2017 Mercedes-Benz Vito 1.6L Diesel · HT17 NNV

The most recent MOT test on 2026-01-23 resulted in a clean pass, marking a positive turnaround after two consecutive failures in 2022 and 2023. While the vehicle’s MOT history shows a pattern of recurring issues—particularly engine-related faults and lighting defects—these failures have now been resolved, suggesting that the underlying problems have either been addressed or are no longer active. The absence of further defects in the last three years indicates a stable maintenance trend, though the prior failures highlight areas where the vehicle’s reliability may have been compromised. The fact that the latest test passed without advisories or major issues is encouraging, but prospective buyers should remain vigilant about the historical patterns, especially regarding the engine control unit (ECU) and brake system, as these were persistent failure points. The 2017 Mercedes-Benz Vito’s recorded mileage of 99,441 miles over approximately nine years represents an average annual mileage of around 11,049 miles, which is within the expected range for its age and class. This usage rate suggests moderate to heavy operational demands, particularly if the vehicle has been used for commercial or high-mileage purposes, such as fleet operations or long-distance travel. However, the absence of significant mileage gaps—such as those indicative of prolonged idling or infrequent use—does not necessarily mean the vehicle has been driven excessively; it could reflect consistent, albeit moderate, usage patterns. Regardless, higher mileage increases the likelihood of wear on critical components like suspension bushes, brake pads, drivetrain seals, and fluid-degrading elements such as transmission fluid or engine oil, so a thorough inspection of these areas is prudent. Given the vehicle’s MOT history, the buyer should prioritise a comprehensive mechanical inspection to address the historical defects and prevent recurrence. The engine MIL (Malfunction Indicator Light) failures in 2022 and 2023 suggest persistent issues with the ECU or related wiring, which may have been resolved but could reappear if not properly serviced. During a test drive, listen for irregular engine noises, such as knocking or hesitation, which could indicate deeper engine or transmission problems. The brake system failures in 2022—particularly the loose, split brake pedal and worn clutch rubber—demand immediate attention. Inspect the brake discs and pads for uneven wear, corrosion, or binding calipers, and check for a spongy or uneven brake pedal feel, which may signal hydraulic issues or worn brake lines. Additionally, the nearside and offside headlamp aim failures suggest misalignment, which could be corrected by recalibrating the headlight assembly, but verify that the internal headlight adjusters have been properly restored to factory settings. For practical checks beyond the MOT, the buyer should focus on the vehicle’s age and mileage-related wear. Given the Vito’s age and mileage, inspect the tyres for signs of sidewall cracking or perishing, which can weaken the structure over time, even if the tread remains legal. Check the tyre pressure and tread depth regularly, as the tyre pressure monitoring system (TPMS) failure in 2023 indicates a potential sensor or wiring issue that may recur. The battery should be tested for voltage and corrosion, especially if the vehicle has been stored or driven infrequently, as standing corrosion or a failing 12V battery can lead to electrical gremlins or starting difficulties. Fluid levels, including coolant, brake fluid, and transmission fluid, should be checked for contamination or degradation, as these fluids degrade over time regardless of mileage. Finally, verify that the service book or maintenance records have been updated, particularly for the engine oil change intervals and suspension component replacements, as the Vito’s suspension may have experienced wear due to the high mileage. If the vehicle has been driven consistently, the suspension bushes and coil springs should be inspected for excessive play or cracking, and any clunking noises during cornering or over bumps should be noted.
