2015 Audi S8 4.0L Petrol · AE64 KHT

The most recent MOT, dated 20 May 2022, was a pass but it recorded a number of advisories concerning tyre condition, a slightly distorted front wheel and wear on the front upper suspension arm bushes. The preceding test on 14 May 2022 had failed on headlamp aim and carried the same suspension advisories, while the 2019 tests showed a dangerous rear‑tyre failure that was subsequently replaced. Overall the maintenance record shows a mixed picture: serious safety defects have been rectified, yet recurring wear items such as tyres and suspension bushes continue to be flagged, indicating a maintenance trend that is stable but not improving. At 116,807 mi the car averages just over 10,600 mi per year, which is typical for a 2015 model. There are no obvious large mileage gaps in the MOT record, suggesting the vehicle has been used consistently rather than sitting idle for long periods. This level of use places normal wear on consumables – tyres, brake pads and discs, and suspension components – and means that age‑related degradation of rubber and fluid seals should be expected alongside mileage‑related wear. When inspecting the car, give particular attention to the four tyres. Verify that tread depth exceeds 3 mm on all corners, examine sidewalls for cracking, dry rot or embedded nails, and confirm that the wheels are true with no wobble that could have caused the earlier distortion advisory. During a test drive listen for clunking or knocking over bumps, which would indicate the front upper suspension arm pins or bushes are nearing the end of their service life, and feel for any pull or vibration that might stem from uneven tyre wear. Check that the headlamps are correctly aimed – a mis‑aimed beam will reduce night‑time visibility and may require an alignment adjustment – and confirm that the wiper blades now clear the windscreen effectively. Given the vehicle’s age, also examine the condition of the brake discs and pads for surface rust, scoring or glazing, and test for any pulsation or shudder when applying the brakes. Inspect the 12 V battery for signs of sulfation, low cranking voltage and ensure the terminals are clean; a battery over ten years old may need replacement even if it appears to hold a charge. Finally, verify that the coolant, brake fluid and engine oil have been changed at the recommended intervals, looking for discoloured or milky fluids that would indicate contamination, and check for any corrosion on chassis mounting points or underbody panels that could have resulted from prolonged standing. A thorough visual and road‑test inspection addressing these points will give a clear picture of the car’s current roadworthiness and any imminent maintenance that a buyer should budget for.
