2022 Volkswagen Arteon R TSI 4MOTION S-A 2.0L Petrol · KN72 LSD

The vehicle's most recent MOT history shows a pass on 29 October 2025, following an initial failure on the same date. The failure was recorded as a major defect due to the exhaust lambda reading falling outside the specified limits during a fast idle test. This indicates an issue with the engine's air-fuel mixture or the oxygen sensor's ability to accurately monitor exhaust gases. As the vehicle passed immediately following this failure, the fault was clearly addressed, suggesting the maintenance trend is currently stable, though the previous emissions failure warrants a cautious review of the sensor and fuel system integrity. With a recorded mileage of 14,066 miles over approximately four years, this Arteon has been driven significantly less than the UK average, averaging roughly 3,516 miles per annum. While low mileage generally implies reduced wear on the 4Motion all-wheel-drive system, suspension bushes, and brake pads, it also suggests the vehicle may have experienced long periods of inactivity or very short, low-temperature journeys. Such usage profiles can lead to specific mechanical concerns, such as carbon accumulation in the engine or moisture retention in the exhaust and lubrication systems, which may have contributed to the recent lambda reading failure. During your inspection, you should pay close attention to the health of consumables that degrade with age rather than distance. Examine the tyre sidewalls for any signs of perishing or cracking, as low-use vehicles often have sufficient tread but rubber that has hardened due to age. Check the brake discs for surface corrosion or pitting and listen for any binding or squealing from the calipers, which can occur when a car sits for extended periods. It is also vital to verify the service history to ensure that oil and fluid changes have been performed on a calendar basis rather than purely based on mileage, as oil and coolant can degrade over time regardless of distance driven. Furthermore, given the low annual mileage, the 12V battery may have undergone significant discharge cycles; testing the battery health is essential to avoid electronic faults. On the test drive, monitor the engine's idle stability and listen for any hesitation or stumbling, which could indicate lingering issues with the fuel trim or oxygen sensors related to the previous MOT failure. Finally, check for any signs of fluid leaks around the engine bay and ensure the cooling system is pressurized and free of leaks, as time-based degradation can affect seals and hoses even in low-mileage vehicles.
