2017 Renault Trafic 1.6L Diesel · SF17 CML

A pattern of recurring brake and underbody wear has emerged across this Trafic's recent MOT history, with the 2025 test cycle highlighting a cluster of advisories on both front and rear brake discs alongside a corroded, heavily greased brake pipe and a minor oil leak. The 2025-09-11 failure was unusual in that the same advisory items appeared on the subsequent pass a day later, suggesting the vehicle was likely presented with a known defect before being tidied and re-presented successfully. The disc pitting on both axles indicates the brake rotors are nearing the end of their service life and will likely require replacement at the next service interval, while the greased brake pipe is a cosmetic concealment of underlying corrosion that warrants close physical inspection. The oil leak advisory, although not flagged as excessive, is a recurring theme on high-mileage diesel commercial vehicles and should be traced to its source before it worsens. With advisories stacking up at the most recent test, the trend appears to be gradually worsening rather than improving, which is typical for a working van approaching its ninth year of service. The recorded mileage of 110,319 miles across nine years equates to an annual accumulation of roughly 12,258 miles, which is notably high for a private car but entirely consistent with the operational profile of a Renault Trafic typically used for commercial or fleet duties. There are no unusual gaps in the MOT history and the mileage progression between tests appears steady and proportionate, with no evidence of clocked readings or long stationary periods. This high but consistent usage means the mechanical wear profile should be expected to lean toward component fatigue rather than age-related degradation, particularly affecting the clutch, dual-mass flywheel, turbocharger, injectors, suspension bushes, and engine mounts. Buyers should interpret this mileage as an indicator that consumable and wear-item replacement is likely due imminently rather than something that can be deferred. From a buyer inspection standpoint, particular attention should be paid to the brake system given the documented advisories. On a test drive, listen for any grinding or pulsation through the pedal under firm braking, which would confirm the pitted discs have worn beyond a safe limit, and check that the vehicle pulls up straight without steering deviation. Inspect the visible brake pipes along the underside of the chassis and within the wheel arches for active corrosion or flaking, particularly where the grease coating may be masking the true condition of the metal. Verify that the handbrake holds the vehicle firmly on an incline, as rear brake issues on Trafics frequently manifest as binding or weak parking brake performance. An uneven or pulled steering response could also point toward worn track rod ends or front suspension components, building on the slight play advisory noted back in 2023. The oil leak flagged at the 2025 test should be investigated by inspecting the underside of the engine and gearbox for fresh drips or staining on the bellhousing, paying particular attention to the rocker cover gasket, turbo oil feed lines, and sump plug area which are common failure points on the 1.6 dCi unit. Cold-start behaviour should be observed for any excessive smoke, rattling from the timing chain area, or rough running that would suggest internal wear. With the nearside rear tyre already showing cracking and perishing, all four tyres should be checked for age-related sidewall deterioration regardless of tread depth, as commercial vehicles often accumulate UV and ozone damage. Finally, a thorough inspection of the suspension for knocking over speed bumps, wandering at motorway speeds, and uneven tyre wear across the axle would round out a proper evaluation, given that this Trafic's mileage and duty cycle demand a more rigorous assessment than a typical family car of the same age.
