2014 Mercedes-Benz E 2.1L Diesel · WN64 AEU

Structural tyre failures and recurring service brake binding define the mechanical history of this twelve-year-old Mercedes-Benz, which successfully navigated an MOT test on 2026-01-23 after rectifying two dangerous structural tyre tears. While the vehicle holds a pass certificate for its latest test, the ongoing advisory regarding an offside rear service brake binding points to a component that requires immediate mechanical attention. This follows a previous failure in 2021 driven by a dangerous inner wall tyre bulge and a malfunctioning tyre pressure monitoring system, demonstrating a recurring pattern of major safety-related component issues throughout its testing life rather than a consistently stable roadworthiness record. Accumulating a total of 95,969 miles over its lifetime equates to an average of roughly 7,997 miles per year, representing typical usage patterns for an executive saloon of this age. This steady annual mileage accrual means standard wear and tear will be distributed evenly across the drivetrain, suspension, and braking architecture without the added complications associated with prolonged periods of standing or extreme high-mileage fleet use. Testing intervals have remained regular throughout its history, confirming that the car has been presented annually for statutory roadworthiness checks. During a physical inspection and test drive, the prospective buyer must closely examine the braking system to address the persistent advisories. Listen carefully for any scraping, grinding, or squealing noises from the rear wheels which indicate that the offside rear caliper is dragging or the parking brake mechanism requires adjustment, and check the alloy wheels immediately after a test drive for excessive heat radiating from the hubs. The front brake pads were also noted as wearing thin during the 2025 test, meaning both front discs and pads should be inspected for remaining friction material thickness and scoring. Given the history of structural tyre defects, including dangerous tears and bulges on both front and rear axles across multiple tests, inspect the inner and outer sidewalls of all fitted tyres for any signs of cracking, perishing, or bulging. On the test drive, pay attention to any steering wheel vibrations or pulls that could point to wheel alignment issues or uneven tyre wear, and verify that the tyre pressure monitoring system operates correctly without dashboard warning lights, given its previous failure record.
