2021 Audi A6 S LN Blck ED 40 TDI Mhev SA 2.0L Diesel · LF71 FBE

The most recent MOT test on 2026-08-07 resulted in a passing outcome, marking a return to full roadworthiness after a previous failure in the same test cycle on the same date. This pattern suggests a stable maintenance trend, with no evidence of worsening mechanical issues or recurring systemic failures. The prior failure—specifically the non-functioning near-side rear stop lamp—was isolated to a single component, indicating a straightforward electrical or wiring concern rather than a broader fault. While the advisory from the 2024 test remains, it pertains to minor tyres with nails and a near-side child seat obstructing inspection, neither of which directly impacts structural or safety-critical systems. The vehicle’s MOT history thus far reflects responsible upkeep, with no critical defects or repeated advisories warranting immediate concern. The recorded mileage of 49,913 miles for a 2021 Audi A6 TDI represents a moderate annual usage rate of approximately 9,983 miles per year, which is within the expected range for this vehicle’s age and powertrain type. Such mileage accumulation is consistent with typical driving patterns, though it does not preclude potential wear on consumables like brake pads, suspension components, or fluid systems. The absence of significant mileage gaps suggests the vehicle has been in regular use, which may accelerate wear on high-mileage items such as the drivetrain, exhaust system, or electrical harnesses. However, the TDI’s hybrid-electric powertrain and modern engineering mitigate some of the wear risks associated with conventional diesel engines, though the buyer should remain vigilant for signs of fluid degradation or electrical component fatigue over time. To proceed with a thorough inspection, the prospective buyer should prioritise checks on the electrical system, particularly the stop lamp circuit, given the prior MOT failure. Test-drive symptoms to watch for include a flickering or intermittent rear stop lamp, particularly when braking or engaging reverse gear, which may indicate a failing bulb, wiring issue, or relay failure. The near-side rear tyre nails are non-critical but could indicate underlying tyre damage or improper inflation, so a visual inspection of the tyre tread and sidewall for cracks or bulges is advisable. Additionally, the child seat advisory suggests the vehicle may have been fitted with a rear-facing seat, which could obscure inspection of the rear wheel and brake system—ensure the seat is removed for a full MOT-style inspection before purchase. Beyond the MOT history, the buyer should conduct a comprehensive physical inspection tailored to the vehicle’s age and mileage. Given the TDI’s hybrid-electric configuration, the 12V battery and starter motor should be tested for responsiveness, as these components are critical for the powertrain’s hybrid function. Check for signs of corrosion around the battery terminals and undercarriage, particularly in the exhaust system and wheel arches, where condensation and road debris can accelerate rust. The suspension should be inspected for uneven tyre wear, which may indicate worn coil springs, damaged suspension bushes, or binding control arms. Listen for clunking noises during cornering or over bumps, which could signal worn or broken suspension components. Fluid levels—particularly the brake fluid, coolant, and differential oil—should be checked for degradation or contamination, with a recommendation for a full fluid service every 60,000 to 80,000 miles or as per the service book. Finally, the tyre sidewalls should be examined for signs of perishing or cracking, which can weaken the tyre structure over time, even at moderate mileages. A thorough service history review, including oil changes and fluid servicing, would further validate the vehicle’s maintenance record.
