2018 Porsche Cayenne 3.0L Diesel · LD18 RVT

The most recent DVSA test on 5 February 2026 resulted in a PASS with no advisories or defects recorded, continuing a notably consistent pattern of clean passes across the last six annual examinations. Between 2021 and 2026, the vehicle has presented without any fail, dangerous, or major defect categories, and the only recorded entries are minor advisories on the 2021 and 2023 tests. This trajectory suggests a stable maintenance regime with no escalating mechanical concerns flagged at the point of test. From an inspection standpoint, a clean pass history of this length on a premium SUV is reassuring, though it is important to recognise that MOT testing is a statutory minimum roadworthiness check rather than a comprehensive mechanical survey, so further due diligence remains essential. With approximately 37,163 miles recorded over an eight-year period, the annual mileage averages around 4,645 miles, which is substantially below the typical figure for a vehicle of this type and considerably lower than what many Cayennes of the same age will have accrued. Such low usage commonly points to either predominantly short urban journeys or extended periods of standing between uses, both of which carry their own mechanical implications. Short journeys prevent the engine, drivetrain, and exhaust system from reaching full operating temperature, which can accelerate oil degradation, promote moisture accumulation in the engine and exhaust, and encourage carbon build-up. Conversely, prolonged standing invites brake disc surface corrosion, sticking or binding calipers, perished rubber components, and premature 12V battery failure, all of which can develop independently of mileage accumulation. Given the limited annual mileage, particular attention should be paid during physical inspection to the condition of the tyres, as rubber compounds degrade with age regardless of tread depth. The 2023 advisory for slight perishing or cracking on the nearside front tyre should serve as a reminder to scrutinise all four tyres and the spacesaver or full-size spare for sidewall cracking, dry rot, and check the production date codes on the sidewalls. The brake system warrants a careful road test, as standing corrosion on the discs can lead to uneven braking, judder through the pedal, or grinding on first application; listen for any scraping noises and feel for a spongy or uneven pedal response. Inspect the visible caliper slides and pad wear, noting that the 2021 advisories flagged thin front and rear pads, meaning a pad and disc refresh may now be due depending on subsequent usage. Also verify the condition of the brake fluid, which is hygroscopic and should be renewed every two years regardless of mileage, and inspect the coolant and transmission fluid service history, as calendar-based servicing remains critical on low-mileage vehicles. Beyond braking and tyres, several other age-related items merit close examination. Check the 12V battery state of charge and load test it if possible, as batteries typically last four to six years and can fail without warning on a vehicle that sees infrequent use. Inspect all suspension bushes, anti-roll bar links, and coil springs for any cracking, sagging, or fluid seepage from the damper units, listening on the road test for clonks over bumps or vibration through the cabin at speed. Examine the underbody, exhaust mounting rubbers, and driveshaft gaiters for corrosion or splitting, paying particular attention to the air suspension system if fitted, as compressor and valve block failures are known concerns on the Cayenne platform. Finally, confirm a complete Porsche main agent or specialist service history with stamps at the correct intervals, evidence of brake fluid, coolant, and PDK or Tiptronic transmission fluid renewals, and review the vehicle for any aftermarket modifications that could compromise structural integrity or emissions compliance before committing to purchase.
