2004 Volkswagen Transporter 1.9L Diesel · CF53 YJB

The most recent DVSA MOT test on 21 April 2023 resulted in a pass, with two minor advisories noted concerning a non-excessive oil leak leaving residue on the undertray and a flat spare tyre. Looking back across the recorded MOT history, the vehicle has consistently passed its annual roadworthiness inspections, with only one recorded failure in June 2017 relating to a harsh-sounding horn, which was presumably rectified promptly as a pass followed three days later. However, the volume and persistence of advisories indicates a vehicle whose underlying consumables and chassis components are showing progressive wear. Recurring themes across multiple tests include corrosion on rear brake pipes, wear in rear wishbone and anti-roll bar D bushes, play in steering rack ends, weeping rear dampers, deteriorated suspension ball joint dust covers, and a persistent gearbox oil leak. While none of these have yet caused a test failure, the cumulative picture suggests a chassis and underbody that have been working hard over a prolonged period and is now entering a phase where multiple components are likely to require attention either individually or as part of a broader suspension refresh. With a recorded mileage of 167,467 miles over approximately 22 years of service, the vehicle has covered an average of around 7,600 miles annually, which is broadly typical for a van of this age and likely working role. There are no extended gaps in the MOT history suggesting long periods off the road, and the mileage progression appears steady rather than erratic. That said, for a T4-generation Transporter approaching its third decade, high accumulated mileage brings inherent wear concerns regarding the engine, gearbox, clutch, turbocharger if fitted, and drivetrain mounts, regardless of how the vehicle has been used year to year. The combination of moderate annual mileage and old age means the vehicle should be evaluated not only on odometer-based wear but also on calendar-related degradation of fluids, rubber components, and electrical systems. Given the recurring advisories across multiple tests, a prospective buyer should carry out a focused mechanical inspection of the suspension and braking systems before purchase. The repeated mentions of anti-roll bar D bushes, rear wishbone bushes, and steering rack end play all point to chassis components that have worn progressively and may now be approaching the threshold where replacement is necessary. On a test drive, listen for clonking or knocking noises from the front and rear suspension over uneven surfaces, particularly when traversing speed bumps or potholes, and pay attention to any vagueness or knocking through the steering wheel which would indicate worsening rack end wear. Inspect the rear brake pipes closely for advanced corrosion, as they have been flagged since at least 2014, and check that the rear dampers are not only weeping externally but also functioning correctly by observing for excessive body roll or continued bouncing after compression. The undertray should be secured properly, as loose undertrays have been a persistent advisory, and the engine and gearbox should be inspected for active oil leaks, particularly given the long-standing advisories regarding oil on the undertray and gearbox oil seepage. Beyond the advisory-driven items, age-appropriate checks remain essential for a 22-year-old vehicle regardless of its MOT status. Tyres should be examined closely for sidewall perishing and cracking caused by age rather than simply tread depth, particularly if the van has stood for any period, and the spare tyre noted as flat in 2023 should be verified as serviceable or replaced. Brake discs should be checked for corrosion ridges on both faces, as standing vans frequently suffer from surface corrosion which can cause shudder under braking even when the discs remain within wear limits. The 12-volt battery should be tested for cranking performance, as batteries of this age commonly fail without warning, and all fluid services should be verified by service history, including engine oil and filter, brake fluid which degrades on a calendar basis regardless of mileage, and coolant. Finally, examine the condition of all visible rubber components including CV boot gaiters, steering rack gaiters, and any cooling system hoses, and confirm the timing belt or cam belt replacement interval has been respected according to manufacturer schedule, as neglect of this item on a high-mileage T4 could result in catastrophic engine damage.
