2017 Volkswagen Tiguan 2.0L Diesel · BG67 AFA

This Volkswagen Tiguan has passed its most recent MOT on 2026-07-01 at 78,544 miles, but the test revealed critical corrosion to both rear coil springs—an issue that must be addressed immediately. While the vehicle cleared all other checks at that date, the presence of rust penetration in suspension components signals a latent structural concern. The preceding MOT in 2025-06-21 at 73,961 miles was clean except for defective wiper blades, a minor consumable failure, and the 2024 and earlier tests showed no faults at all. The trend suggests a sudden emergence of serious corrosion rather than a gradual deterioration, though the lack of prior suspension issues makes it impossible to confirm whether this was overlooked or accelerated by environmental exposure. The vehicle’s mileage progression averages around 8,700 miles per year, which is typical for its age, with no extreme gaps or spikes. The most recent 4,583 miles between tests (July 2025 to July 2026) aligns with standard MOT intervals, and there’s no evidence of prolonged neglect or rapid wear. However, the jump from 55,107 miles in 2022 to 64,217 miles in 2023—9,110 miles in a year—was unusually high compared to the subsequent years, which could indicate either heavy usage or a period of inconsistent maintenance. The absence of faults in those earlier tests suggests the vehicle was mechanically sound during that interval, but the corrosion now detected implies either deferred attention to rust or exposure to harsh conditions. A prospective buyer should prioritise a thorough inspection of the rear suspension, particularly the coil springs and mounting points, given the confirmed corrosion. The near-side front wheel distortion noted in the latest MOT also warrants verification—this could stem from impact damage or uneven wear, potentially compromising wheel alignment. While the brakes and drivetrain have not been flagged in recent tests, the lack of advisories in earlier MOTs makes it impossible to rule out hidden issues like worn brake pads or binding calipers. Given the sudden appearance of structural corrosion, a pre-purchase inspection should also check for rust in the subframe, sills, and wheel arches, as well as the integrity of the exhaust system, which is often a secondary indicator of corrosion progression. The wiper blades are a trivial concern, but their repeated failure suggests basic upkeep has been inconsistent.
