2020 Mercedes-Benz A 250 AMG Line Executive E A 1.3L Hybrid electric (clean) · SD70 AFU

A persistent pattern of front-axle brake and tyre defects dominates the MOT history of this 2020 A 250 AMG Line and forms the most important mechanical consideration for any prospective buyer. The most recent test on 11 August 2026 was a pass, but only after a fail on the same vehicle just four days earlier when the offside front tyre was found with ply or cords exposed on both inner and outer shoulder, a dangerous defect, alongside a major offside front service brake that was excessively binding. Because the binding caliper prevented the wheel bearing from being checked, the subsequent pass should be read with caution rather than as confirmation of full repair. The 2025 test cycle repeated the same story at the front axle, with both nearside and offside front tyres flagged as worn close to the legal limit on their edges, and the 2023 fail recorded an offside front tyre with ply or cords damaged on the outer sidewall together with a nearside front tyre devoid of tread. Across four of the six recorded test events, the front tyres have been the primary cause of concern, while the rear axle has produced its own set of brake disc and binding advisories in 2024. The recorded mileage of 66,806 miles across six years equates to an average accumulation of roughly 11,134 miles per year, which sits comfortably within typical parameters for a vehicle of this age and segment. The MOT history itself is densely recorded, with three calendar years (2023, 2025 and 2026) each showing paired test attempts, indicating either a deliberate policy of pre-test rectification or, more probably, vehicles being submitted while still presenting issues that required a re-test. There is no evidence of a prolonged off-road lay-up such as a multi-year gap in testing, so conclusions regarding standby deterioration of brake discs, callipers or tyre sidewalls through non-use cannot be drawn from the record. The mileage progression between tests is broadly consistent and does not show any anomalous jumps that might indicate clocking or unusual commercial use. For a buyer, the front brake and tyre package on this vehicle must be regarded as a known weak point. The offside front caliper was recorded as excessively binding on the August 2026 fail and the wheel bearing could not be inspected as a direct consequence, meaning that any subsequent purchase should include a raised-axle check to confirm the caliper has been properly overhauled or replaced, that the offside front wheel bearing is free of roughness or play, and that the brake disc run-out and remaining friction material thickness are within tolerance. The 2024 test additionally recorded both rear brake discs as worn, pitted or scored, with both rear service brakes showing slight binding, so a visual inspection of the rear caliper guide pins and a check for uneven pad wear is advisable. On a test drive, listen for a continuous rubbing or scraping noise from the front offside corner that does not stop with the pedal released, and feel for the vehicle pulling towards the right under braking or for a brake pedal that feels firm but produces inconsistent retardation. Tyres should be inspected on both shoulders of the offside front in particular, looking for any step or bulge in the sidewall, and the remaining tread depth measured across the full width rather than just the centre, because the recorded advisories specifically note edge wear on both front tyres in 2025. The remainder of the mechanical picture is comparatively low-risk but still warrants attention. Undertrays and sill covers have been flagged at the last two tests as obscuring underside components, meaning that items such as the front subframe, suspension arms, anti-roll bar links, brake pipes and the exhaust system could not be fully examined by the tester. A buyer should therefore arrange for these covers to be removed for a targeted inspection, paying particular attention to surface corrosion on the lower suspension arms and anti-roll bar bushes, any seepage from the front strut assemblies, and the condition of the flexible brake hoses where they pass through the wheel arch liners. The nearside rear child seat fitted during the 2025 test prevented inspection of the adult belt, so the rear belt retractors and anchorages should be physically checked. Finally, because hybrid emissions were not assessed in 2025, it is worth confirming that the petrol engine and 48-volt mild-hybrid system have been independently scanned for fault codes and that the auxiliary battery state of health has been verified, particularly as the vehicle is now six years old and approaching the typical service interval band for this powertrain.
