2015 Volkswagen Tiguan 2.0L Diesel · X2 LWD

The most recent MOT test on 7 January 2026 resulted in a pass, although three items were noted that warrant careful attention. The advisories on both rear shock absorbers showing light oil misting indicate the early stages of seal wear, a condition that typically progresses over time and may eventually lead to a noticeable deterioration in ride quality and rear-wheel stability. The minor defect recorded against the nearside front outer CV joint boot is a more pressing concern, as a severely deteriorated boot will allow water and grit ingress into the constant velocity joint, leading to accelerated wear of the joint internals and potential failure if not addressed promptly. Despite these items, the broader pattern of MOT outcomes over recent years shows a clear progression: the 2023 test recorded the first advisories for rear suspension arm corrosion, which escalated to major failures in January 2024, requiring remedial work before the vehicle passed just two days later. Since that repair, the 2025 test returned a clean pass with no advisories, suggesting the corrosion issues have been rectified, though the rear shock and drive shaft advisories from the latest test indicate that consumable wear is now beginning to surface in other areas. The recorded mileage of 79,820 miles over approximately eleven years equates to an annual average of around 7,256 miles, which is broadly typical for a vehicle of this age and category. There are no unusual gaps or significant periods of standing evident from the MOT record, with tests conducted at reasonably regular intervals. This consistent usage pattern is generally favourable from a mechanical standpoint, as it suggests the vehicle has been driven regularly rather than left to deteriorate through disuse, mitigating some of the risks associated with calendar-based degradation of seals, brake components, and fluid systems. However, the cumulative mileage is now at a point where several major service items are likely due or approaching, including timing belt replacement on the diesel variants common to this model, brake fluid renewal, and potentially coolant and automatic transmission fluid changes if applicable. For a prospective buyer, the recurring theme of rear suspension corrosion identified in 2023 and 2024 demands close physical inspection, even though the vehicle currently appears to have passed on those points. On a test drive, listen for any clonks, knocks, or knocking sounds emanating from the rear suspension, particularly when traversing speed bumps, potholes, or uneven road surfaces, as these symptoms would suggest that the previously repaired components may require further attention. The rear shock absorbers showing oil misting should be checked for any reduction in damping performance, which would manifest as excessive rear-end bounce when pressing down on the boot or a more unsettled ride over undulating roads. The deteriorating CV boot on the nearside front should be inspected visually and the joint itself assessed for any clicking or knocking when turning at full lock, a classic symptom of grease loss and internal joint wear. Given the vehicle's age of eleven years, even with moderate mileage, several age-related items warrant thorough physical verification regardless of the MOT record. Tyres should be examined not only for tread depth but for sidewall cracking, perishing, and any bulges, as rubber compounds degrade with time irrespective of wear, and budget for replacement if they show signs of age-related deterioration. The 12-volt battery should be tested for its state of health, as batteries typically require replacement every five to seven years and the original unit is well beyond this service life. Brake discs, particularly those that have been standing idle for extended periods, should be checked for severe corrosion on the outer edges and friction faces, while ensuring that the calipers are not binding, which would manifest as uneven braking or pulling to one side under moderate pressure. Finally, verify the timing belt or chain service history, as replacement intervals for the 2.0-litre TDI engine are typically every five years or 75,000 miles, and confirm that all fluid services including brake fluid, coolant, and gearbox oil have been conducted in line with manufacturer recommendations, as these are time-sensitive items that do not always coincide with mileage-based service triggers.
