2021 Mercedes-Benz Sprinter 314 Progressive CDI 2.1L Diesel · PF70 AAO

A pattern of drive‑shaft CV boot deterioration combined with persistent tyre‑damage advisories dominates the vehicle’s MOT record; the 2026‑02‑19 test finally cleared the van after earlier failures that highlighted split CV boots on both front axles and a non‑functioning central rear stop lamp. The recent pass shows no outstanding defects, yet the history reveals that the same CV‑boot weakness re‑appeared within a twelve‑month window and that tyre surface degradation has been a recurring advisory for three separate tyres. At 62,143 mi the van averages roughly 12,400 mi per annum, a mileage level that exceeds typical commercial‑van usage for a five‑year‑old Sprinter. The relatively high annual accumulation accelerates wear on consumables such as brake pads, tyre tread, and suspension bushings, and it also increases the likelihood of heat‑related degradation of rubber components like CV boots. No significant gaps appear in the MOT chronology, indicating regular testing but also suggesting that the mileage has been accrued steadily rather than in short, intensive bursts. Prospective buyers should give the front drive‑shaft joints a thorough tactile and auditory inspection. Look for any grease seepage around the CV boot housings, feel for play when the steering wheel is rocked at low speed, and listen for a rhythmic knocking or whine that intensifies with engine revs—symptoms that would confirm residual boot failure or impending joint wear. The brake pads were flagged as thin in early 2025; verify pad thickness by measuring the remaining material (a minimum of 3 mm is required) and test for pedal judder or reduced braking efficiency during a short stop‑to‑stop run. Tyre condition warrants immediate attention: three separate tyres were noted as slightly damaged or cracking in successive tests, and a mismatch of rear tyre sizes was recorded in 2024. Inspect each tyre for sidewall cracks, tread separation, or bulges, and confirm that all four tyres are of the same specification and size. Verify the operation of the central rear stop lamp and all outline marker lamps, as previous failures indicate possible wiring or bulb issues that could re‑appear. A comprehensive visual and functional check of these items, coupled with a road‑test for any steering pull or vibration, will provide a realistic picture of the van’s current roadworthiness before purchase.
