2023 Volkswagen Transporter T28 Highline TDI 2.0L Diesel · GD23 NHY

A late-2023 Volkswagen Transporter T28 Highline TDI with around 29,000 miles on the odometer presents an unusually thin MOT history, with only a single test recorded in July 2026 — its first mandatory inspection at three years of age. The defining mechanical note from the record is a same-day failure recorded on 13 July 2026 for the Engine MIL (Malfunction Indicator Lamp) being inoperative or indicating a malfunction under section 8.2.2.2 (g), which on a diesel of this type means the OBD / emissions readiness system flagged a fault that the dashboard warning lamp either did not illuminate for or was not properly functional when the tester checked it. The vehicle subsequently passed an MOT on the same date with no advisories, indicating the MIL-related issue was rectified prior to re-presentation, but the fact that an engine management or emissions-monitoring fault was present at the test at all warrants attention from any prospective buyer. Against the three-year age of the vehicle, the recorded mileage of 28,953 miles equates to approximately 9,651 miles per year, which is broadly typical for a commercial-derived Transporter but is on the lighter side of average for this class of vehicle. Because the van has only been MOT-tested once, there is no mileage progression data to confirm consistent use or to flag any sudden jumps; the gap between first registration and first test is normal given the three-year exemption from MOT testing applicable to vehicles first registered from 2012 onwards. Diesel T28 vans used at this rate of accumulation tend to see steady wear on DMF (dual-mass flywheel) and clutch components, turbo seals, EGR valves, DPF (diesel particulate filter) regeneration behaviour, and suspension bushes, but the MOT record itself does not contain any advisories or component-level defect data that would independently confirm or contradict any of these. Given the MIL failure, the priority during a pre-purchase inspection should be a thorough scan of the engine management system for stored DTCs (diagnostic trouble codes), particularly any historical or pending codes relating to the DPF, EGR, turbocharger, NOx sensors, or fuel injection system, as these are common causes of an MIL illumination on a 2.0-litre TDI. Ask the seller to see evidence of the rectification work carried out between the failure and the pass on the same day — invoices, diagnostic printouts, or component receipts — and confirm whether any software updates or recalls were applied, as VW issued several emissions-related actions for this generation of Transporter. On a road test, pay particular attention to the presence of any restricted power, uneven idle, excessive smoke from the exhaust during DPF regeneration cycles, or the management lamp re-illuminating shortly after being cleared, as these would suggest the underlying cause was not fully resolved. Beyond the engine management concern, the absence of any recorded advisories means there is no MOT evidence of wear patterns relating to braking components, suspension linkages, or corrosion at this point, but a physical check remains essential for a working van. On a test drive, listen for clonks or knocks from the front suspension over uneven surfaces, check for uneven tyre wear that could indicate alignment or worn suspension bushes, and feel for any pulling under braking or a soft brake pedal that could indicate binding calipers or perished brake lines, particularly given the heavier kerb weight of the T28 platform. Inspect the underside of the vehicle, paying close attention to the rear axle, spring seats, and jacking points for early corrosion, and verify that the underbody is free from oil misting or diesel staining around the engine, turbo, and injector area. Given the clean advisory record and modest mileage, this Transporter appears to be at an early stage of its service life mechanically, but the engine management history means confirmation of a clean and stable diagnostic state should be a condition of any purchase.
