2020 Mercedes-Benz CLA 220 AMG Line Premium + D A 1.9L Diesel · KV20 PFD

The 2020 Mercedes-Benz CLA 220 AMG Line Premium+ D A presents a stable but watchful maintenance trend. The most recent MOT, conducted on 17 March 2026 at 55,880 miles, resulted in a pass, though the tester flagged a fluid leak and an AdBlue injector or pipe slightly leaking under item 8.4.1 (a) (i). This is a minor advisory rather than a failure, yet it signals a developing issue with the selective catalytic reduction system that a buyer must verify has been rectified before the next test. The vehicle has never failed an MOT, and the overall record suggests a car that has been kept in generally roadworthy condition. The mileage accumulation is unremarkable for a six-year-old vehicle. From the first recorded test on 3 March 2023 at 5,186 miles through to the latest at 55,880 miles, the car has covered roughly 50,694 miles in just over three years, averaging around 16,900 miles annually during that period. However, the gap between the March 2023 and February 2024 tests shows only 2,112 miles added in nearly twelve months, followed by a jump of 2,574 miles to February 2025, then a dramatic leap of 46,008 miles between February 2025 and March 2026. That final year's mileage spike is significant and points to sustained high-speed or long-distance driving, which places accelerated consumable wear on brake discs, pads, tyres, suspension bushes, and drivetrain mounts. The recurring advisory pattern is clear. Both front tyres were flagged for cracking or perishing in February 2024 at 7,298 miles and again in February 2025 at 9,872 miles, both times on the same 225/45R18 fitment. This repeated appearance across two consecutive tests suggests the previous owner did not replace the tyres despite the advisory, a pattern that indicates basic preventative upkeep was deferred. A buyer should inspect the current tyres carefully, checking the date codes, sidewall condition, and tread depth, and budget for replacement if the originals or a similarly aged set remain fitted. Beyond the tyres, the AdBlue system leak from the March 2026 test warrants close attention. A leaking injector or pipe can lead to crystallised deposits around the exhaust treatment system, potentially causing costly blockages or NOx sensor faults if left unresolved. Given the high-mileage year just completed, a prospective buyer should also examine the condition of the front brake discs and pads, check for play in suspension track rod ends and wishbone bushes, and inspect the underside for any corrosion or fluid weeping from the power steering rack or gearbox. The MOT record is clean on structural and mechanical failures, but the pattern of ignored advisories means a thorough independent inspection is strongly recommended.
