2017 Mercedes-Benz C 2.1L Diesel · CA02 EVA

This Mercedes-Benz C-Class presents a roadworthiness profile that is largely stable on test but is anchored by a single dangerous tyre depth failure and a cluster of advisories that warrant close attention. The most recent examination on 10 January 2026 was recorded as a pass with no defects, following an equally clean pass in February 2025, which together suggest that the core safety systems were performing within legal limits at the last two tests. However, the earlier failure on 28 November 2023 for a nearside rear tread depth below 1.6mm is a serious marker, classified as dangerous at the time, and it sits in the same window as a minor inoperative registration plate lamp that also appeared as an advisory on the subsequent pass in December 2023. Earlier still, the November 2022 pass carried three advisories relating to both front tyres being worn on edge and the front brake discs showing pitting and scoring. Taken together, the pattern points to a vehicle that has passed its tests but with a recurring theme of front-end wear and at least one episode of component condition falling well below the legal minimum. Recorded mileage of 144,789 miles over a nine-year lifespan equates to an average of roughly 16,000 miles per year, which is at the higher end of usage for a vehicle of this age. There is also a notable gap in the test record between February 2025 and January 2026, which may reflect either a late application or a period off the road, while the earlier gap from late 2023 through 2024 is consistent with normal annual testing. From a mechanical standpoint, this level of annual accumulation places sustained demand on the braking system, suspension components, tyres, clutch or automatic transmission fluid, and drivetrain mounts, all of which typically accumulate wear roughly in line with distance covered rather than calendar age. The front tyre edge wear and brake disc scoring recorded in 2022 are consistent with the kind of wear pattern one would expect at this mileage band, particularly if the vehicle has seen a high proportion of urban or corner-loaded driving. For a prospective buyer, the most relevant component to inspect is the front brake and suspension package, given that the only meaningful advisories in the record relate to front tyre wear and front brake disc condition. On a test drive, listen for any groan, vibration, or pulsing through the brake pedal that might indicate the discs have continued to wear or have developed run-out since the 2022 advisory, and feel for steering pull or uneven stopping that could suggest caliper binding or uneven pad transfer. Inspect both front tyres closely for inner-edge wear, as the 2022 advisory specifically noted wear on edge, which can be symptomatic of incorrect camber, worn suspension bushes, or weak top mount bearings rather than simply tyre age. The rear axle should also be examined for any signs of corrosion on spring seats, trailing arms, and brake pipe runs, particularly given the high annual mileage. Finally, the dangerous tyre failure from November 2023 should inform how the vehicle is checked over now. Tyres that have been replaced since that test should be inspected for correct size and matching specification on the same axle, and all four corners should be measured with a tread depth gauge rather than relied upon visually, as the 2023 nearside rear had dropped below the legal 1.6mm threshold. Under-bonnet, look for any signs of oil misting or weeping from the cam chain cover and turbo oil pipes, which are known areas on this generation of Mercedes-Benz, and check the condition of the auxiliary belt and pulleys given the mileage. On the road, pay attention to any clonks from the front suspension over uneven surfaces, as worn lower control arm bushes and anti-roll bar drop links are common at this odometer reading, and verify that the gear selection on the automatic transmission is smooth and free of delay, which would otherwise point toward internal wear within the gearbox.
