2017 Mercedes-Benz A-Class 1.6L Petrol · LM06 MAS

The most recent DVSA MOT test on the 2017 Mercedes-Benz A-Class occurred on 2025-10-15, where it passed with a single advisory regarding the near-side front lower suspension arm ball joint exhibiting slight play, a condition that was also noted in the preceding MOT on 2025-10-08, which failed due to a major defect in the near-side front anti-roll bar linkage ball joint dust cover failing to prevent dirt ingress. This pattern indicates a recurring issue with the front suspension ball joints, suggesting a potential underlying wear problem that has not been fully addressed. The earlier passing MOTs from 2023 to 2021 show no defects, implying that while the ball joint concerns have persisted, they may not have escalated to critical failure states during those intervals. However, the failure in 2025-10-08 highlights a need for proactive intervention, as the ball joint’s integrity is critical to steering stability and suspension performance. The recorded mileage of 61,051 miles for a vehicle aged nine years represents a moderate annual usage rate of approximately 6,783 miles per year, which is typical for this model’s age group. Such mileage accumulation is generally consistent with regular driving, though it does not necessarily indicate excessive wear if the vehicle has been maintained appropriately. However, the presence of multiple advisories related to suspension components—particularly the ball joints—suggests that the vehicle may have experienced periods of higher stress or improper maintenance, which could accelerate wear in these critical areas. The anti-roll bar linkage ball joint failure in 2025-10-08 is particularly concerning, as this component is designed to resist lateral forces and maintain suspension alignment; its failure to maintain dust exclusion could lead to premature joint failure or contamination of lubricants, exacerbating further damage. Without evidence of recent servicing or replacement of these components, the buyer should be cautious of potential future suspension failures. To proceed with a thorough inspection, the prospective buyer should begin by examining the front suspension for any signs of excessive play or binding, particularly around the near-side lower arm and anti-roll bar linkage. On a test drive, listen for unusual clunking or rattling noises from the front suspension, especially when navigating bumps or sharp turns, as these could indicate worn ball joints or damaged suspension bushes. Visually inspect the front tyres for uneven wear patterns, which may suggest misalignment or suspension issues, and check for any cracks or perishing in the sidewall, as noted in the 2024 MOT advisories. Additionally, verify that the front brake discs and pads are free from corrosion or binding, as thin pad wear was also flagged in the 2021 MOT. Inspect the anti-roll bar linkages for any signs of rust or damage, and ensure the ball joint dust covers are intact and properly sealed. If the buyer suspects persistent suspension play, they should also check the steering wheel for excessive movement or vibration, as this could indicate a failing steering rack or tie rod ends. Given the recurring advisories and the failure in 2025-10-08, the buyer should prioritise replacing the near-side front anti-roll bar linkage ball joint and its dust cover as soon as possible, ideally before the next MOT. The near-side front lower suspension arm ball joint with slight play should also be addressed, as this could lead to steering instability or premature suspension component failure. The tyre advisories from 2024 suggest that the front tyres may have reached a stage where they are nearing their useful life, particularly if the cracks or perishing are worsening. Replacing these tyres would be prudent, especially if the vehicle is driven regularly, as compromised tyres pose safety risks. For the brakes, since thin pad wear was noted in 2021, the buyer should check the condition of the brake discs and pads again, ensuring they are not binding or corroded, and consider a brake fluid flush if the vehicle has been stationary for extended periods, as brake fluid degrades over time. Finally, the buyer should request service records to confirm whether the suspension components have been serviced or replaced, as the lack of such documentation raises concerns about maintenance history. If the vehicle has been driven at a moderate rate, the 12V battery and fluid levels should also be checked, as standing vehicles can lead to battery corrosion or fluid degradation.
