2017 Mercedes-Benz C 2.1L Diesel · PA55 ETT

A clean and stable roadworthiness profile emerges across six consecutive MOT tests, with the most recent assessment on 30 October 2025 recording a pass and no defects or advisories. The previous test on 8 November 2024 was similarly clean, and the test before that on 15 November 2023 passed without comment. Across the entire recorded history, there are no failures, no advisory items related to corrosion, braking efficiency, emissions, or structural integrity, and no repeat advisories on the same component from one year to the next. The only advisory recorded on this Mercedes-Benz C-Class is a single instance of slight play in the nearside front suspension arm ball joint in November 2022, and a batch of four tyre-wear advisories in November 2020. This represents a broadly unremarkable and consistent test outcome trend rather than any developing mechanical concern. Usage over the vehicle's nine-year life has been moderate, with 74,482 recorded miles equating to an annual accumulation of roughly 8,276 miles. This places the car close to the average mileage expected for a 2017 registration, indicating regular rather than occasional use. There are no extended gaps between tests that would suggest long periods of standing, and the mileage progression between annual tests appears consistent with steady daily driving. From a mechanical perspective, this kind of usage pattern tends to keep consumables such as brake pads, discs, tyres, and fluids cycling through their service intervals normally, and it avoids the particular risks associated with either extreme low mileage, such as dried seals and seized components, or very high mileage, which accelerates wear on suspension, drivetrain, and clutch assemblies. The single suspension advisory worth specific attention is the November 2022 entry noting slight play in the nearside front camber arm ball joint. Although this was an advisory rather than a failure, and no further comment has been made on the component in the two subsequent tests, a buyer should inspect the front suspension thoroughly. On a test drive, listen for any knocking or clonking from the front end over uneven surfaces, speed bumps, or when turning into kerbs at low speed. Feel for vagueness or vibration through the steering wheel, and check for uneven front tyre wear, particularly on the inside shoulder of the nearside front tyre, which would be consistent with the camber geometry being affected by the joint. Slack should also be physically checked by hand with the wheels off the ground if possible, and the condition of the related control arms, bushes, and anti-roll bar drop links examined, as Mercedes-Benz W205 platform components of this age commonly show wear in conjunction with one another. The four tyre-wear advisories from November 2020 affected all four corners simultaneously, indicating the tyres reached the end of their useful life as a set rather than pointing to an alignment or suspension fault. On inspection, verify that the current tyres are a matched set of appropriate size and load rating, and check the sidewalls for any cracking or perishing given the vehicle's age. Beyond the specific historical advisories, a test drive should include firm progressive braking from higher speed to check for pulling, vibration, or a soft pedal, as the records give no insight into brake pad or disc condition. Listen for any timing chain or engine rattle on cold start, monitor the instrument cluster for any warning lights, and confirm the air conditioning system functions, as these are common failure points on W205 C-Class models that would not necessarily be captured in an MOT test.
