Our Verdict
Proceed with caution and budget for imme
When inspecting this specific A-Class, your priority should be verifying the resolution of the 2024 airbag failure. An inoperative passenger airbag is a significant safety concern; ensure there is documented proof that the fault was rectified and that the airbag warning light is not present on the dashboard.
Given the 2025 failure regarding the nearside rear coil spring and front brake discs, check the suspension for any remaining knocks or rattles and inspect the braking system thoroughly. Because this is a 1.5L diesel engine with nearly 100,000 miles, ask for evidence of regular oil changes and check for any signs of DPF (Diesel Particulate Filter) issues, which are common in high-mileage diesel engines.
The 1461cc diesel engine is generally designed for efficiency, which should help keep fuel costs manageable for long-distance driving. However, at nearly 100,000 miles, maintenance costs for wear-and-tear items like brakes, suspension components, and tyres are likely to increase.
Insurance groups for the A-Class vary, but you should obtain a specific quote based on the registration T100AAR. Expect annual running costs to be moderate, primarily driven by fuel consumption and the necessity of servicing high-mileage diesel components.
Specifically address the recent MOT failures: inspect the front brake discs for any signs of remaining pitting or scoring, and check the rear suspension components to ensure the fractured coil spring issue has been fully resolved.
Crucially, test all exterior lighting, including the offside stop lamp and rear position lamps, as these were noted as failures in 2024. Finally, perform a thorough check of the interior electronics and airbag warning lights to ensure the safety system is fully operational following the previous failure.
This 2015 black Mercedes-Benz A-Class diesel has covered 99,875 miles, which is significantly higher than the model average of 7,310 miles per year. The MOT history shows a pattern of failures, including a notable 2024 failure involving an inoperative passenger airbag and lighting issues, followed by a 2025 failure regarding brake discs and a fractured coil spring. The vehicle's high mileage and history of component failures suggest it has been used heavily.
Aggregate data from over 260,000 vehicles shows an 82% MOT pass rate for this model, with common failures typically relating to tyres, wipers, and headlamps.

Historical MOT pass rates and DVLA records for 2015 model year cars.
- OM651 Diesel Chain Tensioner Oil LeakModerate
On 1.8-litre and 2.1-litre OM651 diesel engines, the timing chain tensioner seal is a well-documented weak point. Over time the rubber O-ring gasket degrades, leading to persistent engine oil weeping down the right flank of the engine block. Left unaddressed, loss of oil pressure at the tensioner can cause timing chain rattle on startup and premature stretch.
- DCT gearbox judder and clutch wearModerate
The 7G-DCT dual-clutch transmission (Getrag/Mercedes 724.0) suffers from low-speed lurching, clutch shudder, and software calibration drift, particularly on cars driven primarily in stop-start urban traffic. Neglecting the mandatory 4-year/40,000-mile transmission fluid and dual-filter service accelerates clutch pack wear and mechatronic solenoid sticking.
- M270 Petrol Timing Chain StretchSerious
The 1.6-litre and 2.0-litre M270 turbocharged four-cylinder petrol engines can experience timing chain elongation and tensioner fatigue, especially when subject to extended variable service intervals. An elongated chain causes camshaft timing deviation, triggering check engine warnings and in severe cases skipping teeth.
