2013 Mercedes-Benz B-Class 1.8L Diesel · AX13 BUP

A clean and unblemished MOT record across the four documented tests from 2024 through 2026 demonstrates consistent roadworthiness for this thirteen year old Mercedes-Benz B-Class, with no advisories, minor defects, or structural corrosion logged at any stage. The pattern of a pass immediately following each failure is simply the standard DVSA administrative sequence, where a vehicle presented in a failed condition is re-presented and passes on the following day once the presenting issue is resolved. Both retests returned clean sheets with no defects recorded, meaning whatever caused the initial refusals did not constitute a category of failure that would be expected to recur. Overall, the mechanical trajectory is stable and reassuring, with no escalation in advisory severity and no evidence of progressive wear issues that typically signal deeper underlying concerns. Against a typical annual mileage of around eight to ten thousand miles for a car of this age and class, the recorded 53,750 miles over thirteen years equates to roughly 4,135 miles annually, which sits comfortably in the low-use bracket. This relatively modest accumulation is consistent with second-car duties, short urban errands, or a vehicle that has spent extended periods either garaged or lightly used. Mechanically, lower mileage reduces wear on major drivetrain and suspension components such as the clutch, turbocharger, and dampers, but it does elevate the risk of issues stemming from infrequent use. Rubber components including the drive belts, coolant hoses, suspension bushes, and tyre sidewalls can deteriorate through age and UV exposure rather than through active wear, and seals that remain static for long intervals are more prone to drying out and weeping. Given the sparse advisory history, a prospective buyer should direct attention during inspection toward the age-related vulnerabilities typical of the B-Class platform. On a test drive, listen for clonking or knocking from the front suspension over uneven surfaces, which would point to worn lower control arm bushes or anti-roll bar drop links, and feel for any vagueness or wandering in the steering that might indicate perished front wishbone bushes. The W246 generation B-Class is also known for sensor faults, particularly with the parking sensors and the steering angle sensor, so verify that all dashboard warning lamps extinguish promptly on start-up and that the EPAS system returns accurately to centre after cornering. Check the underside for any signs of oil misting from the cam chain cover, which is a known issue on the M270 and M133 petrol engines, and inspect the condition of the undertrays, as their absence often conceals early corrosion around the front subframe mounting points. The brake system warrants particular scrutiny given the vehicle's age. Examine the inner and outer faces of both front discs for a pronounced lip, scoring, or corrosion pitting, and feel through the pedal for any judder under firm braking that would suggest disc runout. The rear drums on entry-level variants should be inspected for surface corrosion, although light oxidation is typical and not itself a failure item. Tyres should show even wear across the tread, as inner shoulder wear on the front axle can indicate worn suspension geometry or alignment drift. Finally, confirm that the air conditioning system produces cold output, as condenser and refrigerant degradation are common on B-Class models of this vintage, and ensure the seven-speed dual-clutch transmission (where fitted) shifts smoothly between first and second gear without the characteristic judder that develops as mechatronic wear progresses.
