2004 Volkswagen Transporter 2.5L Diesel · HD04 CSX

A 22-year-old T4-generation Transporter carrying 120,772 miles presents a notably sparse and inconsistent MOT history, with the recorded test entries offering very little granular detail about its mechanical condition. The most recent test on 8 April 2026 was a clean pass with no advisories or defects recorded, and the prior pass on 2 April 2025 was similarly clean. However, the intervening entries are puzzling: the vehicle was failed on 26 March 2026 and on 2 April 2025, both with no defects recorded against the test. This pattern of immediately retested failures on the same day as a pass strongly suggests these were refusals to issue a certificate due to administrative issues, such as the absence of a current insurance or registration document, rather than genuine mechanical defects identified on inspection. The overall trend is therefore difficult to characterise mechanically, as no component-level advisories or failures have ever been logged, leaving the assessment reliant almost entirely on physical inspection rather than historical data. The recorded mileage of 120,772 miles across approximately 22 years equates to an annual accumulation of around 5,490 miles, which is low for a working van of this type. Commercial Transporter T4s typically cover substantially higher mileages, so this figure suggests the vehicle has either had a quieter life as a private or leisure vehicle, or has spent significant periods off the road between uses. There is no mileage recorded on the 2024 or 2025 test entries, which prevents verification of consistency in the usage pattern, and the absence of any recorded mileage progression means a buyer cannot confirm whether the van has been used steadily or has had long stationary periods. Lower mileage Transporter T4s are not necessarily mechanically superior; long periods of standing can be particularly hard on these vehicles, drying out cylinder bores, causing oil seals to harden, allowing fuel system seals to perish, and accelerating corrosion in the sills, jacking points, and underbody seams. Equally, the original 2.5-litre TDI engine, if it is the diesel variant, is known for cylinder head issues, so the combination of low mileage and the engine type warrants careful scrutiny. For a prospective buyer, the lack of any advisory history means there is no specific component wear data to act upon, making a thorough physical inspection essential. On a test drive, listen carefully for any signs of rough running or excessive smoke from the exhaust, particularly on the 2.5 TDI engine where injector wear and intermediate shaft issues are well-documented concerns. Check for knocks or clonks from the front suspension over speed humps and uneven surfaces, paying particular attention to the anti-roll bar drop links, which are a known weakness on T4s. The steering should feel precise without excessive play, and any clonking when turning at low speed can indicate worn steering rack mounts or track rod ends. Inspect the underside thoroughly for corrosion on the jacking points, chassis rails, and outriggers, as these areas are critical to structural integrity and are common failure points for MOT presentation. Given the low annual mileage, the brake system may also show signs of corrosion on the discs rather than wear from use, so a thorough check of the brake components and fluid condition is advisable, alongside verification that the cam belt or timing belt has been replaced at the correct interval for the engine fitted. The two immediately retested failures with no defects recorded do not indicate a mechanical problem, but a buyer should still request the VT30 refusal documents from the seller to confirm the administrative nature of those refusals. It is also worth confirming the engine type, as the 2.5 TDI diesel and the 2.0 petrol have very different maintenance profiles, and the timing belt or cam belt replacement schedule should be verified through service history. Given the vehicle's age, a compression test on a diesel engine or a leak-down test would be prudent, and the condition of the cooling system, including the radiator, water pump, and thermostat housing, should be inspected for signs of perished plastic or slow leaks. Finally, check the operation of the sliding side door and tailgate, as the mechanisms and seals on T4s commonly deteriorate, and ensure the vehicle has no warning lights illuminated on the dashboard before completing any purchase decision.
