2020 Audi A4 Technik 35 TDI S-A 2.0L Diesel · HA11 STG

The latest DVSA MOT test for the 2020 Audi A4 Technik 35 TDI S-A was conducted on 2026-08-11 and resulted in a passing grade, though it included a single advisory regarding the near-side rear lower coil spring mounting. This advisory, classified under 5.3.1(b)(i) for structural integrity, indicates that the spring’s mounting has suffered minor damage but remains functional without posing an imminent risk to roadworthiness. The MOT history over the preceding four years shows no previous failures or recurring issues, suggesting a stable maintenance profile. The absence of repeated defects or advisories over this period implies that the vehicle has generally maintained compliance with roadworthiness standards, though the current advisory warrants closer attention to prevent potential long-term wear progression on the suspension system. The recorded mileage of 54,269 miles for a 2020 model represents a reasonable annual usage rate of approximately 9,045 miles per year, aligning closely with typical driving patterns for this age group. This figure does not suggest excessive wear from high mileage alone, as the vehicle has not accumulated significantly more miles than would be expected from moderate, regular use. However, the slight discrepancy between the stated mileage and the implied usage rate—particularly if there were extended periods of inactivity—could indicate potential standing corrosion risks, especially in areas prone to moisture exposure, such as wheel arches, undercarriage seals, and the engine bay. Additionally, the suspension’s wear, as highlighted by the recent advisory, may be influenced by prolonged periods without dynamic loading, which can accelerate bush and spring degradation over time. For a prospective buyer, the most critical inspection areas should focus on the suspension system, given the advisory concerning the near-side rear coil spring mounting. On a test drive, listen for unusual clunking or rattling noises from the rear suspension, particularly when transitioning between smooth and uneven road surfaces, as these may indicate further wear in the mounting or bush components. Visually inspect the coil springs for signs of excessive sagging or distortion, which could suggest internal failure or continued mounting damage. Additionally, check for any oil or grease stains around the spring mounts, which may indicate leakage from adjacent components like the shock absorbers or control arms. Beyond the suspension, conduct a thorough examination of the vehicle’s undercarriage and wheel wells for signs of corrosion, particularly in areas that may have been exposed to moisture for extended periods. The engine bay and exhaust system should also be inspected for fluid leaks, as the TDI diesel engine is prone to coolant and oil leaks that can degrade performance and safety over time. Given the vehicle’s age and the advisory on the coil spring, consider scheduling a pre-purchase inspection by a qualified mechanic to assess the suspension’s overall condition, including the integrity of the remaining bushings and the alignment of the rear suspension geometry. For fluid servicing, ensure that the engine oil, coolant, and brake fluid have not exceeded their recommended service intervals, as these fluids can degrade over time even without significant mileage accumulation. Lastly, verify the condition of the tyres, paying particular attention to sidewall wear and cracking, which can become critical in older vehicles due to the effects of age and environmental exposure.
