2026 Mercedes-Benz AMG A 35 Premium + Mhev 4M A 2.0L Hybrid electric · ST54 RAY

The most recent DVSA MOT test for this 2026 Mercedes-Benz AMG A 35 Premium MHEV 4Matic was conducted on 14 May 2025, resulting in a pass with no advisories or defects recorded. The vehicle also passed without comment at its earlier test on 3 June 2024. There is one recorded failure on 28 May 2024, but notably no defects are listed against that entry, which suggests either a failure on items not formally recorded within the standard advisory/defect categories or a test that was subsequently recorded as passed on the very next inspection. With two clean passes and no advisory items logged across the recorded tests, the maintenance trajectory presented by the MOT history is stable and unremarkable, offering no direct DVSA evidence of neglect, wear concerns, or developing mechanical faults. With a recorded mileage of 35,271 miles on what is effectively a near-new performance vehicle, it is too early in the vehicle's service life to draw meaningful conclusions from annual mileage averages. However, even at this early stage, 35,271 miles equates to a substantial usage figure for a car of this age, which indicates the vehicle has likely been driven regularly rather than left standing for prolonged periods. Regular use of an MHEV powertrain is generally beneficial for component longevity, as it keeps seals lubricated, the 48-volt mild hybrid system active, and the brake discs freed from standing corrosion. That said, consistent higher-mileage driving places greater demand on consumables such as tyres, brake pads and discs, and the higher-output 2.0-litre turbocharged engine and its associated ancillaries. A prospective buyer should ensure that the recorded mileage is supported by a full Mercedes-Benz main agent or specialist service history, ideally with digital records, given the relative complexity of the mild hybrid electrical architecture. Given the clean DVSA record and the absence of any advisories, there is no specific defect pattern to investigate from the MOT data alone. Instead, physical inspection should focus on the age- and usage-related factors relevant to a performance MHEV of this profile. The 12-volt and 48-volt battery systems should be interrogated using a diagnostic tool capable of reading Mercedes-Benz modules, as state of health data for both battery packs will confirm whether either is showing early degradation, a known concern on MHEV vehicles even at modest mileages. The tyres, likely high-performance fitments, should be inspected closely for uneven shoulder wear indicative of alignment geometry issues, particularly negative camber wear from the sporty factory setup, and for any sidewall perishing given that high-performance rubber compounds can harden with age even when tread depth remains adequate. Brake discs and pads, particularly on the front axle given the AMG performance specification, should be measured for remaining material and inspected for lipping or hot spots, while a thorough undertray inspection for any signs of fluid leakage from the MHEV electrical components, turbocharger oil feed lines, or the rear differential is advisable. On a test drive, particular attention should be paid to the behaviour of the dual-clutch transmission, ensuring smooth engagement at low speed and clean, prompt shifts under load without any shunt or hesitation. Listen carefully for any suspension clonks or knocks over uneven surfaces, as the A 35 uses a sophisticated multi-link rear suspension arrangement whose bushes and anti-roll bar links can be costly to replace if worn. The steering should remain precise and free of vibration at speed, and the all-wheel-drive system should apportion torque seamlessly without any binding sensation during tight low-speed manoeuvres. Pay close attention to any warning messages on the instrument cluster, particularly relating to the mild hybrid system, battery, or driver assistance systems, as these are commonly flagged only after a fault has been logged electronically. Finally, verify the operation of the cabin comfort and infotainment systems, and confirm that the vehicle history file includes the original charging cable and both key fobs, as replacements for the current Mercedes-Benz key systems are notably expensive.
