2016 Mercedes-Benz CLA 2.0L Petrol · AM15 ART

A clean MOT history on paper, but the two failures without recorded defects deserve scrutiny. The 2016 Mercedes-Benz CLA passed its most recent test on 19 May 2025 with no advisories, and its earlier passes in 2024 and 2023 are similarly clean. However, both recorded failures, on 15 May 2025 and 24 March 2023, show no defect entries, which typically means items were identified but not categorised as failable, or the test was aborted for administrative reasons. The timing of the 2025 pass coming just four days after the failure suggests a quick rectification and re-test, a pattern consistent with a minor issue that was resolved before the retest. Mechanically, the absence of any recurring advisories across five tests indicates no chronic wear issues have been flagged by DVSA examiners, though the lack of advisory detail across all tests is somewhat unusual for a vehicle approaching a decade of age. At 59,442 miles over ten years, this CLA has averaged roughly 5,944 miles annually, which is notably below the typical 7,000 to 10,000 miles per year expected for a daily-driven vehicle. This low accumulation suggests either a secondary vehicle role, predominantly short urban trips, or extended periods of inactivity. Such low mileage brings specific mechanical considerations: the 2.0-litre diesel or petrol engine, depending on variant, will have experienced limited thermal cycling stress on gaskets, seals, and turbo components, but prolonged standing can accelerate ageing of rubber components, brake caliper slide pins, and underbody corrosion through moisture entrapment. The relatively consistent annual test intervals with no multi-year gaps suggest the vehicle has been kept on the road throughout its life rather than stored and re-registered. For a prospective buyer, the absence of component-specific advisories means there is no DVSA-documented pattern of wear to investigate, which is reassuring but not definitive. Given the low mileage, particular attention should be paid during inspection to the condition of rubber suspension bushes, anti-roll bar drop links, and the front lower wishbone components, which can perish from lack of use rather than wear. On a test drive, listen for clonking or knocking from the front suspension over speed bumps and uneven surfaces, as seized or perished bushes and ball joints may not be evident at low speed. Check for any pulling under braking or uneven brake pedal feel, which can indicate seized caliper pistons or corroded slide pins from infrequent use. Also worth investigating is the exhaust system, particularly the rear silencer and mounting rubbers, which are prone to internal corrosion on low-mileage vehicles that complete many short journeys. Inspect the underside for any surface corrosion on subframe and suspension arms, and examine the engine bay for any oil misting or dampness around the cam cover, oil filter housing, and turbocharger, as Mercedes-Benz M270 and OM651 engines are known for such seepage. Finally, verify that all electronic systems function correctly, including the infotainment display, parking sensors, and any optional equipment fitted to this premium trim, and confirm the service history substantiates the mileage with documented intervals appropriate to the engine type.
