2025 Audi A5 S Line Tfsi S-A 2.0L Petrol · LR75 AAU

The 2.0 TFSI petrol engine in this generation of A5 typically returns around 38-45 mpg in real-world driving, depending on conditions and driving style, with combined WLTP figures closer to 42 mpg. Road tax for a Euro 6EA petrol vehicle registered from 2025 sits in the lowest band, costing approximately £190 per year. Insurance for an Audi A5 S Line TFSI typically falls within groups 30-38, so expect premiums in the £600-£900 range for a typical driver. Maintenance costs for a modern Audi are moderate but parts and labour at main dealers can be expensive. Routine services alternate between basic and major, with costs of approximately £300-£500 at independent specialists or £400-£700 at Audi dealers. The S tronic automatic gearbox requires periodic oil changes, typically every 40,000 miles, at a cost of around £250-£400. Given the vehicle's youth, major wear items such as brakes, fluid changes, and tyres are unlikely to be due imminently. Overall annual running costs including fuel, tax, insurance, and maintenance should be in the region of £2,200-£2,800 for a typical driver covering around 10,000 miles per year. This is broadly comparable to rivals such as the BMW 4 Series and Mercedes-Benz C-Class Coupe.

Given the absence of MOT history due to the vehicle's age, traditional MOT-related inspections are not yet relevant. However, buyers should conduct a thorough pre-purchase inspection focusing on build quality, panel alignment, and paint condition, as early-build examples occasionally exhibit minor fit and finish issues. Check all body panels for consistent gaps and ensure the white paintwork has no stone chips, particularly on the bonnet, front bumper, and wheel arches. For the 2.0 TFSI engine, listen for any unusual noises on cold start and check for any signs of oil leaks around the sump and cam chain area, which has been a known concern on earlier TFSI units. The S tronic automatic should engage smoothly across all gears without any juddering or hesitation, and manual mode should respond promptly to paddle inputs. Verify the engine oil level and condition on the dipstick, and inspect the coolant reservoir for any discolouration. Inspect the interior for any signs of excessive wear on high-contact areas such as the steering wheel, gear selector, and seat bolsters, which can indicate higher mileage than stated or previous use as a demonstrator. Check all electronic systems function correctly, including the infotainment screen, climate control, parking sensors, and reversing camera, as repairs to these systems can be costly. Finally, verify the tyre condition and brand, ensuring they are premium manufacturers with adequate tread depth.
