Our Verdict
The Audi A3 S Line 40 TFSI e S-A is a se
Given that only one MOT test has been recorded for this vehicle, the test history provides limited insight into long-term mechanical patterns, so a thorough pre-purchase inspection is particularly important. The 40 TFSI e plug-in hybrid powertrain is more complex than a conventional petrol or diesel A3, so ensure the high-voltage battery, charging system and electric drive components are professionally assessed before committing. Check for any manufacturer recall notices relevant to the BX21 registration plate, as Audi has previously issued recalls affecting A3 model year 2021 vehicles. Negotiate based on the condition of the alloy wheels, tyres (a common MOT failure point for this model), and any wear to the interior trim that may indicate heavy use.
When viewing, request evidence of regular servicing from a recognised Audi centre or specialist, as the plug-in hybrid system requires specific maintenance schedules. Inspect the charging cable and port for damage, and ask whether the vehicle has been predominantly charged at home or via rapid chargers, as this affects battery longevity. Confirm the battery state of health if possible, as replacement can be costly. Given the modest MOT history, ask the seller to explain the gap in test records if any exist, and verify the mileage against the dashboard reading during a test drive.
The A3 40 TFSI e offers an official WLTP electric-only range of around 30 miles, which can significantly reduce fuel costs for drivers with regular short commutes and home charging capability. With CO2 emissions of around 30-40 g/km depending on equipment, it sits in a beneficial company car tax bracket and attracts reduced VED rates compared to conventional petrol variants, though plug-in hybrids no longer qualify for the same incentives they once did. Insurance is likely to fall within group 25-30 given the S Line trim and hybrid powertrain, so expect mid-to-upper tier premiums. Annual servicing costs at a main dealer typically range from £250-£400, with the additional hybrid system checks adding a modest premium. Brake wear tends to be lower on hybrids due to regenerative braking, but tyres can wear faster given the vehicle's torque output. Estimated annual running cost is £1,400-£1,800 depending on mileage and charging habits.
Begin with a close inspection of all four tyres, as tyres are the leading MOT failure reason across the A3 range according to aggregate data. Check tread depth, sidewall condition, and ensure matching brands or at least consistent sizes across axles — S Line models typically run on larger diameter alloys that can be expensive to replace. The second most common failure point is shock absorbers, so push down firmly on each corner and release, watching for the vehicle to settle smoothly without excessive bouncing. Listen for knocking noises over speed bumps, which may indicate worn suspension components.
For this specific plug-in hybrid variant, inspect the charging port for any signs of damage or corrosion, and verify the cable is present and functional. Check the driver's information display for any warning lights relating to the hybrid system, battery, or electric drive. The 1,395cc TFSI engine should start smoothly both in petrol-only and hybrid modes — a rough idle or reluctance to engage electric mode suggests underlying issues. Examine the rear of the vehicle for any tow bar or electrical connections that may indicate previous trailer use, which can stress the hybrid battery cooling system. Finally, inspect the underside for any signs of damage, particularly to the underfloor battery pack, and check that all electronic systems including climate control, infotainment and driver aids operate correctly.
This 2021 Audi A3 S Line 40 TFSI e S-A in black has covered 47,428 miles across approximately four years of use, equating to roughly 11,857 miles per year — slightly above the model average of 9,944 miles annually. The MOT history shows one recorded test in April 2025, which passed with no defects or advisories recorded. As a plug-in hybrid variant of the A3, it combines a 1,395cc petrol engine with electric propulsion and meets Euro 6 AP emissions standards. The vehicle sits within a model range where 87.6% of MOT tests pass at the first attempt, suggesting generally favourable mechanical outcomes.
The Audi A3 range shows a reasonable MOT pass rate of 87.6% across 11,585 vehicles analysed, with tyres and shock absorbers being the most common failure points. The plug-in hybrid variant has a more complex drivetrain than conventional A3s, which introduces additional potential service items beyond the typical mechanical components.
