2020 Audi A3 S Line 35 Tfsi 1.5L Petrol · CD18 REY

This 2020 Audi A3 S Line 35 TFSI presents a clean and stable maintenance trend across its entire MOT history. The most recent test, conducted on 3 February 2026 at 15,633 miles, passed with zero defects recorded. This follows a consistent pattern of four consecutive passes with no advisories or failures, indicating the vehicle has been maintained to a high mechanical standard throughout its life. The trend is stable and shows no signs of deterioration. The mileage accumulation is notably low for a six-year-old vehicle. Between the first recorded test on 15 September 2023 at 11,394 miles and the most recent on 3 February 2026 at 15,633 miles, the car covered just 4,239 miles over approximately two years and five months. The annualised average sits at roughly 2,606 miles per year, well below the UK typical of 8,000 to 12,000 miles. This suggests predominantly short urban journeys or extended periods of inactivity. Low mileage can preserve mechanical components, but prolonged standing risks flat-spotted tyres, brake surface corrosion, and dried-out rubber seals. Despite the clean MOT record, a prospective buyer should still conduct a thorough physical inspection. The absence of any flagged defects is encouraging, yet MOT tests only capture a snapshot. Check the condition of all four tyres for uneven wear or perishing, given the low annual mileage and potential for ageing rubber. Inspect the brake discs and pads for surface corrosion, which can develop quickly on a vehicle used for short trips. Examine the underside for any early signs of corrosion on suspension components, subframes, and exhaust mounting points, particularly if the car has been stored or used in areas with road salt exposure. The S Line suspension sits lower and firmer than standard A3 setups, so listen for clunks or knocks from front lower arms and anti-roll bar linkages over speed bumps. Verify the operation of the turbocharger and intercooler pipework under load, as the 35 TFSI engine can suffer from boost leaks on higher-mileage examples. Given the clean history, this vehicle appears mechanically sound, but a pre-purchase inspection by an independent specialist remains prudent to confirm long-term structural integrity and drivetrain health.
