2017 Porsche Panamera 2.9L Hybrid electric · RO07 ANS

The vehicle most recently passed its MOT on 16 October 2025 with two advisories recorded, specifically that both the front and rear brake pads are wearing thin. This represents a stable but cautionary maintenance trend. Earlier tests from 2022 and 2023 were passed with no defects, indicating a period of sound roadworthiness, while the 2020 and 2024 tests showed isolated issues relating to incorrect registration plates and headlamp aim, both of which are minor compliance items rather than indicators of structural or mechanical deterioration. The recurrence of brake pad advisories after clean tests in intervening years suggests normal wear progression rather than any underlying brake system fault, but the front and rear pads reaching a thin condition simultaneously points toward the need for imminent replacement, particularly on a vehicle of this weight and performance capability where stopping distances and brake balance are critical. The recorded mileage of 34,250 miles across nine years equates to an annual average of approximately 3,806 miles, which is exceptionally low for any vehicle and especially so for a luxury performance saloon of this calibre. Such low usage suggests either consistent light use such as occasional touring or weekend driving, or extended periods of standing between uses. The MOT history supports the latter interpretation, showing annual test entries with very little mileage progression implied between tests. While low mileage preserves mechanical components from wear-related fatigue, it carries its own set of risks including standing corrosion on brake discs, oxidation of brake caliper slide mechanisms leading to binding, deterioration of flexible hoses and seals, moisture accumulation in engine and differential oil, and degradation of the 12 volt battery through prolonged partial state of charge. The tyres themselves may also have aged more in calendar terms than they have worn in terms of tread depth. Given the brake pad advisories, a prospective buyer should carry out a thorough inspection of the entire brake system. On a test drive, listen for any grinding or squealing from the calipers, particularly at low speed, which could indicate pads worn to backing plate contact. Feel for any pulling to one side under braking, which may suggest a binding caliper or a seized guide pin, and check for brake shudder through the steering wheel or pedal which would indicate disc warping. Inspect the discs visually for lipping at the outer edge and for any scoring or hot spots, and examine the brake fluid for colour and clarity, as it should be changed biennially regardless of mileage due to its hygroscopic nature. Inspect the tyres carefully for age-related sidewall perishing and cracking, as tyres older than six years should be replaced irrespective of remaining tread, and verify that they are of matching specification across the axle to preserve the vehicle's dynamic stability systems. Beyond the brake system, attention should be given to the items most affected by low mileage and standing use. The 12 volt battery should be load tested, as a battery that has spent long periods partially discharged will have reduced capacity even if it still starts the engine. Coolant and brake fluid should be assessed for age, with brake fluid due for renewal every two years and coolant typically every four to five years depending on specification. With the vehicle being nine years old, the timing chain, intermediate shaft bearing, and any known Porsche-specific ageing issues should be investigated through a specialist pre-purchase inspection, and the full service history verified to confirm that annual oil changes have been carried out regardless of the low mileage. Inspect the exhaust system for surface corrosion, the suspension bushes and coil springs for any cracking or sagging from standing, and the air conditioning system for adequate cooling performance after prolonged inactivity. A compression test and borescope inspection of the cylinders would also be prudent given the low mileage, as engines run infrequently are more susceptible to bore glazing and oil seal drying.
