2012 Mercedes-Benz E 2.1L Diesel · LG51 ACK

Persistent suspension and brake system degradation defines the mechanical history of this vehicle, which passed its most recent MOT on 5 May 2026 despite a collection of recurring advisories. The record reveals a pattern of escalating component wear, particularly concerning the suspension arm bushes and brake pipe integrity, which have been flagged repeatedly over the last three years. While the vehicle has successfully cleared its annual inspections since the 2024 failure, the persistence of these advisories suggests that the underlying structural and linkage components are reaching the end of their service life and will likely require proactive replacement rather than further monitoring. With 136,701 miles accumulated over approximately 14 years, the vehicle has seen consistent usage averaging nearly 10,000 miles per annum. This steady accumulation indicates that the car has remained in regular operation throughout its life, avoiding the mechanical complications often associated with long-term storage or extended periods of inactivity. However, this high-mileage profile necessitates a thorough inspection of high-wear drivetrain and chassis components, as the cumulative stress on suspension geometry and hydraulic lines is consistent with its age and distance covered. Prospective buyers should prioritise a physical inspection of the suspension arm bushes, as the nearside and offside rear units were specifically noted as worn during the latest test. During a test drive, listen closely for knocking or clunking noises when traversing uneven road surfaces or speed bumps, which often indicate excessive play in these linkages. Furthermore, the light oil misting on the offside front shock absorber warrants close scrutiny; look for signs of fluid weeping down the strut body, as this can lead to uneven tyre wear and compromised handling stability. The reported oil leak, while not currently excessive, should be investigated to determine its source, as it may be originating from the engine or transmission seals. The history of brake pipe corrosion, which resulted in multiple major failures in 2024, requires careful attention. Although the pipes were addressed to meet pass standards, the recurring nature of these advisories suggests that the vehicle may have been exposed to environments conducive to corrosion. Verify the condition of all visible brake lines for signs of pitting or surface rust during a pre-purchase inspection. Additionally, check the tread depth and wear patterns on all four tyres, specifically the nearside rear, as the tendency for the vehicle to exhibit uneven tyre wear has been a consistent feature across multiple MOT cycles. Any steering pull or vibration felt through the steering wheel during braking should be treated as a potential indicator of further suspension or braking system fatigue.
