2020 Volkswagen Tiguan R-Line Tech TDI 2.0L Diesel · FA15 AAN

The most recent MOT test conducted on 2026-06-11 resulted in a passing outcome, indicating that the vehicle met all current roadworthiness standards at that time. However, the preceding MOT history reveals a pattern of recurring issues, particularly concerning the suspension system. The vehicle failed its 2026 test due to a major defect in the offside rear coil spring, which is a critical component for maintaining vehicle stability and load distribution. This failure highlights a persistent structural weakness in the suspension, as it was also noted as a corroded rear coil spring in the 2025 MOT with an advisory, suggesting ongoing degradation despite previous servicing. While the 2024 and 2023 tests passed without defects, the presence of advisories and the immediate subsequent failure underscore a trend of accelerated wear in this area, warranting immediate attention. The recorded mileage of 90,528 miles for a vehicle aged approximately six years represents a relatively high annual mileage of around 15,088 miles, which is notably elevated for its age. Such usage typically accelerates wear on consumables like brake pads, tyres, and fluids, as well as structural components such as suspension bushes, coil springs, and exhaust systems. The absence of significant mileage gaps suggests the vehicle has been in active use, which can lead to more rapid degradation of components exposed to constant stress, such as the rear coil springs and shock absorbers. The high mileage also implies that the vehicle may have undergone rigorous driving conditions, potentially including off-road or rough terrain, which could exacerbate wear on suspension and drivetrain elements. Given the history of suspension-related defects and advisories, the prospective buyer should conduct a thorough inspection of the vehicle’s suspension system. Focus on the rear offside coil spring, which failed the latest MOT, and the near-side front shock absorbers, which showed light misting of oil in the 2025 test. Symptoms to watch for during a test drive include excessive body roll or sagging on the offside rear, clunking or rattling noises from the suspension, particularly when driving over bumps or at speed, and uneven tyre wear patterns that may indicate misalignment or suspension misalignment. The buyer should also inspect the coil springs for any signs of further corrosion, cracking, or physical damage, as these can compromise structural integrity and lead to catastrophic failure. Immediate replacement of the failed coil spring and assessment of the remaining suspension components are strongly advised to prevent further roadworthiness issues. In addition to the suspension, the buyer should verify the condition of the brake system, given the high mileage and potential for standing corrosion. Check for signs of binding calipers, warped or grooved brake discs, and uneven brake pad wear, as these can indicate prolonged use or standing in one position. Inspect the brake fluid reservoir for contamination or low levels, and consider a brake fluid flush if the vehicle has been stationary for extended periods. The tyres should be examined for sidewall perishing or cracking, which can occur over time even with low mileage, and ensure they meet the minimum legal tread depth of 1.6mm. Given the vehicle’s age and usage, the 12V battery should be tested for strength, as prolonged idling or high mileage can accelerate battery degradation. Finally, the engine oil and coolant should be checked for signs of degradation, such as sludge buildup or coolant contamination, and a service history review should confirm that time-based fluid servicing has been conducted according to manufacturer recommendations. If the vehicle has been driven under varied conditions, an exhaust emissions test may also be prudent, particularly if the TDI engine is known to be prone to catalytic converter or DPF issues.
