2022 Mercedes-Benz E 220 Sport D Mhev Auto 1.9L Electric diesel · FT22 RYF

A pattern of brake wear concerns defines the roadworthiness picture for this 2022 Mercedes-Benz E 220, with the most recent DVSA test on 2 July 2026 recording a pass alongside a minor stone-chip defect on the front windscreen, and a prior pass on 13 April 2026 noting similar glazing damage. The more telling history sits behind those recent outcomes: a 7 May 2025 test produced both a pass advisory for thinning rear inner brake pads and a dangerous failure at the nearside front inner brake pad, where material had worn below the 1.5 mm minimum thickness. A dangerous category is the most severe classification an examiner can apply, signifying an immediate and significant risk to road safety, and the recurrence of inner pad wear across both axles within a single year points to either aggressive pad consumption or caliper-related issues that have not yet been addressed under test conditions. Against a typical annual accumulation of roughly 8,000 to 10,000 miles for a vehicle of this age and class, this E 220 has covered approximately 16,486 miles per year, placing it firmly in high-mileage territory for a four-year-old executive saloon. That rate of use places elevated demand on braking consumables, tyres, suspension bushes, and drivetrain components such as the dual-clutch automatic gearbox and the mild-hybrid electrical ancillaries. The MOT record shows three tests within roughly fifteen months with no extended gaps in testing, which confirms the vehicle has remained in continuous service rather than laid up, so corrosion risks associated with long-standing cars are less of a concern here, but wear-related degradation is the primary mechanical theme to investigate. For any prospective buyer, the brake system should be the first item scrutinised during a physical inspection and test drive. Lift the wheels and check the remaining friction material thickness on all four corners, paying particular attention to the inner pads which the MOT history has flagged twice, and inspect the front brake discs for lipping or scoring, as inner pad wear of that severity often correlates with glazed or worn disc surfaces. On the road, listen for any grinding or squealing under light braking, watch for pulling to one side which could indicate a binding caliper, and test for a spongy or low pedal that might suggest a hydraulic issue or a seized caliper slider following the pad replacement. Beyond the brakes, the high annual mileage warrants close attention to the suspension geometry and tyres. Check the front and rear coil springs for any signs of sagging or corrosion, particularly given Mercedes' known susceptibility to spring fracture on earlier E-Class generations, and inspect the control arm bushes and drop links for play by rocking the wheels at full lock. Tyre tread depth and even wear across the axle are important indicators of alignment and suspension health; uneven inner or outer wear could point to worn bushes or tracking issues. The test drive should include a section of rough urban road surface to expose any knocking from anti-roll bar links or top mounts, a motorway stretch to detect vibration through the steering wheel which may indicate tyre balance or front suspension wear, and firm braking from higher speeds to confirm straight-line stability and ABS intervention feel. Given the diesel mild-hybrid powertrain has been worked hard, a diagnostic scan for stored Mercedes M-BENZ-related fault codes, particularly around the 48V mild-hybrid system and the 9G-Tronic transmission, would be a prudent final check before purchase.
