2009 Mercedes-Benz B-Class 2.0L Diesel · YX09 WKT

The vehicle is currently roadworthy, but the maintenance trend indicates a reactive approach rather than proactive care. While the most recent test in June 2025 at 97,280 miles resulted in a pass, the tester was restricted by child seats preventing a full inspection of the seatbelts. This follows a failure in June 2024 where the car failed on headlamp alignment issues and brake-related defects, suggesting that mechanical faults are only addressed once they reach a point of inspection failure. At 17 years old, this Mercedes-Benz B-Class shows a relatively low mileage profile, averaging approximately 5,700 miles per year. However, there is a significant gap in data between May 2023 and June 2024, where the vehicle covered 15,384 miles in just thirteen months. This sudden burst of use contrasts with previous years of lower activity and explains the rapid wear noted on the braking components. The low annual mileage often leads to the degradation of rubber components and seals, which is evident in the older inspection records. A buyer must personally inspect the front suspension and braking system due to recurring reports of wear. The 2022 test flagged corroded anti-roll bar linkages and corroded coil springs, which are common failure points on this chassis as they age. Furthermore, the 2024 records noted thin nearside front brake pads and a fluctuating brake surface, which often indicates warped discs or a sticking caliper piston. The buyer should also verify that the front oil leak identified in 2022 has been rectified, as persistent leaks can lead to engine damage if left unmonitored.
