2007 Mercedes-Benz A-Class 1.5L Diesel · SP07 LSC

The most recent MOT, dated 2 June 2026, was a pass but returned a series of corrosion‑related advisories covering the fuel tank, shock‑absorber casings, suspension‑mounting areas and the rear sub‑frame. Earlier in the same month the vehicle failed on a number of major items, and over the past three years the record shows a mixture of failures and passes with recurring advisories for brake‑pipe corrosion, deteriorating hoses and minor lighting faults. The pattern suggests that the vehicle’s condition has moved from outright failures towards a passable state, yet the persistence of corrosion points to a maintenance trend that is stabilising only because the most serious safety items have been addressed, while age‑related wear remains unmitigated. At 112,915 miles on a 2007 model the average annual mileage works out to roughly 5,900 mi, considerably below the typical UK usage of 8‑12 000 mi per year. This low figure is consistent with either light, infrequent use or extended periods of storage. Light mileage reduces the wear rate on consumables such as tyre tread, brake pads and engine bearings, but it also means that components susceptible to calendar ageing—rubber seals, hoses, battery plates and corrosion‑prone steel—have been exposed to the elements for a long time without the protective benefit of regular heat cycles. Consequently, the vehicle may exhibit age‑related deterioration despite the modest mileage. A prospective buyer should give particular attention to the corrosion noted on the fuel tank, the rear sub‑frame and the various suspension mounting points. Visually inspect the tank for any signs of rust penetration or flaking that could lead to fuel leaks, and listen for a faint hissing or fuel odour when the engine is running. The rear sub‑frame should be examined for any rust streaks or pitting that could compromise structural rigidity; any flex or audible clunk when applying torque to the rear wheels may indicate weakening. The shock absorbers should be checked for oil seepage around the casings and for excessive bounce or a hollow feel when the vehicle is pressed down, which would signal worn internal components. Brake‑pipe and hose corrosion, repeatedly flagged in the MOT history, warrants a thorough inspection for rust, cracking or grease buildup, and the brake pedal should feel firm with no pulsation; any sponginess or grinding noises could reveal compromised pipe integrity or deteriorated pads. Finally, verify that the supplementary restraint system warning lamp is illuminated correctly, and confirm that the rear registration plate is legible and securely mounted, as previous failures have highlighted these safety concerns. Given the vehicle’s age, the buyer should also conduct a comprehensive age‑related check irrespective of mileage. Examine all tyres for sidewall cracking, dry rot or loss of tread even if the depth appears adequate, and confirm that the tyre DOT code is no more than six years old. Test the 12 V battery under load, as prolonged standing can cause sulphation and reduced cranking power. Drain and replace all engine and brake fluids if there is no recent service record, since fluids degrade over time and can lead to internal corrosion. Inspect the coolant reservoir, radiator and hoses for any signs of swelling, leaks or crusted deposits, and ensure that the windscreen washer system delivers a steady spray, as a previous failure indicated insufficient liquid. A full service book review, confirming regular oil changes, timing‑belt or chain service, and any corrective work on the noted corrosion points, will give the clearest indication of whether the vehicle has been kept in a roadworthy state despite its low mileage.
