2024 Audi Q4 E-Tron S Line 40 Electric · RE24 FSU

As a fully electric vehicle, the Q4 e-tron S Line 40 sits in the £0 road tax bracket (VED exempt) and is also exempt from the London Congestion Charge and most Clean Air Zone charges, which is a meaningful saving for urban drivers. Insurance-wise, expect to be placed in group 38-40 depending on trim, so premiums will be higher than average — typically £600-£900 annually for a 40-year-old main driver. The official WLTP range is around 310-320 miles for the 40 variant with the 77 kWh battery, translating to real-world efficiency of 3.0-3.5 miles per kWh and an annual electricity cost of roughly £500-£700 if covering 9,000-10,000 miles.

Servicing for the Q4 e-tron is required every two years or 20,000 miles, with prices typically £250-£400 per visit depending on whether you use a main dealer or independent specialist. Brake fluid should be changed every two years regardless of mileage, and the cabin filter annually. Because the vehicle uses regenerative braking, brake pads and discs last significantly longer than on a combustion car, but the S Line's larger wheels can accelerate tyre wear. Overall, the running costs are competitive with premium EVs but cheaper than petrol or diesel alternatives in the same segment when considering fuel and tax savings.

Given that MOT records cannot establish this vehicle's mechanical condition due to its age, a physical inspection and diagnostic check are essential. Begin with the high-voltage battery: request a state-of-health report from an Audi dealer or specialist, which should show at least 90% capacity retention given the vehicle's age and mileage. Check the underside of the car for any damage from speed humps, which is common on the Q4 e-tron given its limited ground clearance, and inspect the plastic undertray for cracks or missing fasteners.

Examine the charging port door and surrounding paintwork for scratches, which suggests frequent public charging. Inspect all four wheels for kerbing damage — the S Line trim's larger alloys are particularly vulnerable — and check the tyres for even wear patterns. Verify that the matrix LED headlights function correctly across all modes, as lighting system failures are among the most common MOT failure points for the model in aggregate, though this car has not yet been tested.

Inside, test the MMI touchscreen and haptic climate controls thoroughly, as software glitches have been reported on early examples. Confirm that all driver-assistance systems, including adaptive cruise control and lane-keeping assist, calibrate and operate as expected. Finally, check for water ingress in the boot and footwells, which has been an occasional issue with the Q4 e-tron's tailgate seals.
