2013 Mercedes-Benz CLS 2.1L Diesel · DA63 EUX

The vehicle presents a complex history of reactive maintenance, despite the most recent test on 26 March 2026 at 49,966 miles showing no defects. Looking back, the data reveals a persistent trend of corrosion in the braking system components. In October 2025 at 47,828 miles, the car failed due to a holed offside rear sub-frame and a fractured offside rear coil spring, alongside significant sidewall damage to both front tyres. While these issues were rectified for the subsequent pass, the presence of structural corrosion on the sub-frame suggests that environmental damage is being addressed only upon failure rather than through preventative measures. At 49,966 miles over 13 years, the car has averaged approximately 3,844 miles per year. This low-use profile often correlates with the degradation of rubber components rather than mechanical wear. The record confirms this, as repeatedly between 2021 and 2023, the nearside and offside rear brake pipes were flagged for corrosion and being covered in grease. The failure in October 2024 at 44,257 miles for excessive pipe corrosion and defective wiper blades indicates that basic upkeep and fluid line integrity were neglected until the annual test forced action. A buyer should focus on the structural integrity of the sub-frame and the condition of the suspension assembly, given the 2025 failure in these areas. The recurring issue with corroded brake pipes across multiple years suggests the vehicle may have been stored in harsh conditions or sat for long periods. Given the low mileage, it is also vital to inspect for perished tyres and dry bushings, as the 2022 advisories already highlighted cracking and perishing in the rubber despite the low distance driven.
