2018 Audi A6 2.0L Diesel · SP11 ATT

The latest DVSA MOT test for the 2018 Audi A6 was conducted on 2026-06-25, resulting in a passing grade. While the vehicle has maintained its roadworthiness through each subsequent test, the recurring advisories—particularly regarding brake pad wear, tyre condition, and disc lipping—suggest a pattern of gradual but persistent mechanical degradation. The absence of any failures or critical defects indicates that the vehicle is currently compliant with roadworthiness standards, but the advisories highlight areas where wear is approaching or exceeding service thresholds. This trend, over the past four years, points to a vehicle that requires consistent attention to consumable components and preventative maintenance rather than one that is failing catastrophically. The recorded mileage of 72,783 miles for an eight-year-old A6 represents a moderate annual usage rate of approximately 9,098 miles per year, which is within the expected range for this model’s age and typical driving conditions. Lower mileage could imply periods of less frequent use, potentially leading to issues such as standing corrosion in the brake systems, suspension components, or underbody elements, while higher mileage would accelerate wear on brake pads, tyres, suspension bushes, and drivetrain lubricants. Given the consistent mileage progression, the vehicle’s wear profile is likely influenced by regular use rather than prolonged idleness, though the 70% wear on both front and rear brake pads suggests that brake maintenance should be prioritised to avoid premature disc failure or reduced braking efficiency. As a prospective buyer, the most critical areas to inspect are the braking system, tyres, and suspension, given the recurring advisories. Begin by visually and physically examining the brake discs for signs of excessive lipping, which can indicate overheating or uneven wear. Listen for any unusual noises during braking, such as grinding or squeaking, which may signal pad-to-disc contact or warping. Test the braking action under various conditions—including hard stops and gradual deceleration—to assess overall performance and ensure no binding or uneven stopping. The rear tyres, particularly the near-side and off-side, show significant edge wear, which could stem from underinflation, misalignment, or excessive camber angles. Check tyre tread depth with a legal tread depth gauge, and inspect for signs of uneven wear patterns that might suggest alignment or suspension issues. Additionally, verify tyre sidewall condition for cracks or perishing, which can weaken the tyre structure over time. Beyond the advisories, the vehicle’s age and mileage warrant a thorough inspection of fluid levels and condition, particularly the engine oil, brake fluid, and coolant. Given the A6’s design, the engine oil should be checked for metallic particles or sludge, which could indicate wear in the crankshaft or camshaft bearings. The brake fluid reservoir should be topped up and tested for contamination or moisture buildup, as this can compromise braking performance. The coolant system should be inspected for leaks or corrosion, especially around the radiator hoses and water pump, as standing fluids can degrade over time. For the suspension, check the condition of coil springs and shock absorbers for signs of leakage or excessive compression, and listen for clunking noises when driving over bumps, which may indicate worn suspension bushes or damaged strut mounts. Finally, verify that all service records are up to date, particularly for the timing belt replacement, which is critical for the Audi A6 to prevent catastrophic engine failure. If the vehicle has been in storage, consider a more rigorous inspection for corrosion on the undercarriage, wheel bearings, and exhaust system, as prolonged idleness can accelerate these issues.
