2021 Audi A4 S Line 35 TDI Mhev S-A 2.0L Diesel · GD21 JWK

This Audi A4 S Line demonstrates a stable roadworthiness record over the past two MOT cycles, with both tests in November 2025 and February 2024 passing without any defects or advisories. The most recent inspection at 32,229 miles confirms no mechanical or structural issues, though the absence of advisories does not preclude hidden wear—particularly in high-mileage components like turbochargers, suspension bushes, or exhaust manifolds. The lack of recurring faults suggests the vehicle has been maintained at a basic level, but the sparse record means critical components may not have been systematically checked beyond MOT thresholds. The mileage progression of approximately 6,446 miles per year aligns with typical usage for a vehicle of this age, with no abrupt spikes or prolonged periods of inactivity between tests. The gap between the February 2024 and November 2025 tests spans 17 months, covering 1,731 miles, which is consistent with standard MOT intervals. While this pattern indicates steady driving rather than neglect, it also means some components—such as brake pads, suspension bushes, or timing belt tensioners—may have operated beyond their optimal service intervals without professional intervention. A prospective buyer should prioritise a thorough inspection of the turbocharged diesel system, including boost pressure integrity and intercooler condition, given the mileage and age. The suspension should be assessed for worn or leaking bushes, particularly at the rear where binding or uneven wear is common in this model. Brake discs and calipers require close examination for lateral runout or excessive corrosion, as the last test did not specifically address these areas. Additionally, the MHEV hybrid system’s battery and high-voltage components should be checked for degradation, though no MOT history details these. Structural corrosion, especially around wheel arches and sills, warrants inspection, as diesel vehicles are prone to salt-induced deterioration.
