2013 Mercedes-Benz E 2.1L Diesel · LO62 OBB

The defining mechanical characteristic of this 2013 Mercedes-Benz E is a pattern of front brake disc degradation appearing across the most recent inspections, combined with two historical failures involving the rear tyres and the nearside front coil spring. The 2026 test on 23 June passed with advisories on both front brake discs for wear, pitting, and scoring, repeating exactly the advisories issued on the same components during the failed test eight days earlier on 15 June. That earlier test was failed for dangerous tread depth breaches on both rear tyres, indicating the vehicle was driven with rear tyres below the legal 1.6mm limit before being rectified. Looking further back, the 2022 test failed on a fractured nearside front coil spring and dangerous structural bulges in both rear tyres, yet the intervening tests in 2023, 2024, and 2025 recorded no advisories at all. The overall trend is therefore one of intermittent rather than chronic issues, with the front brake discs emerging as the principal recurring concern in the latest cycle. With 77,162 miles recorded over roughly 13 years, the vehicle has covered approximately 5,936 miles annually, which is low for a car of this age and points to either light running or extended periods of inactivity. The MOT history shows no multi-year gaps in testing, with annual examinations consistently recorded from 2021 onwards, so there is no evidence of a formal off-road declaration through the SORN process within the visible record. However, such modest annual mileage on a Mercedes-Benz E-Class raises the usual mechanical considerations: standing time can affect brake discs and pads through surface corrosion even when mileage is modest, and the recurring advisories on both front discs for pitting and scoring are consistent with vehicles that complete short journeys with extended gaps between use. Suspension components, coolant seals, and the air conditioning compressor are also typically more vulnerable when the vehicle is not exercised regularly over longer distances. For a prospective buyer, the front brake discs are the immediate priority and warrant close physical inspection. Both units were flagged for pitting and scoring in June 2026 and should be measured for remaining thickness against the manufacturer minimum, as continued use of worn discs will accelerate pad wear and may require disc replacement alongside the pads. On a test drive, listen for any grinding or vibration through the brake pedal under firm application and check for any steering wheel shudder, which on a Mercedes of this era is often traceable to warped or heavily corroded front discs. The nearside front coil spring fractured in 2022, and although no recurrence has been recorded, the replacement should be confirmed and the offside front spring and all rear springs should be visually checked for cracking, particularly around the lower coils where fractures typically initiate. Any clonking or harshness over single speed bumps in the test drive would warrant further investigation of the spring seats and top mounts. The rear tyres have been the source of two separate dangerous failures within the record, once for tread depth below 1.6mm and once for structural bulges indicating casing failure. A 2021 advisory also noted heavy perishing between the tread blocks on the nearside rear, suggesting the tyres were either ageing on the vehicle or had covered very few miles between rotations. At the viewing, all four tyres should be inspected for manufacture date, even tread wear across the axle, and any signs of sidewall cracking or bulges, and the spare wheel should be checked for pressure and condition given the recurring rear axle concerns. Beyond the flagged items, the remainder of the recent record is clean, but the brake fluid, coolant, and automatic transmission fluid service intervals should be verified through the service documentation as low annual mileage does not eliminate the time-based degradation of fluids and rubber components throughout the braking, cooling, and drivetrain systems.
