2009 Porsche 911 3.6L Petrol · YC59 HWG

The Porsche 911 presents a generally sound mechanical picture, with the most recent MOT on 20 May 2026 at 79,509 miles resulting in a pass. The sole advisory noted a worn rear brake disc, a minor consumable issue rather than a structural or safety-critical defect. Looking at the broader timeline, the maintenance trend appears stable rather than worsening. The 2025 test cycle shows a clear pattern of resolution: the car failed on 13 May 2025 for an exhaust Lambda reading and minor exhaust leak, then passed on the same date after rectification, suggesting the owner addressed the emissions fault promptly. Brake pipe corrosion advisories that appeared in October 2024 were not flagged in the 2026 test, indicating either replacement or that the corrosion remained below the failure threshold. This is a positive trajectory. The mileage profile tells a specific story. At roughly 4,677 miles per year over 17 years, this is notably low annual use. The gap between the October 2024 test at 78,389 miles and the May 2026 test at 79,509 miles shows just 1,120 miles covered in approximately 19 months. That is extremely light use and suggests the car may have stood for extended periods. Long stationary spells can cause its own problems, including flat-spotted tyres, seized brake calipers, and dried-out rubber bushes, even if the mileage figure looks attractive on paper. The 2023 test at 75,889 miles recorded zero defects, so the car was in very clean condition before the recent minor advisories appeared. A buyer should focus the physical inspection on the braking system and underside corrosion. The 2024 and 2025 tests repeatedly flagged corroded front and rear brake pipes, often described as covered in grease or other material, which can mask the true extent of pitting. Even though the 2026 test did not reissue these advisories, the brake discs have shown wear and corrosion across multiple tests, so a close visual check of disc thickness, lip condition, and caliper operation is warranted. The minor exhaust leak near the rear silencer appeared in both 2025 tests and should be verified as fully repaired, with attention to the condition of the rear silencer and lambda sensor function. Tyre condition also deserves scrutiny given the 2024 advisory for inner edge wear on both rear tyres, which points to possible tracking or suspension geometry issues that may have persisted. Finally, given the low mileage and long stationary periods, inspect all rubber suspension bushes, dust boots, and fluid systems for age-related deterioration rather than purely mileage-driven wear.
