2018 Volkswagen Tiguan 2.0L Diesel · DU18 ABX

A fractured offside rear coil spring recorded as a major defect at the most recent MOT test on 24 July 2026 dominates the mechanical narrative of this 2018 Volkswagen Tiguan. While a subsequent test on the same date returned a pass with no defects recorded, suggesting the spring had been replaced and the vehicle re-presented, the failure itself cannot be dismissed as a one-off occurrence. Coil springs operate under constant load and rarely fracture without contributing factors such as corrosion, fatigue from heavy loading, or extended service life, so the replacement component and its condition should be verified. The wider MOT history is otherwise relatively clean, with passes recorded in 2023, 2024, and 2025, and only a single advisory issued for worn, pitted, or scored front brake discs at the 2025 test. Taken together, the record shows a largely stable pattern of roadworthiness, punctuated by one significant structural-suspension failure that warrants close scrutiny. With 81,214 miles recorded across approximately eight years of use, this Tiguan has covered an average of around 10,150 miles per year, which sits broadly in line with typical usage for a vehicle of its age and class. There are no multi-year gaps in the MOT testing record, indicating the car has remained in continuous road use rather than being laid up for extended periods, and the relatively consistent annual mileage reduces the likelihood of dried seals, seized calipers, or perished rubber components associated with long-term stationary storage. The mileage accumulation suggests steady, moderate use, but the brake disc advisory from 2025 confirms that consumable wear is progressing at a normal rate and that further attention to the braking system may be required in the near future. Buyers should anticipate that suspension, braking, and drivetrain components will continue to demand routine servicing proportionate to this level of use. For a prospective buyer, the immediate priority is confirming that the fractured offside rear coil spring was replaced with a quality component and that the replacement was correctly seated, as an improperly fitted spring can lead to uneven ride height, premature tyre wear, and compromised handling. On a test drive, listen for any clonking or knocking noises from the rear suspension over uneven surfaces, particularly on undulating roads, and pay attention to any leaning or instability when cornering, which could indicate a weakened or incorrectly specified replacement spring. Inspect the rear tyres for uneven inner or outer shoulder wear, as a fractured or sagging spring frequently produces asymmetric contact patch loading. The new spring and any associated suspension components fitted during the repair should also be checked for corrosion, particularly given the underbody exposure typical of this model. The 2025 advisory regarding front brake discs warrants corresponding attention during inspection. On test, the vehicle should be braked firmly from a moderate speed to feel for any vibration, judder, or pulsing through the brake pedal or steering wheel, which would suggest the discs have worn beyond their service limit or have developed hot spots since the advisory was issued. The brake pedal response should feel firm and progressive, with no sponginess that might indicate caliper binding or hydraulic issues, and the vehicle should pull up in a straight line without deviation. Given the recent coil spring failure, it is also prudent to inspect the rear brake components, handbrake mechanism, and all visible suspension arms and bushes for wear or corrosion, as the additional load imposed by a fractured spring can accelerate degradation of adjacent parts. A thorough underbody inspection, ideally with the vehicle raised, would help confirm the integrity of the replacement spring and surrounding hardware.
