2020 Audi A4 Sport 30 TDI S-A 2.0L Diesel · LS20 AXR

The most recent MOT test on 2026-08-19 resulted in a clean pass, indicating that the vehicle has met all current roadworthiness standards at that time. However, the overall maintenance history reveals a concerning pattern of recurring issues. The vehicle failed its last MOT in 2023-03-11 due to a fractured nearside rear coil spring, a critical structural component that compromises ride quality and handling stability. This failure was not rectified before the subsequent MOT in 2024-03-11, where only an advisory was noted for front brake pads wearing thin, suggesting that the spring issue may have been overlooked or not addressed promptly. The subsequent MOTs in 2025-03-15 and 2026-03-17 remained clean, but the presence of a fractured coil spring—particularly at this mileage—indicates either a design flaw, substandard maintenance, or accelerated wear from heavy or aggressive driving. The advisory for nearside front tyre wear close to the legal limit further implies that the vehicle has been driven with insufficient attention to tyre management, potentially exacerbating other wear patterns. The vehicle’s recorded mileage of 103,615 miles for a 2020 model represents a high annual usage rate of approximately 17,269 miles per year, which is unusually aggressive for its age. Such mileage accumulation typically accelerates wear on critical components such as suspension systems, brake systems, drivetrain elements, and internal engine parts. The nearside rear coil spring failure at this mileage suggests that the vehicle has either been subjected to excessive stress, possibly from rough road conditions, heavy loads, or prolonged periods of high-speed driving. Additionally, the thin brake pads advisory implies that the braking system has been underutilised or that the vehicle has been driven in a manner that delays necessary maintenance, leading to premature wear. The lack of service records or mileage gaps to indicate periods of reduced usage further suggests that the vehicle has been in frequent, demanding service, which is not typical for a six-year-old car and warrants closer inspection of wear progression. Given the history of coil spring failure and recurring advisories, the prospective buyer should prioritise a thorough mechanical inspection of the suspension system. The fractured nearside rear coil spring is a major concern, as it indicates a structural weakness that could lead to further damage if not repaired. During a test drive, listen for unusual noises such as clunks or rattles in the rear suspension area, particularly when cornering or over bumps, as these may signal further coil spring or mounting issues. Inspect the rear suspension for any signs of excessive play or binding, and check for uneven tyre wear patterns that could suggest misalignment or suspension misalignment. The thin brake pads should be addressed immediately, as they may require replacement before they become unsafe. Listen for brake noise, vibration, or a spongy pedal during braking, which could indicate warped discs or hydraulic issues. Additionally, verify that the brake fluid level is adequate and that there are no leaks around the brake calipers or master cylinder. Beyond the immediate mechanical concerns, the buyer should conduct a comprehensive physical inspection of the vehicle’s condition. Given the high mileage and the history of wear-related issues, check the tyres for signs of sidewall cracking or perishing, which can occur from prolonged exposure to UV light and age-related degradation. Inspect the exhaust system for leaks or excessive noise, as emissions-related advisories or failures could become a major issue if not addressed. Verify that the 12V battery is in good condition, as prolonged periods of disuse or high demand from electrical accessories can lead to battery failure. Check for signs of corrosion on the brake discs, especially on the nearside rear, where the coil spring failure may have contributed to standing corrosion or binding calipers. Finally, ensure that all fluids—oil, coolant, brake fluid, and transmission fluid—are at the correct levels and are not showing signs of degradation or contamination. Given the vehicle’s age and usage profile, a full service history check, including timing belt replacement (if applicable) and fluid refreshes, should be confirmed before purchase.
