2015 Porsche Panamera 3.0L Diesel · SX54 GOO

The vehicle remains roadworthy, but the maintenance history reveals a persistent and unresolved issue regarding the braking system. The most recent test in September 2025 at 85,466 miles again flagged corrosion on both the nearside and offside front brake pipes, notably covered in grease. This specific defect has appeared in every annual MOT record since 2022, indicating that while the vehicle passes the test, the underlying corrosion has not been addressed or replaced. The trend is stable in its failure rather than improving. The mileage pattern is consistent with a vehicle of this age, averaging approximately 7,770 miles per year. Between the 53,234 miles recorded in August 2021 and the 85,466 miles in September 2025, the car covered over 32,000 miles. This steady usage suggests regular operation rather than long periods of stagnation, which is generally beneficial for seals and rubber components. However, the accumulation of mileage correlates directly with the increasing wear of consumables such as brake pads and tyres noted in the later records. A buyer must conduct a thorough physical inspection of the brake lines to ensure the corrosion has not compromised the structural integrity of the pipes. The presence of grease on the corroded sections suggests an attempt to mask rust or a leak from a nearby component, which warrants a close mechanical check. Furthermore, the 2024 advisory regarding rear tyres being worn on the edge indicates potential alignment issues or suspension bushing wear that should be verified. Given the recurring nature of thin brake pads noted in 2023, a full assessment of the remaining braking hardware is required prior to purchase.
