2020 Audi A4 S Line Black ED 35 TDI S-A 2.0L Heavy oil · LS20 OFJ

The most recent DVSA MOT test on 2025-08-11 resulted in a clean pass, marking a return to full compliance after a failure observed just over a year prior. While the 2024-06-13 MOT revealed multiple major and dangerous defects—including a front tyre tear, a malfunctioning tyre pressure monitoring system (TPMS), and a faulty supplementary restraint system (SRS) warning lamp—the subsequent tests in 2023-06-07 and 2025-08-11 indicate a resolution of these issues, suggesting either corrective maintenance or natural wear progression that no longer poses immediate risks. The pattern of failures and subsequent passes suggests the vehicle has undergone necessary repairs to address structural tyre integrity and electrical system faults, though the buyer should remain vigilant regarding the tyre’s history and the TPMS’s long-term reliability. The recorded mileage of 8,215 miles for a 2020 A4 represents a relatively low annual usage rate of approximately 1,369 miles per year, which is unusually low for a vehicle of this age. Such low mileage often correlates with periods of stationary use, particularly if the vehicle was parked in a garage or exposed to environmental conditions that accelerate wear from standing. While low mileage can reduce mechanical stress on components like brakes, suspension, and drivetrain, it also raises concerns about hidden issues such as corrosion from prolonged exposure to moisture, particularly in the wheel arches, exhaust system, and undercarriage. Additionally, the lack of recent high-mileage activity means consumables like brake pads, tyres, and fluids may not have been subjected to the wear and tear associated with regular driving, potentially masking underlying problems that would become apparent under normal usage. Given the vehicle’s history of tyre-related failures and the low annual mileage, the buyer should prioritise a thorough inspection of the front tyres, especially the one that failed the 2024-06-13 MOT due to structural tear. This tyre should be completely replaced, as a torn sidewall cannot be repaired and poses a catastrophic risk of sudden blowout. During the test drive, listen for any unusual noises from the front wheels, such as clunking or uneven tyre wear patterns, which could indicate misalignment, suspension wear, or camber issues. The TPMS malfunction from the failed MOT may persist, so verify its functionality by checking the tyre pressures manually and ensuring the system’s warning light does not illuminate during acceleration or braking. Additionally, inspect the brake system for signs of corrosion on discs and calipers, particularly on the nearside rear where the 2024 MOT noted a tyre issue—standing brakes can cause rust buildup and binding, leading to reduced braking efficiency. For the buyer’s practical inspection, focus on the vehicle’s age and low-mileage usage profile. Check the tyre sidewalls for signs of perishing or cracking, which can occur from prolonged exposure to UV light and temperature fluctuations, even at low mileage. Verify the 12V battery health by ensuring the engine cranks smoothly and the lights operate fully; low mileage can sometimes mask battery degradation, but a weak battery may fail suddenly under load. Inspect the exhaust system for leaks or corrosion, especially around the catalytic converter and tailpipes, as standing vehicles can accelerate rust formation. Review the service history for any scheduled fluid changes, such as brake fluid, coolant, and transmission fluid, which should ideally be replaced every 60,000 to 100,000 miles or every 5 years, whichever comes first. Finally, confirm that the service book or dealer records include the mandatory 12-month service at 12,000 miles, as required by Audi’s maintenance schedule, to ensure critical components like the suspension bushes, coil springs, and timing belt (if applicable) have been serviced. If the service book is incomplete, arrange for a full service to address any outstanding items before proceeding with purchase.
