2024 Mercedes-Benz AMG A 45 S 4MATIC+ Plus Auto Petrol · RE03 ART

No MOT test result has been recorded for this 2024 Mercedes-Benz AMG A 45 S 4MATIC+ Plus automatic, which is consistent with the vehicle being under three years of age from the current date of 2026-09-02 and therefore not yet subject to compulsory DVSA roadworthiness testing. Because there is no prior MOT data to examine, it is not possible to evaluate a maintenance trend, identify recurring advisories, or pinpoint any deterioration in safety-critical components such as brakes, tyres, suspension, or emissions output. Any prospective buyer must therefore rely entirely on the physical condition of the vehicle, its documented service history from an authorised Mercedes-Benz or specialist performance outlet, and an independent pre-purchase inspection rather than on MOT pass or fail evidence. Mileage context is also absent from the records supplied, and with no MOT test points against which to verify odometer readings, it is not possible to cross-check the displayed mileage for consistency or to estimate an annual usage rate. Given that this is a high-performance 2.0-litre turbocharged hot hatch with an AMG-specific drivetrain and 4MATIC+ all-wheel-drive system, any significant deviation from a typical mileage of between 6,000 and 12,000 miles per annum warrants closer scrutiny. Very low annual mileage can promote standing corrosion on the brake discs, binding or seized caliper pistons due to infrequent use, and premature degradation of the 12V battery and engine oil through short journeys that prevent the unit from reaching full operating temperature. Conversely, disproportionately high mileage would place greater demand on the dual-clutch automatic transmission, the turbocharger, the all-wheel-drive transfer case, and the multi-link rear suspension, all of which are expensive to rectify on an AMG-badged vehicle. Because the MOT file is clean and sparse, the buyer should adopt a methodical physical inspection tailored to the vehicle's age and performance specification. Externally, examine all four tyres for both tread depth, which must legally be a minimum of 1.6 mm across the central three-quarters of the tread, and for sidewall cracking or perishing caused by age rather than wear, as performance tyres on lightly driven cars frequently suffer rubber degradation before the tread is exhausted. Inspect the brake discs for lipping, scoring, or surface rust that has not been cleaned off through normal use, and verify that the calipers release cleanly without the pads remaining in contact with the disc. Under the bonnet, check the condition and age of the 12V battery, as AMG electrical systems place considerable load on the unit and a battery older than four years may be nearing the end of its service life. Inspect all coolant, brake fluid, and engine oil lines for signs of leakage, particularly around the turbocharger oil return pipe and the intercooler pipework, which are known stress points on the M139 powerplant. A test drive should replicate the conditions under which this vehicle is likely to have been used, with careful attention paid to the performance of the dual-clutch transmission during low-speed manoeuvres and parking, where these units can exhibit juddering or hesitant engagement if the clutch pack or mechatronics unit has been subjected to excessive thermal loading. Listen for any clonks or knocking from the multi-link rear suspension, the front MacPherson struts, and the anti-roll bar bushes, as AMG-tuned dampers and bushes are subjected to high loads and may show premature wear. Confirm that the 4MATIC+ system engages smoothly without warning lights on the instrument cluster and that the launch control and driver-selectable drive modes function as intended. Finally, verify that the vehicle has been serviced strictly in accordance with Mercedes-Benz Assyst intervals, that the digital service history is fully up to date, and that any remaining manufacturer warranty is still in force, as this provides significant financial protection against the costly mechanical failures that can affect a hand-built AMG engine and drivetrain.
