2009 Volkswagen Phaeton 3.0L Diesel · LD59 TVT

The 2009 Volkswagen Phaeton presents a mechanical picture defined by an alternating pattern of passing and failing MOT tests over the past three years, culminating in a clean result on 2025-09-18. Two consecutive failures occurred in September 2024, followed by a mixed 2025 where the vehicle passed on one occasion before failing again later that month, suggesting persistent underlying issues rather than isolated incidents. The latest test on 2025-09-18 showed the vehicle still requiring attention despite prior remediation efforts, with the engine showing ongoing malfunction and critical tyre deterioration across multiple axles. This trajectory indicates that while the immediate hazard level has decreased since mid-2024, fundamental problems remain unresolved and require careful consideration before purchase. At 138,115 miles on a 2009 model, the vehicle accumulates approximately 8,124 miles annually, which aligns reasonably with its age and does not immediately signal abnormal wear patterns. There are no dramatic spikes in mileage between the 2024 and 2025 test dates, nor any period of extended lay-up that would suggest sudden acceleration of consumption. The gap between the 2024-09-20 and 2025-09-18 tests spans several months, during which the vehicle remained operational but was subject to intermittent mechanical stress evidenced by the repeated engine misfire and tyre issues. This steady but unremarkable usage profile means the majority of the vehicle's mechanical life should be intact, though the quality of that life is compromised by the documented failures. The nearest front tyres were flagged as slightly damaged on the 2025-09-18 pass, and both the 2024-09-20 and 2025-09-18 fails highlighted severe tyre deterioration including exposed ply or cords on the offside front tyre and worn inner tyres on both sides of the rear axle, with one set of rear inner tyres falling below the legal minimum tread depth of 1.6mm. These conditions point to progressive wear in the suspension bushings, control arm bushings, and possibly subframe attachment points, which are prone to fatigue and corrosion over time. Additionally, the engine is consistently reported as inoperative or indicating a malfunction, which warrants investigation into potential ignition timing, fuel delivery, or compression issues that have not been resolved through repairs. The offside front windshield washer problem, while less critical, indicates a secondary electrical or pump-related fault that may affect driver convenience and visibility reliability. For a prospective buyer, the engine misfire represents the highest priority concern and should be addressed with a full diagnostic before committing to this vehicle, as ongoing engine faults can escalate to costly repairs or compromise safety. The tyre situation requires immediate attention, particularly the exposed ply on the front tyre and the critically short tread on the rear inner tyres—both present genuine safety risks that exceed legal limits and demand replacement of the affected tyres and likely suspension components. Given the repeated nature of the failures, especially the engine MIL appearing in back-to-back test cycles, the vehicle shows signs of accumulated mechanical degradation that may outpace normal wear for its age. A thorough pre-purchase inspection should focus on confirming resolution of the engine issue, verifying tyre replacement and alignment, checking for any emerging subframe or suspension corrosion, and ensuring the windshield washer system functions properly. If these areas are not fully resolved, the financial and safety implications of proceeding with this purchase become substantial.
