2024 Audi Q4 E-Tron S Line 45 Quattro Electric · SW74 ECC

The Q4 e‑tron’s electric drivetrain typically consumes around 20‑22 kWh per 100 miles, which translates to roughly £0.15‑£0.20 per mile at current electricity rates, making fuel costs considerably lower than comparable petrol models. Electric vehicles are exempt from road tax in the UK, so annual tax is £0, though the insurance group for a premium Audi EV usually falls in the 30‑35 range, leading to an annual premium of about £600‑£800 depending on driver profile.

Maintenance on electric cars is generally lower, with fewer moving parts and no oil changes. Expect routine checks such as tyre rotations, brake fluid replacement, and battery health monitoring, which together may average £150‑£250 per year. Adding fuel, tax, insurance and maintenance together gives an estimated annual running cost of roughly £800‑£1,200.

Inspect the high‑voltage battery pack for any signs of swelling, corrosion around terminals, or error codes on the vehicle’s diagnostic display. A healthy battery should show consistent range figures and no warning lights.

Check the charging port and cable for wear or damage, and verify that the vehicle can accept both AC and DC fast charging as advertised for the 45 Quattro variant. Also, examine the tyre tread depth and condition, as electric cars are heavier and can accelerate tyre wear.

Finally, review the electronic systems – infotainment screen, digital instrument cluster, and driver‑assist features – for any faults or software update notifications. While no MOT failures are recorded (none required yet), any advisory notes that appear during a future MOT should be taken seriously.
