2016 Mercedes-Benz A-Class 1.6L Petrol · DC66 NPD

The most recent MOT test on 15 August 2026 resulted in a pass, but it is worth noting that the vehicle also failed an earlier test on the very same date before subsequent repairs were carried out to address the major defects of a nearside front headlamp aim that was too low and an inoperative nearside front position lamp. While the car is now roadworthy and the advisories remaining are relatively minor, the immediate re-test scenario indicates that the vehicle was being prepared to pass rather than reflecting a long-standing trend of diligent maintenance. Looking back across the recorded history, the pattern is broadly stable but punctuated by recurring concerns, with multiple advisories issued for the nearside front lower suspension arm ball joint and the offside front steering rack inner joint, alongside a prior failure in 2025 related to the supplementary restraint system warning lamp, which was rectified prior to the subsequent pass. The presence of repeated advisories on steering and suspension components does suggest that these areas are gradually deteriorating rather than being proactively addressed. With a recorded mileage of 106,399 miles over approximately ten years, this A-Class has averaged around 10,640 miles per year, which is broadly typical for a vehicle of its age and class. There are no obvious gaps in the MOT history that would imply long periods of standing, and the consistent annual accumulation of around ten to eleven thousand miles suggests regular use, which is generally beneficial for keeping mechanical components, seals, and fluids in working order. That said, at this mileage the engine, transmission, and drivetrain will have accumulated significant wear, and items such as the timing chain, turbocharger (if applicable), clutch, and dual-clutch transmission components (where fitted) should be regarded as having entered the latter stages of their expected service life, particularly on a Mercedes-Benz of this vintage. The most pressing area of concern from the MOT record is the front suspension and steering. The advisory on the nearside front lower suspension arm ball joint with slight play indicates wear in a component that typically progresses over time and will eventually require replacement, particularly on a vehicle that has covered over one hundred thousand miles. On a test drive, you should listen for any clonking or knocking noises from the front end, particularly over speed bumps, potholes, or uneven road surfaces, and pay attention to vague or wandering steering responses, as the noted play in the offside front steering rack inner joint could also manifest as imprecise handling or a slight vibration through the steering wheel. The previous failure concerning the supplementary restraint system warning lamp should not be dismissed lightly, as it relates to the airbag or seatbelt pretensioner system, and it would be prudent to confirm with the seller that the fault was properly diagnosed and rectified rather than simply cleared from the system, and to verify that no warning lamps remain illuminated on the dashboard at the point of sale. Beyond the documented advisories, a prospective buyer should carry out a number of physical checks appropriate to the vehicle's age and mileage. The 2024 advisories for slight cracking and perishing on both rear tyres highlight a common issue with age-related rubber degradation, and even if those tyres have since been replaced, the spare wheel and any older tyres should be inspected for sidewall cracking. Given the vehicle's age, the condition of the braking system warrants close attention, with particular focus on the nearside rear brake pads which were noted as wearing thin on the recent test; on a test drive listen for any grinding or squealing and check for brake shudder or pull under heavy braking. The coolant, brake fluid, and automatic transmission fluid (where applicable) are all likely due for replacement on a calendar basis regardless of mileage, and the twelve-volt battery should be tested for its state of health, as a ten-year-old vehicle will almost certainly require a new battery imminently. Finally, given the high mileage, it would be wise to request evidence of recent major servicing, including cambelt or timing chain inspection records, and to commission an independent pre-purchase inspection to assess areas such as oil leaks from the engine and gearbox, exhaust corrosion, and the general condition of the underbody.
