2012 Mercedes-Benz E 2.1L Diesel · AS11 AGG

A history of intermittent mechanical issues, including a dangerous failure for a fractured wheel rim and advisories regarding brake wear, defines this vehicle's recent MOT profile. While the most recent test on 5 December 2025 resulted in a pass with no defects recorded, the record shows a fluctuating level of roadworthiness over the last few years. The transition from a dangerous failure in October 2021 to a clean pass in late 2025 suggests that specific component failures have been addressed, though the 2024 advisory regarding worn brake discs indicates that consumable components are reaching the end of their service life. The vehicle has covered 125,331 miles over its approximately 14-year lifespan, which equates to an average annual usage of roughly 8,952 miles. This mileage accumulation is consistent with typical long-distance or mixed-use patterns for a vehicle of this age. Mechanically, this level of usage suggests that while the vehicle has not been subject to extreme high-mileage wear, components such as suspension bushes, dampers, and drivetrain mounts will have undergone significant cycles of stress. The relatively steady mileage progression reduces the likelihood of issues stemming from long periods of stationary use, such as seized calipers or perished rubber seals. Prospective buyers should pay close attention to the braking system during a test drive, specifically addressing the advisory for worn brake discs noted in October 2024. Although the 2025 test showed no defects, the previous warning regarding all four discs suggests the system may be approaching a replacement interval. Listen for any rhythmic pulsing through the brake pedal or vibrations in the steering wheel when decelerating from higher speeds, which can indicate disc thickness variations or warping. Additionally, check for any residual brake noise or grinding sounds that might suggest the pads are nearing the limit of the worn discs. Given the 2021 failure involving a fractured inner edge on the offside rear road wheel, it is prudent to perform a close visual inspection of all four alloy wheels for any signs of structural cracking, heavy kerbing, or impact damage. During the test drive, pay close attention to the rear of the vehicle for any lateral movement or knocking sounds when traversing uneven surfaces or speed bumps, which could indicate issues with the wheel hub or suspension components related to previous impact stresses. Ensure the steering feels precise and free from any pulling to one side, which would confirm that the wheel and suspension geometry remain within acceptable parameters.
