2024 Audi S4 Vorsprung TDI Mhev Quat A Diesel · SG24 AAP

The vehicle has no recorded MOT history, so there is no recent test outcome to reference and consequently no trend—stable, worsening or improving—to evaluate. Without any official pass or fail data the buyer should treat the car as needing a fresh MOT as soon as possible to confirm its roadworthiness and to obtain a baseline of any current defects. Mileage is not supplied, and the car is a 2024 model, making it roughly two years old. In the absence of a kilometre reading the typical annual usage for a performance sedan such as an Audi S4 would be in the region of 8‑12,000 miles per year, giving an expected total of about 16‑24,000 miles. If the actual mileage is significantly lower, the engine, turbocharger and MHEV high‑voltage system may have experienced limited wear but could be susceptible to age‑related degradation of seals and rubber components. Conversely, if the odometer is high the buyer should be alert to accelerated wear on the clutch, turbo bearings, suspension bushings and brake discs, and to the possibility of reduced remaining service life on major wear items. Given the lack of MOT data and the vehicle’s age, a thorough visual and tactile inspection is essential. Check the tyre sidewalls for cracking, dry rot or age‑related hardening and verify that tread depth is at least 1.6 mm and evenly worn across the tread width. Examine the under‑body for corrosion on the wheel arches, chassis rails and exhaust system, paying particular attention to any rust around the turbo inlet and exhaust manifold. Inspect the 12‑volt battery for electrolyte level, terminal corrosion and cranking performance, and, if accessible, confirm the health of the high‑voltage hybrid battery with a diagnostic read‑out. Look for any oil or coolant leaks around the valve cover gaskets, oil cooler and intercooler piping, and ensure that the exhaust system is free of cracks or perforations that could affect emissions compliance. Mechanically, the buyer should verify the condition of the front suspension – coil springs, damper mounts and anti‑roll bar links – for any signs of sag, leakage or excessive play, and confirm that the steering rack and tie‑rod ends operate smoothly without clunking. Inspect the brake discs for surface rust, scoring or uneven wear and ensure the pads are within thickness limits; check that the calipers move freely and are not binding. Examine all fluid reservoirs: engine oil should be clear and at the correct level, brake fluid should be free of moisture (ideally replaced every two years), coolant should be the proper colour and free of debris, and the DSG or manual transmission fluid should be at the correct level and not discoloured. A full diagnostic scan is advisable to clear any stored fault codes, particularly for the DPF, turbocharger and hybrid system, and to confirm that the timing chain tensioner and oil pump are operating correctly. During a test drive listen for any abnormal turbo whine, clutch judder, or front‑end clunks, watch for warning lights, and feel for any pull or vibration that could indicate suspension or drivetrain issues. Securing a current MOT and a comprehensive service history before finalising the purchase is strongly recommended.
