2009 Porsche Panamera 4.8L Petrol · JSV 394

A dominant theme in the MOT record is a series of recurring electrical and tyre‑compliance failures, punctuated by occasional passes that contain no defects. The latest MOT dated 5 December 2025 recorded a major failure of the nearside windscreen wiper and an inoperative engine malfunction‑indicator lamp, while earlier tests flagged lambda‑sensor limits, headlamp‑cleaning inoperability, front position‑lamp failure and sidewall tyre non‑conformity. Although the car has passed on several occasions, the pattern shows intermittent but significant faults rather than a steady improvement in overall roadworthiness. With 60,912 mi logged over 17 years the average annual mileage sits at roughly 3,600 mi, well below typical usage for a performance saloon. Such low utilisation can mean reduced wear on drivetrain and brake components, yet it also raises the possibility of age‑related degradation of seals, rubber bushings and electrical connections that are not mileage‑dependent. The MOT history does not reveal any large mileage spikes, suggesting the vehicle has not undergone periods of intensive use that would accelerate wear, but the modest annual run‑off may have contributed to the tyre sidewall cracking noted in 2023 and the tyre‑type non‑conformities recorded in 2024. Prospective buyers should give particular attention to the windscreen wiper system – verify that the nearside blade clears the glass without streaking and that the motor operates smoothly. The engine’s MIL must illuminate correctly; a diagnostic scan should confirm that the sensor and associated circuitry are functional, especially given the 2025 failure. The lambda sensor’s performance can be assessed by observing idle stability and emissions during a short run, while the headlamp‑cleaning mechanism and all front lighting (position lamp, direction indicators) should be tested for operation and any cross‑talk. Tyre inspection must go beyond tread depth: examine all four sidewalls for cracking, bulging or damage that could contravene sidewall specifications, and confirm that the tyres conform to the manufacturer’s load and speed ratings. Finally, the advisories concerning the undertray, fuel flap and engine covers indicate that some protective panels may be insecure or obstructing inspection points. During a pre‑purchase inspection, ensure the undertray is firmly attached, the fuel flap is stable and the engine covers can be removed without resistance to allow a thorough visual check of the exhaust system, wiring looms and suspension mounting points. Listen for any unusual noises over bumps that could hint at worn suspension bushes or loose subframe components, and feel for any pedal judder that might betray brake‑system wear. Addressing these specific items will give a clearer picture of the car’s current mechanical condition beyond what the MOT entries alone reveal.
