2018 Volkswagen Tiguan 2.0L Diesel · BC18 HTD

The vehicle presents a concerning maintenance trend regarding its braking system and suspension components. While the most recent test on 7 April 2026 at 55,660 miles resulted in a pass, the advisory list indicates a significant deterioration in brake condition. Every disc on the vehicle, both front and rear, was flagged as worn, pitted, or scored with heavy corrosion on the inner faces. The tester also noted thin rear brake pads. This follows a pattern of recurring brake disc corrosion and thinning pads seen in the 1 April 2025 test at 46,680 miles, suggesting that while the vehicle remains legal, the braking hardware is nearing the end of its serviceable life. The mileage accumulation appears consistent with the vehicle's age, averaging roughly 7,000 miles per year. The record shows a steady progression from 34,033 miles in March 2023 to 55,660 miles in April 2026. This relatively low annual mileage may explain the heavy corrosion observed on the brake discs, as vehicles driven fewer miles often suffer from surface oxidation due to less frequent, high-temperature braking events. The jump from 40,000 miles in February 2024 to 46,506 miles in March 2025 shows a normal usage pattern, though the failure in March 2025 highlights a period where maintenance was deferred. A prospective buyer must prioritise a physical inspection of the braking system and the underside of the vehicle. The recurring advisories for pitted and scored discs, combined with the 18 March 2025 failure involving a fractured offside rear coil spring, indicate that suspension and braking components require close scrutiny. The presence of lower under trays obscuring components has consistently hindered full inspections since at least February 2024, meaning a technician should ideally remove these trays to check for genuine structural corrosion or fluid leaks. The failure in March 2025 regarding an inoperative Engine MIL (Malfunction Indicator Lamp) also warrants investigation to ensure all dashboard warning lights function correctly and no underlying engine management issues remain. Given the heavy corrosion noted on the brake discs in the most recent test, a full replacement of discs and pads across all four corners is likely necessary in the near future. Focus should also be placed on the rear tyres, which were flagged as being near the legal limit in both March and April 2025.
