2009 Porsche Cayman 3.4L Petrol · RO09 PFG

The most recent MOT on 2026-05-29 resulted in a failure with seven critical issues . The exhaust system failed due to excessive carbon monoxide and Lambda readings, indicating potential engine or emission control problems. Two front tyres had exposed ply or cords, and three tyres (front and rear) had tread depths below the 1.6mm legal minimum. Brake pipes on both front wheels were severely corroded, and the exhaust catalytic converter was missing despite being a standard component. These issues suggest poor maintenance and potential safety risks. A recurring pattern of brake pipe corrosion is evident from 2022 onwards, with progressively worsening conditions. In 2022, brake pipes were corroded and covered in grease; by 2024, outer brake pipes showed severe corrosion; and in 2026, multiple brake pipes were “excessively corroded.” This indicates a persistent issue with corrosion protection, likely due to environmental exposure or inadequate maintenance. The failure to address this over multiple MOTs raises concerns about the vehicle’s structural integrity and safety. Tyre-related failures and warnings have also persisted. Tread depth issues and exposed ply on tyres were noted in 2022, 2023, and 2026, suggesting ongoing neglect or improper tyre maintenance.
