2015 Volkswagen Touareg 3.0L Diesel · CX15 MCC

Rear suspension corrosion dominates the MOT narrative, with both rear coil springs flagged for corrosion in the 2025 test, indicating a persistent exposure issue that has not yet escalated to a failure but warrants close scrutiny. The vehicle has otherwise passed every test since 2018, with only advisory notes for tyre wear in 2023 and thin brake pads in 2019, suggesting a generally acceptable roadworthiness record but a specific vulnerability in the rear suspension structure. At 62,587 mi over eleven years the average annual accumulation sits around 5,700 mi, well below the typical UK usage pattern for a vehicle of this age. Such low mileage often points to periods of limited activity or storage, which can accelerate corrosion on exposed components like coil springs, especially in a climate prone to moisture. The steady, modest mileage progression also means consumables such as tyres, brakes and suspension bushings are likely to have experienced less cyclic stress than a high‑mileage counterpart, but the lack of higher mileage does not guarantee the absence of wear in critical safety items. Prospective buyers should inspect the rear suspension for any signs of sagging rear ride height, uneven tyre wear or clunking noises when traversing bumps, which would indicate deteriorating spring integrity or associated mounting points. A visual check for rust on the spring mounts, surrounding subframe and any corrosion‑protected coatings is essential; any excessive rust could compromise the spring’s load‑bearing capacity and may require replacement or reinforcement. While the tyre advisory in 2023 concerned the nearside rear tyre, a fresh tyre inspection should confirm tread depth, uniformity and sidewall condition before committing. Brake pad wear was noted as thin in 2019, yet no further advisories have appeared, implying either replacement or acceptable wear since then. Nonetheless, a buyer should verify current pad thickness, listen for squeal or grinding under moderate braking, and feel for any pedal pulsation that could hint at uneven disc wear. A brief road test should include firm, progressive braking to ensure consistent pedal feel and no judder, confirming that the braking system remains within safe operational limits.
