2014 Mercedes-Benz E 2.1L Diesel · AF14 OKC

A recurring pattern of brake, suspension and undertright advisories dominates the MOT history of this 2014 Mercedes-Benz E-Class, painting a picture of a chassis that has been working hard but receiving only partial remedial attention. The most recent test on 8 October 2025 returned a pass, yet it carried forward exactly the same cluster of advisories that had been flagged on the failed re-test just twelve days earlier on 26 September 2025, namely worn and pitted front brake discs on both sides, grease-covered front brake pipes on both sides, a worn nearside rear upper suspension arm pin or bush, and play in the offside front steering rack inner joint. Looking further back, the October 2024 test cycle repeated this theme with front disc wear, perished lower front suspension arm bushes both sides, an engine oil leak from the central lower area, a greased nearside front brake pipe, and a corroded nearside rear coil spring, while the October 2023 pass added corrosion to both front-to-rear brake pipes at the rear axle and both rear coil springs, alongside a deteriorated nearside front anti-roll bar linkage ball joint dust cover. The persistence of these items across three consecutive test cycles, with brake pipe corrosion, suspension bush wear and coil spring corrosion reappearing year on year, suggests the underlying wear is being monitored rather than resolved, and a buyer should expect at least some of these components to require attention in the near term. Against an age of roughly twelve years, the recorded 139,492 miles equates to an annual accumulation of around 11,600 miles, which sits broadly within the typical band for a vehicle of this vintage and likely reflects steady mixed-use motoring including motorway mileage. There are no significant gaps between tests that would suggest prolonged standing, with annual examinations recorded consistently through 2023, 2024 and 2025, indicating the car has remained in regular service. This continuous usage pattern is mechanically reassuring in that it avoids the typical concerns associated with low-mileage or laid-up vehicles, but the sustained annual mileage does place proportionate demand on consumables such as brake components, suspension bushes and flexible rubber elements, which is consistent with the wear pattern observed in the advisories. For a prospective buyer, the priority items to investigate physically are those that have been flagged repeatedly and have now had time to progress. On a test drive, listen for clonks or thuds from the front suspension over uneven surfaces, which would indicate that the perished lower front suspension arm bushes and worn rear upper arm pin or bush have degraded further; the steering rack inner joint play noted on the offside front should be checked by turning the wheel on full lock at low speed and feeling for any notchiness or clunking transmitted through the rack. Brake feel warrants particular scrutiny, as the pitted front discs may produce pedal pulsation or vibration under firm braking, and any sponginess or excessive travel could indicate that the corroded and greased-over brake pipes, including the front-to-rear lines noted as corroded at the rear in 2023, are restricting hydraulic performance. Visually inspect the coil springs, particularly the nearside rear and both rear springs previously flagged for corrosion, for any signs of cracking or flaking that could compromise structural integrity, and examine the engine bay and undertray area for fresh oil residue tracking from the central lower engine region that was noted as a leak in 2024. Finally, a pre-purchase inspection on a lift would be strongly advisable to assess the full extent of brake pipe corrosion along the chassis legs and rear axle, where surface corrosion can progress to perforation, and to evaluate the anti-roll bar linkage that was flagged for a deteriorated dust cover in 2023, as a torn boot typically leads to accelerated ball joint wear. The undertray fitted at the 2023 test restricted full inspection, so a thorough examination underneath without the trims in place is essential to confirm there are no further developing advisories hidden from view. Budgeting for replacement front brake discs and pads, a set of suspension bushes across both axles, and potential brake pipe refurbishment would be prudent, as these items have been carried forward across multiple tests and are unlikely to remain within advisory limits indefinitely.
