2005 Volkswagen Transporter 2.5L Diesel · LG55 AAN

A persistent theme of corrosion and consumable wear defines the mechanical profile of this 2005 Volkswagen Transporter. Across all five recorded MOT tests spanning late 2021 to December 2025, the vehicle has passed each annual assessment without registering a single failure, yet every test has generated advisories relating to corrosion on the exhaust system, brake pipes, and suspension components. The most recent examination on 12 December 2025 continued this pattern, flagging an offside front tyre worn close to the legal limit, light oil misting on the offside front shock absorber, exhaust corrosion, and notably rusted rear suspension arms. The chronic nature of these advisories indicates a vehicle where surface oxidation and component degradation are progressing steadily rather than being addressed between tests, which is particularly relevant for a Transporter of this age where structural and underfloor corrosion can advance rapidly once established. The recorded mileage of 246,788 miles over approximately 21 years equates to an annual accumulation of around 11,752 miles, which sits broadly within expected parameters for a working van of this vintage. The MOT records show consistent year-on-year testing with no prolonged absences, suggesting the vehicle has remained in regular use rather than being laid up for extended periods. This continuous operational history reduces the risk of issues associated with stationary vehicles such as seized brakes or perished rubber, but the high absolute mileage means wear-related deterioration of major mechanical assemblies including the engine, gearbox, clutch, and drivetrain should be expected. The absence of any mileage-related advisories in the records does not diminish the need for scrutiny of these high-mileage service items during a physical inspection. Given the recurring brake pipe corrosion flagged in every test since 2021, particular attention should be paid to the condition of all flexible and rigid brake lines, with a thorough check beneath the vehicle for any active corrosion, flaking, or signs of recent sealing compound being applied to mask deterioration. The 2021 test recorded severely deteriorated dust covers on the offside front anti-roll bar linkage ball joint, and while no further advisories on this component appear, anti-roll bar bushes and drop links commonly fail on Transporter chassis of this mileage, so any knocking or clonking noises from the front suspension during a road test over uneven surfaces would warrant immediate investigation. The reported oil leak from 2021 should be monitored by checking the underside for fresh drips and the engine bay for accumulating oil residue, with particular care taken to identify whether the leak originates from the cam chain tensioner area, rear main seal, or sump gasket, all known failure points on the T5 platform. The exhaust corrosion advisories across all five tests indicate the system has been progressively deteriorating, and a buyer should physically inspect the exhaust from the catalytic converter rearward for perforations, insecure mounting rubbers, and excessive movement when rocked by hand. Rear suspension arm rust flagged in 2025 requires close inspection of the trailing arm mounting points and inner pivot bushings, as corrosion at these locations can compromise rear axle geometry and tracking, producing uneven tyre wear which ties into the recurring tyre edge wear advisories. During a test drive, listen for any clonking from the rear over speed bumps, check for pulling under braking which may indicate corroded brake pipe restrictions, and feel for any vibration through the brake pedal that would confirm the worn front discs noted in earlier tests. A thorough pre-purchase inspection with the vehicle raised on a ramp is strongly advised given the cumulative pattern of chassis and underbody corrosion.
