2020 Porsche Taycan 4S 79KWH Electricity · AR20 CON

A fault-free DVSA record across four consecutive annual tests, the most recent being a pass on 20 July 2026, presents a strong picture of roadworthiness for this Taycan 4S. With no advisories recorded at any of the 2023, 2024, 2025, or 2026 tests, there is no documented pattern of component wear, corrosion, or marginal defects that have progressively worsened. For a high-performance electric vehicle of this calibre, the absence of recurring brake disc corrosion advisories, suspension component wear notes, or underbody deterioration flags is particularly reassuring. The clean advisory record reflects either genuine component longevity or mileage that has simply not yet induced the wear thresholds at which testers typically raise advisories. Either way, the objective test history provides no immediate mechanical warning signs. Covering 36,354 miles over a six-year service life equates to an annual accumulation of approximately 6,059 miles, which sits squarely within typical usage parameters for a vehicle of this profile. There are no gaps in the MOT testing history, meaning the car has remained registered and presumably in active use throughout its life rather than being placed off the road. This continuous registration pattern is relevant for an electric vehicle because it reduces the likelihood of dormant system faults, degraded coolant systems, or HV battery management issues that can emerge after prolonged storage. The mileage is sufficient to have exercised the braking, suspension, and drivetrain components without pushing them into the high-wear territory where expensive Porsche-specific parts typically begin to demand attention. The relatively modest annual mileage also suggests the regenerative braking system has been doing a significant proportion of the slowing, which should be reflected in the condition of the friction braking components. Given the absence of any specific flagged components in the MOT history, buyer-side due diligence must shift toward the systems and components the MOT scheme does not comprehensively cover, beginning with the high-voltage battery state of health and the electric drive units. A pre-purchase inspection by a specialist familiar with Porsche E-platform vehicles is strongly advisable, focusing on HV battery cell balance, coolant condition for the thermal management circuits, and any diagnostic trouble codes stored across the Porsche systems. The 12V auxiliary battery, which supports control modules and contactor operation, should be checked for resting voltage and load capacity, as a failing auxiliary battery on an EV can manifest in a confusing array of seemingly unrelated electrical faults. The air suspension system, where fitted, should be inspected for strut leaks, compressor cycle times, and any ride-height warning messages, as these components are particularly costly on this platform. On a physical inspection, examine the bodywork closely for stone chips on the front valance and bonnet leading edge, which are common on a vehicle of this performance bracket, and inspect the wheelarch liners and underside of the front splitter for any damage that could affect undertray integrity. The brake discs should be inspected for lipping and surface corrosion, and the callipers examined for any binding or uneven pad wear, particularly given the mixed duty cycle of regenerative and friction braking. On a test drive, listen for any suspension knocks over uneven surfaces, particularly from the rear axle where multi-link components can wear, and pay attention to steering feel for any vibration, pulling, or inconsistent self-centring. Confirm smooth and consistent operation of both forward and reverse gears, listen for any unusual whine or hum from the drive units that could indicate bearing wear, and verify that the regenerative braking transition is seamless rather than producing any noticeable step or judder under light pedal pressure. Finally, ensure all warning systems, including the tyre pressure monitoring system and driver assistance features, calibrate and operate correctly on initial ignition.
