MERCEDES-BENZ E2012 · 2.1L DIESEL

The 2012 Mercedes-Benz E presents a mixed mechanical picture, with a maintenance trend that has recently worsened. In the November 2025 test at 83,489 miles, the tester flagged worn and pitted front inner brake discs, indicating a failure to address the issue properly after the previous day's failure at 83,479 miles. The vehicle passed this retest, yet the advisory remains active, suggesting the discs were borderline rather than replaced. Prior to this, the car enjoyed a clean record with no defects recorded in January 2023, January 2024, or November 2024. The sudden emergence of braking issues and tyre defects points to a recent lapse in basic upkeep. Covering roughly 5,964 miles annually, this E-Class has seen exceptionally light use for its age. The mileage progression shows steady, low accumulation: 70,907 miles in January 2023, 75,010 miles in January 2024, and 78,463 miles in November 2024. The most recent jump to 83,489 miles by November 2025 represents a slightly higher annual total of around 5,000 miles, but remains well below the national average. Such low mileage often implies long periods of standing, which can cause flat-spotted tyres and corroded brake discs, exactly the defects flagged in the latest tests. A physical inspection must thoroughly assess the braking system and wheel components. The tester flagged pitted and scored front inner brake discs, a condition often caused by standing or neglected pad changes. Buyers should measure disc thickness and check for lipping, alongside inspecting the rear tyres for perishing and edge wear noted in the November 2025 failure. The cracking rubber and uneven wear suggest the vehicle has sat stationary for extended periods. Examine the undercarriage for corrosion, as low-mileage vehicles stored outside frequently suffer from structural rust on subframes and suspension mounts. Verify the operation of all lighting, given the recent nearside front position lamp failure.
