2021 Audi A4 S Line 40 Tfsi Mhev S-A 2.0L Hybrid electric (clean) · LP21 PSO

This Audi A4 S Line demonstrates a stable roadworthiness pattern over the past two MOT cycles, with both tests in June 2024 and July 2025 resulting in clean passes at 20,192 and 28,980 miles respectively. The absence of defects or advisories in either test suggests the vehicle has not experienced any recurring mechanical failures or structural concerns during this period. However, the July 2025 test occurred just 12 months ago, which is within the standard MOT validity window, though slightly earlier than the typical 12-month interval. This indicates the vehicle remains compliant with current UK roadworthiness standards, though a thorough inspection will be necessary to confirm no deferred or hidden issues have developed since the last test. The recorded mileage of 28,980 miles over five years—approximately 5,800 miles annually—falls well below the average for a vehicle of this age and specification. Such low mileage could imply limited use, extended periods of storage, or potentially inconsistent ownership. The gap between the 2024 and 2025 tests reflects a steady accumulation of around 8,788 miles in 12 months, which aligns with the overall low-mileage trend. While this reduces wear on high-stress components like suspension bushes and brake calipers, it may also suggest inconsistent maintenance intervals, particularly for fluid changes or minor servicing that could have been deferred. Given the lack of recorded defects, the primary focus for an in-person inspection should centre on components that often fail without overt warning signs. The MOT history does not reveal any advisories, but the hybrid-electric nature of the MHEV system means the high-voltage battery and associated wiring should be checked for corrosion or degraded insulation. The suspension—particularly the coil springs and bushes—should be examined for uneven wear or binding, as these are common points of failure in vehicles with low mileage but extended periods of inactivity. Brake discs and calipers, while not flagged in the MOT, warrant scrutiny for uneven wear or binding, especially if the vehicle has been stored for prolonged periods. Additionally, the exhaust system should be inspected for leaks or corrosion, particularly around flanges and joints, as these can develop silently over time. Finally, the underbody and wheel arches should be assessed for signs of rust or structural compromise, which may not have been detected in the MOT but could compromise the vehicle’s integrity.
