2014 Mercedes-Benz B-Class 1.5L Diesel · LF14 PRV

The vehicle is currently roadworthy, but the most recent test history indicates a specific electronic concern that requires attention. While the car passed its September 2025 test at 95,127 miles, it initially failed due to an inoperative Malfunction Indicator Lamp (MIL) and a restricted inspection caused by a child seat. The failure of the MIL is a significant finding as it prevents the driver from being alerted to engine management or emissions faults. Despite the subsequent pass, this fault marks a departure from the clean records seen in previous years. The mileage pattern remains consistent with typical usage for a vehicle of this age, averaging 8,000 miles per annum. Between March 2022 at 69,172 miles and September 2025 at 95,127 miles, the car covered over 26,000 miles, showing steady and predictable use. The lack of advisories during the 2023 and 2024 tests suggests that previous owners maintained the mechanical and structural components well, as no issues with corrosion, corrosion, or brake wear were flagged during that period. A buyer must prioritise a professional diagnostic scan to verify why the MIL was inoperative during the 2025 test. If the bulb was simply bypassed or the sensor faulty, it could mask underlying engine issues that would remain undetected. Given the vehicle is approaching the 100,000-mile mark, a physical inspection of the front suspension bushes and control arm ball is advisable, as these components often suffer from age-related degradation regardless of low mileage. The clean history suggests a solid foundation, but the recent electronic failure must be cleared before any purchase.
