2020 Volkswagen Touran 1.5L Petrol · GF70 CKA

A recurring theme of front brake disc corrosion runs through the otherwise unblemished MOT history of this 2020 Volkswagen Touran, with advisories logged at both the 2023 and 2025 tests describing pitting, scoring and inner-face corrosion on the front discs. The most recent examination on 12 September 2025 returned a pass with a single advisory noting both front brake discs corroded on their inner faces, mirroring the wording of the 2023 entry and indicating that surface oxidation on the discs is a persistent characteristic rather than a one-off finding. The intervening test in September 2024 recorded no defects, so the overall roadworthiness picture is stable at pass level, but the front braking hardware has been the only area repeatedly flagged across three consecutive annual examinations. No structural, suspension, exhaust or lighting advisories have been recorded, and the vehicle has never failed an MOT. With 19,095 miles accumulated over six years, the Touran has covered approximately 3,182 miles annually, a notably low figure for a family MPV of this type. The mileage progression between tests is incremental and consistent, showing roughly 3,000 to 3,500 miles added each year between 2023 and 2025, with no unexplained jumps or gaps in the recorded readings. Mechanically, this modest annual usage means the engine, transmission and drivetrain components are unlikely to have suffered high-cycle wear, but it does mean the vehicle has spent long periods undertaking only short journeys. Front brake discs that corrode on their inner faces while still passing the minimum thickness standard are typical of cars used predominantly for low-speed, low-effort driving, where the pads do not generate enough heat or rotational friction to keep the iron discs clean of surface rust. For a prospective buyer, the priority on inspection should be the front brake system. On a test drive, listen for any grinding, scraping or rhythmic squeal from the front wheels that would suggest the corrosion has progressed beyond surface oxidation into lipping or hot-spots on the disc surface. Feel for brake pedal judder or vibration through the steering wheel under firm stopping, which would indicate disc runout caused by uneven corrosion wear. At low speed, particularly after the car has been standing in damp conditions, an initial period of binding or roughness before the brakes smooth out is consistent with the advisory pattern, but persistent roughness, any visible lip on the disc edge, or a pulsating pedal under normal braking would warrant disc replacement before purchase. A physical check of disc thickness with a vernier gauge, comparing it against the stamped minimum thickness on the disc bell, will establish remaining service life. The remainder of the mechanical evaluation should focus on confirming the absence of issues that the MOT record does not cover. Inspect the condition of the front brake pads, as low-mileage use with disc corrosion can sometimes lead to uneven pad wear or glazing. Examine the underside for any oil misting or seepage around the engine and gearbox, as low annual mileage can allow minor leaks to develop over time without being noticed. Check that all suspension components are free from knocking over speed bumps and that the steering is precise without pulling, given that no suspension defects have been recorded in the history. Finally, confirm that all electrical systems, including the infotainment and rear parking sensors common to the Touran, operate correctly, as these are not assessed under the MOT test but are relevant to overall vehicle usability.
