2005 Volkswagen Touareg 2.5L Diesel · FD55 RMY

Chronic emissions failures and progressive underbody corrosion define the mechanical profile of this vehicle. While it achieved a pass on 23 September 2025, the history reveals a struggle to meet roadworthiness standards, including a dangerous failure regarding braking lights and repeated major failures for excessive exhaust emissions throughout 2024 and 2025. The current status is a pass, but the record shows a trend of deteriorating structural integrity and engine efficiency. With 151,979 miles recorded over 21 years, the vehicle has averaged approximately 7,237 miles per year. This usage pattern is typical for its age, suggesting a consistent level of wear across the drivetrain and chassis. At this mileage, high-stress components such as the turbocharger, injectors, and suspension linkages are likely reaching the end of their optimal service life, which aligns with the recurring emissions and bushing issues noted in the test history. Immediate attention is required regarding the chassis and suspension. The most recent tests highlight general underbody corrosion, a corroded fuel tank strap, and a rear sub-frame that is corroded and suffers from worn pins and bushes. During a test drive, listen for knocks or clunks when traversing uneven surfaces or during low-speed manoeuvres, as these are indicative of the failing sub-frame bushings. A visual inspection of the underbody is essential to determine the extent of the corrosion and whether the structural integrity of the sub-frame is further compromised. Engine and drivetrain health should be scrutinized due to the persistent smoke levels and recorded oil leak. The recurring failure of the exhaust emissions test suggests an underlying issue with the fuel system or engine internals that may not have been fully rectified. Observe the exhaust during hard acceleration for excessive smoke and check the engine bay and driveway for fresh oil deposits. Additionally, ensure the nearside front outer drive shaft joint has been properly serviced following the reported deterioration of the constant velocity boot to avoid premature joint failure.
