2004 Mercedes-Benz A-Class 1.4L Petrol · LS04 AOB

A 2004 Mercedes-Benz A-Class carrying over two decades of service presents an unusual MOT history in that every recorded test in the past several years shows either a pass with no advisories or a fail with no defects recorded, leaving the actual mechanical condition unclear from the official data alone. The most recent test on 22 December 2022 returned a clean pass with no defects, advisories, or worn-component notes, and this is consistent with the earlier pass on 26 November 2021. However, it is worth noting that the two failures recorded, on 16 December 2022 and 23 November 2021, both occurred within days of a subsequent pass and likewise contain no defect entries, which is atypical and may indicate administrative retests following very minor, quickly rectified issues, or alternatively a record-keeping irregularity. Without defect details, the mechanical trend cannot be definitively classified as stable or worsening, but the clean advisory-free passes suggest the vehicle has not been flagged for any wear items at recent inspection. Mileage data is not available in this MOT history, which limits any judgement on how the car has been used over its lifetime. A 2004 vehicle is now 22 years old, and a typical car of this age would have covered somewhere between 80,000 and 150,000 miles depending on its usage pattern, but without recorded odometer readings it is impossible to confirm whether this example has been driven regularly, used sparingly, or potentially stored for extended periods. The testing gaps are also worth considering: only four MOT events are recorded, all within a 14-month window in late 2021 and late 2022, with nothing shown before November 2021, which could suggest the vehicle was either off the road for some time prior or that earlier test records are simply not present. Prospective buyers should request the full service history and verify current mileage against the V5C logbook to establish a clear picture of how this car has been used. Given the complete absence of advisory notes on the recorded passes, there are no specific components documented as showing wear, so a physical inspection becomes particularly important. On a test drive, pay close attention to the suspension behaviour, as the W168 A-Class is known for ageing front and rear coil springs, worn suspension bushes, and occasional knocking from the lower wishbone joints; listen for clonks over speed humps and uneven road surfaces, and feel for any vagueness or vibration through the steering wheel. The braking system should be checked for a firm pedal with no judder under heavy application, and the car should pull up in a straight line, as older A-Class models can suffer from binding calipers and worn front discs that lead to uneven pad wear. Additionally, inspect the underside thoroughly for corrosion on the subframe, suspension arms, and brake pipes, as vehicles of this age and era are particularly susceptible to structural surface rust in these areas even when no advisory has been raised at a recent test. Finally, because the MOT record contains no defect information at all across four tests, it is essential to commission an independent pre-purchase inspection from a Mercedes-Benz specialist or a qualified technician before committing to purchase. Request that they pay particular attention to the engine and gearbox for oil leaks, as M-Class and A-Class units of this era are prone to seepage from the sump and valve cover gaskets, and check the condition of the timing chain on petrol variants, which can stretch with age. Confirm that all electrical systems, including the central locking, dashboard warning lights, and the distinctive A-Class pedal box adjustment mechanism, are operating correctly, and ask for a compression test on the engine to verify internal condition. With the MOT history offering no specific flagged concerns, the responsibility falls on a hands-on mechanical assessment to confirm that this now-22-year-old vehicle remains structurally sound and mechanically fit for continued road use.
