2012 Mercedes-Benz E 2.1L Diesel · K555 ACP

The 2012 Mercedes-Benz E class presents a clean MOT pass record, with the most recent test on 16 December 2025 at 54,422 miles confirming roadworthiness. The trend is stable, not worsening, though the tester noted the near-side front brake pipe as corroded and covered in grease or other material, and recorded slight corrosion to the rear subframe. This mirrors a similar brake pipe advisory from the 2021 test at 44,832 miles, meaning the corrosion is a recurring area of attention rather than a sudden failure. The mileage history fits a low-use pattern. Over roughly fourteen years the car has covered 54,422 miles, averaging about 3,887 per year. The yearly test intervals show no dramatic jumps: 2,467 miles between December 2021 and December 2022, 1,760 miles to 2023, 2,824 miles to 2024, and 2,539 miles to the 2025 test. That consistency suggests regular light use rather than prolonged standing or heavy motorway work. The three intervening tests recorded no defects at all, which points to a generally sound underlying structure. A buyer should physically inspect the near-side front brake pipe, because the grease covering can mask the true extent of corrosion. Check the full length of the pipe for flaking metal or any soft spots. The rear subframe also warrants a close look, especially around mounting points and where the coating has broken down. Given the car's age, minor surface corrosion on subframes is common, but any deep pitting or section loss would require immediate attention. The rest of the history is clean, so the brake pipe and subframe are the two items that separate this car from a completely fault-free example.
