2011 Mercedes-Benz E 3.0L Diesel · AK51 ALS

The vehicle is currently roadworthy but the most recent inspection indicates a shift from a clean record to active mechanical degradation. While the car maintained a perfect history for several years, the April 2026 test at 98,318 miles revealed three distinct defects. The tester identified corrosion on both nearside and offside rear brake pipes obscured by grease alongside a worn nearside front coil spring. This suggests that components are now beginning to fail rapidly after a long period of stable operation. Mileage accumulation remains consistent with a low-to-moderate usage profile, averaging approximately 6,500 miles per year. There is a notable gap in records between October 2022 and March 2024, where the vehicle covered roughly 14,000 miles in seventeen months. However, the usage rate increased significantly recently, with 24,129 miles logged between March 2024 and April 2026. This sudden surge in driving often accelerates the wear of aged rubber components and metal fatigue, leading to the failures in the latest MOT test. A buyer must perform a thorough physical inspection of the braking system to ensure the corrosion on the rear pipes is not structural. The presence of grease on these pipes often indicates an attempt to hide weeping leaks or heavy rust, which warrants close scrutiny. The worn front coil spring should also be checked for cracks or further sagging, as failure of this component can affect steering geometry and safety. Given the age of the vehicle and the recent appearance of corrosion, the chassis and underbody should be inspected for structural integrity to ensure the rust on the brake lines is not isolated.
