2019 Mercedes-Benz E 220 AMG LNE NGT ED PRM + D A 1.9L Diesel · BU69 FMP

The defining mechanical story of this E 220 d revolves around a brake system that has clearly reached the back end of its service life, with a sharp deterioration appearing at the most recent test. The 2024 and 2025 examinations returned completely clean passes with no advisories, suggesting the discs and pads were either renewed or still well within tolerance at that point. The 2026 test cycle, however, exposed significant wear on both the front and rear brake discs, with lipping and pitting recorded on both sides at each axle. The first attempt on 12 August 2026 failed outright on a dangerous front tyre defect with cord exposure across the entire circumference, a failure that points to running on severely aged or damaged Run-Flat rubber rather than a single impact. A clean pass followed the next day once new tyres were fitted, but the brake disc advisories carried over unchanged, leaving the braking hardware as the single most pressing wear item on this vehicle. With 100,661 miles recorded over roughly seven years, this Mercedes has covered about 14,380 miles per year on average, which is comfortably above typical private-car usage and sits in the upper bracket for a premium executive saloon of this age. The mileage progression between tests has been steady and consistent rather than spiking or stalling, with no extended gaps that might indicate a long period off the road. Mechanically, that sustained annual accumulation translates into a drivetrain, transmission and underbody that have absorbed genuine working life rather than gentle weekend use. The OM654 diesel engine and 9G-Tronic automatic combination is generally robust, but at this mileage the turbocharger, injectors, dual-mass flywheel, EGR cooler and AdBlue system components are all approaching the sort of mileage where preventative inspection rather than reactive repair becomes sensible. High annual mileage also brings forward the replacement cycle for suspension components, meaning bushes, control arms and damper mounts are likely closer to needing attention than the MOT record alone might suggest. For a prospective buyer, the brake discs and pads should be the first negotiating point, as the advisory wording describes lipping and pitting that will only deepen with further use and could easily tip into a failed condition before the next test. On a road test, listen for any rotational graunching or vibration through the brake pedal under firm stops from higher speed, as pitted discs often present as pedal judder or a pulsing sensation rather than a major loss of stopping power. Inspect the tyre fitment directly, confirming all four corners are matching 245/35 R20 Run-Flat items from a reputable manufacturer with healthy tread depth, since the dangerous failure suggests the previous tyres had been left in service well beyond their safe life. Given the mileage, a thorough check of the suspension is warranted even though nothing has been flagged officially: push down firmly at each corner and release to feel for excessive bouncing, and listen for clonks or creaks from the front lower wishbones, anti-roll bar drop links and rear trailing arm bushes as the weight settles over speed humps and uneven surfaces. Underneath, the buyer should pay close attention to corrosion on the subframe, brake lines and suspension arms, as six-figure-mileage executive cars can begin to show surface oxidation in the wheel arches and along the undertray even when the bodywork appears clean. With the engine running from cold, listen for any rough idle, misfire or diesel knock, and check for oil seepage around the rocker cover, turbo oil feed pipes and oil filter housing, all common areas on higher-mileage OM654 units. On the move, confirm the 9G-Tronic changes smoothly through all ratios without flare between gears, particularly under light throttle around 30 to 50 mph where wear in the mechatronic unit or torque converter can first appear. Finally, verify that the AdBlue system is functioning correctly with no dashboard warnings, as emissions-related repairs on these systems can be disproportionately expensive relative to the underlying mechanical wear on a car of this age and mileage.
