2022 Volkswagen Tiguan R-Line Edition TDI S-A 2.0L Diesel · WH17 EHA

The 2022 Volkswagen Tiguan R-Line Edition TDI S-A presents a clean bill of health on its most recent MOT, passed on 5 December 2025 at 21,156 miles with zero defects recorded. That is a strong result, particularly for a diesel SUV approaching four years of age. With only a single test on file, there is no trend to track in terms of recurring faults or deteriorating items. The maintenance picture is stable but thin, relying entirely on one data point. The mileage profile is notably low. At 21,156 miles over roughly four years, the annual average sits at approximately 5,290 miles, well below the typical UK annual figure of around 10,000 miles. The single recorded test at that exact mileage suggests the vehicle may have covered very little distance in the period leading up to December 2025, or that earlier MOT entries are simply absent from the available record. Low annual mileage can preserve mechanical components, but it also raises questions about whether the diesel particulate filter has been regularly regenerated through sustained motorway driving. Short-trip use in a DPF-equipped diesel can lead to premature filter clogging and associated exhaust emissions faults over time. Buyers should pay particular attention to the condition of the DPF and exhaust after-treatment system during any pre-purchase inspection. A diesel covering fewer than 5,300 miles per year is at elevated risk of incomplete regeneration cycles, which can trigger future emissions-related MOT failures. The undercarriage and suspension mounting points deserve close scrutiny as well. Low-mileage vehicles that spend extended periods stationary can develop surface corrosion on brake discs, exhaust components, and subframe areas, even if the mileage does not suggest heavy use. Tyre condition should also be verified, as infrequent driving can lead to flat-spotting and perished sidewalls despite ample tread remaining. The clean MOT result is encouraging, but it should not substitute for a thorough in-person mechanical inspection. A diesel Tiguan with this usage pattern benefits from a test drive that includes sustained higher-speed running to confirm DPF function, along with a lift check of the underside for corrosion and suspension bush condition. The single-pass record gives confidence, yet the sparse history means a buyer is relying on one snapshot rather than a proven pattern of upkeep.
