the drivetrain is being pushed significantly in its later life. Prospective buyers must prioritise a thorough inspection of the front suspension and steering geometry. The history of uneven tyre wear, combined with previous advisories for wheel bearing play and suspension arm bushes, indicates that the front end is prone to rapid component degradation. You should also verify the extent of the oil leak identified in 2024, as this can often mask deteriorating gaskets or seals that are costly to rectify on this engine platform. Finally, inspect the subframe mounting points for any signs of worsening corrosion, as the 2022 test flagged these areas as a concern before they reached the threshold for a formal failure.
