2021 Mercedes-Benz AMG A 35 Premium + 4MATIC ED A 2.0L Petrol · CU71 HGD

A clean two-test run of pass results, including the most recent examination on 28 April 2026 with no advisories recorded, sits against a single earlier failure on 28 August 2024 where a nearside front inner constant velocity joint boot was found split and no longer preventing ingress of dirt. This was classified as a Major defect at the time, meaning the vehicle would not have been legal to drive until repaired, and it is worth confirming documentary evidence that the driveshaft or full shaft assembly was replaced rather than just a boot re-packed, as a contaminated CV joint typically requires renewal. The accompanying advisory from the same date regarding front brake pads wearing thin on both sides was repeated as an advisory on the subsequent pass of 9 September 2024, indicating the pads were monitored rather than replaced at that test. No further brake, drivetrain or suspension items have appeared on the record since, leaving the 2024 failure as the only flagged mechanical event across five years of testing. Annual mileage is recorded at approximately 9,791 miles per year over the five-year span, which sits within typical usage parameters for a modern performance hatchback. The accumulation is steady across the recorded tests with no obvious gaps that would suggest a long period off the road, and no unusual mileage jumps between examinations that might indicate a discrepancy. At this rate, consumables such as tyres, brake pads and discs, and the dual-clutch transmission service intervals should follow predictable wear patterns, and the drivetrain will have seen regular but not excessive use. Given the CV joint failure recorded in 2024, particular attention should be paid during a test drive to any clicking or knocking from the front end, especially when turning at low speed, which would indicate a worn joint rather than a degraded boot alone. Listen for any shudder or vibration under acceleration, as a contaminated CV joint can present symptoms well after the visual boot damage is repaired. Inspect the inner and outer CV boots on both front corners for fresh grease deposits, perishing or cracking, and check that any replacement gaiter shows a uniform factory-style fit rather than a clamped aftermarket repair. The brake advisory history from late 2024 indicates front pads were approaching the minimum thickness at that point, so it is prudent to confirm the current pad material depth via the wheel spokes and to inspect the front discs for lipping, scoring or blueing from heat. Under braking, the pedal should feel firm without excessive travel, and there should be no pulling to either side that might suggest a binding caliper following a pad change. Beyond the flagged items, the suspension on this model uses multi-link rear geometry and MacPherson front struts, so listen for clonks or creaks over uneven surfaces which could point to worn anti-roll bar drop links or top mount bearings, and verify that all four tyres are matching in brand, size and tread depth to ensure the 4MATIC system is not being subjected to uneven traction inputs.
