2004 Volkswagen Transporter 1.9L Diesel · AP04 KVB

The most recent DVSA examination on 4 March 2026 resulted in a pass, which is the immediate positive indicator for any prospective buyer. However, the underlying trajectory over the past four years reveals a vehicle that is being maintained at a borderline level rather than in first-class condition. The earlier failed test in March 2022, which recorded multiple major defects including inoperative stop lamps, insufficient washer fluid, and incorrectly aimed or faded headlamps, was followed the same day by a pass with several advisories covering worn rear brake discs, heavily corroded central exhaust, a corroded rear shock absorber casing, and a nearsely rear tire worn close to the legal limit. Subsequent tests have continued to flag deteriorating drive shaft CV boots on both sides, corroded exhaust outer skin, and a cluster of front suspension advisories relating to lower arm bushes and anti-roll bar D bushes in 2025, alongside a developing ball joint play advisory in 2026. Taken together, this is a maintenance trend that is broadly stable but heavily skewed toward degradation of consumables and underbody components, with several advisories now maturing into areas that warrant active inspection rather than passive monitoring. The recorded mileage of 226,802 miles over a 22-year service life equates to an annual average of roughly 10,300 miles, which sits comfortably within the typical range for a working Transporter of this vintage. There are no obvious gaps in the annual MOT cadence to suggest long periods of standing, which is mechanically advantageous; a Transporter that has been used consistently is generally less prone to seized calipers, perished fuel lines, and severe underbody corrosion than one that has been laid up. That said, 226,000 miles is a substantial accumulation for the T4 platform, and at this odometer reading the buyer should anticipate that major drivetrain items, particularly the engine, gearbox, clutch, and turbocharger if fitted, have lived a full working life and may be approaching the threshold for refurbishment or replacement. Diesel-specific concerns such as injector wear, dual mass flywheel fatigue, and DMF-related vibration should form part of any evaluation, as MOT history cannot speak to internal engine condition. The recurring CV boot deterioration advisories on both the nearside and offside front inner drive shaft joints are particularly noteworthy, as a severely deteriorated boot allows grease to escape and contaminants to enter the joint. Untreated, this leads to CV joint failure, typically announced on a test drive by a rhythmic clicking when turning at low speed, or a shuddering vibration under acceleration. Both sides have now been flagged, so the buyer should physically inspect the boots for splits, perished rubber, or freshly applied grease residue, and budget for replacement if any seepage is evident. The front suspension advisories across 2025 and 2026 point to a progressive wear pattern in the lower arm rear bushes and anti-roll bar D bushes, with the latest test recording slight play in the nearside front lower arm ball joint itself. On a road test, listen for clonking or knocking over uneven surfaces, particularly during low-speed direction changes, and check for uneven front tyre wear patterns that would confirm geometry disturbance from worn suspension linkages. Left unaddressed, these items will progress to MOT failure. The brake system defects and advisories deserve close scrutiny given the rear brake hose ferrules were recorded as excessively corroded at the March 2023 test, a major category failure item. While the immediate repair was evidently undertaken, brake hydraulic components on a 22-year-old vehicle are vulnerable to ongoing corrosion, and the buyer should inspect the entire brake pipe and hose run for surface rust, swelling under pressure, and any signs of recent repair that may mask underlying corrosion. The advisories on rear brake disc wear, nearside rear shock absorber corrosion and limited damping effect, and corroded rear brake pipe all suggest the rear axle is aging faster than the front, so a thorough examination of the rear underbody, spring seats, and caliper slide pins for seizure is prudent. Beyond the recorded history, age-appropriate checks should include tyre sidewalls for perishing and cracking regardless of tread depth, the 12V battery for holding charge under load, the condition and date codes of all fluids including brake fluid, coolant and engine oil, the timing belt or cam belt replacement interval if diesel, and a careful look at the central exhaust system where corrosion has been repeatedly flagged, as the outer skin deterioration often precedes internal bore failure and may necessitate full system replacement.
