2020 Mercedes-Benz GLC 300 AMG Line 4MATIC Auto 2.0L Hybrid electric (clean) · DF70 ADU

The vehicle is currently roadworthy, having passed its latest MOT in December 2025 at 58,266 miles with no defects recorded. However, the maintenance trend shows a period of instability during late 2024. While the 2023 test at 45,165 miles was clean, the failure in December 2024 indicates a lapse in oversight regarding critical electronic and safety systems that required immediate rectification before the subsequent pass. The mileage pattern is consistent with a six-year-old vehicle, averaging approximately 10,000 miles per year. The car covered 12,947 miles between the December 2023 and December 2024 tests, suggesting a higher rate of use during that period. The interval of only 154 miles between the December 2024 failure and the December 2025 pass indicates that the faults were addressed quickly, or that the vehicle was submitted for a retest shortly after the repairs. A buyer must prioritise a thorough inspection of the braking and electronic systems based on the 2024 failures. The inoperative engine Malfunction Indicator Lamp and brake pad warning lamp suggest that sensor faults or wiring issues were previously present. You should verify that no fault codes remain in the engine management and ensure the sensors were replaced rather than merely reset. Additionally, the offside front tyre failure in 2024 warrants a check of the remaining tread depth and condition across all tyres to ensure consistent wear and proper alignment.
