2015 Volkswagen Tiguan 2.0L Diesel · BC15 MRY

The 2015 VW Tiguan presents a pattern of recurring mechanical advisories rather than isolated faults, with corrosion affecting the rear lower suspension arms appearing in both 2025 and 2023 MOTs, oil misting detected in the front shock absorbers across multiple assessments from 2023 through 2024, and persistent tyre wear approaching legal limits on all four positions since 2020. The most recent test on 2026-07-22 resulted in a PASS, though it carried two active advisories requiring attention: the nearside and offside rear lower suspension arms were reported as corroded yet not seriously weakened, and the front brake discs showed signs of being worn, pitted or scored but not critically degraded. These findings indicate that while the vehicle has maintained its roadworthiness rating, the underlying mechanical problems have persisted across successive inspections despite no outright failures. At 86,294 miles on a 2015 model year vehicle, the annual accumulation rate of approximately 7,845 miles falls within the normal range for a car of this age, suggesting the odometer reading reflects genuine driving use rather than an unusually high mileage figure. However, the distribution of wear across the test records reveals that tyre degradation has been continuous, with each subsequent MOT showing progressively closer-to-limit conditions on all front and rear tyres, indicating sustained load exposure even when the vehicle appears to be driven moderately. The lack of significant mileage spikes between tests implies the wear patterns are steady rather than episodic, and the absence of sudden jumps suggests the engine and drivetrain have not experienced abrupt acceleration in demand, though the cumulative effect of twelve years of use is evident in the recurring component failures. The recurrent corrosion on the rear lower suspension arms represents the most critical structural concern, as rust can compromise load-bearing capacity and create potential for progressive failure if left unaddressed. During a test drive, inspect the rear suspension arms for any visible flaking or bubbling metal, and pay particular attention to the attachment points where rust might be seeping into the subframe or chassis. Given that this issue appeared in both 2025 and 2023 assessments, it warrants immediate attention before committing to purchase, ideally with evidence of proper treatment or replacement of affected components. Front brake disc wear noted in 2026 along with earlier instances on 2023 and 2022 indicates gradual pad material consumption that should be monitored closely, especially if the vehicle has been subjected to heavy braking loads; during operation, look for any audible squeal or vibration that could signal scoring or glazing. The consistently worn tyres across all four corners suggest either regular short trips keeping tread life down or a genuine reduction in driving distance compared to the initial specification, but this also places additional stress on the suspension system and wheel bearings. A test drive should include checking for any pulling to one side, abnormal noises from the brake calipers, or uneven tyre contact patches that would confirm the tyre wear trends documented in the MOT history.
