2016 Mercedes-Benz GLA 2.1L Diesel · KS66 AEF

The most recent MOT history for this 2016 Mercedes-Benz GLA demonstrates a stable roadworthiness trend, though the October 2025 failure—despite no recorded defects—raises questions about procedural irregularities rather than mechanical decline. The vehicle passed its final test on 22 October 2025, just two days after a failure at the same mileage (20,766), which suggests either a temporary administrative oversight or a test centre anomaly rather than a recurring mechanical issue. All prior tests from 2022 to 2024 were clean, with no advisories or defects noted, indicating no progressive wear patterns in suspension, brakes, or structural integrity during that period. The recorded mileage of 20,766 miles at the latest test reflects an exceptionally low annual average of approximately 2,077 miles over nearly a decade, which is atypical for a vehicle of this age. This suggests prolonged periods of inactivity, potentially indicating storage rather than active use. The mileage increments between tests are also unusually small—just 955 miles between the 2024 and 2023 tests, and 711 miles between 2023 and 2022—further supporting the likelihood of extended off-road storage. Such low mileage does not necessarily imply neglect, but it does warrant scrutiny of components prone to degradation from static conditions, such as tyres, suspension seals, and battery health. Given the lack of recorded defects in prior MOTs, a buyer should prioritise an in-person inspection of high-wear items that may not have been tested rigorously, such as suspension bushes and coil springs, which could degrade without obvious external signs. The October 2025 failure, despite no defects, hints at potential undetected issues in braking systems or emissions—particularly catalytic converter efficiency—so binding calipers, worn brake discs, or failing oxygen sensors should be checked. Additionally, the low mileage raises concerns about tyre condition; tread depth and lateral wear patterns must be verified, as prolonged storage can accelerate cracking or dry rot. Finally, corrosion at wheel arches, sills, and underbody should be inspected, as rust can develop even in low-mileage vehicles exposed to moisture or poor storage conditions.
