2008 Mazda 5 2.0L Diesel · OV08 XML

The latest MOT test in June 2023 resulted in a pass with a single advisory noting slight play in the offside rear anti-roll bar linkage ball joint. Reviewing the broader history, the maintenance trend shows a pattern of recurring suspension and tyre advisories, with a notable failure in 2020 due to perished anti-roll bar linkage dust covers, which were subsequently addressed. While the vehicle has passed each test since, the persistence of suspension-related advisories—particularly around rear trailing arm bushes and anti-roll bar linkages—suggests a gradual deterioration of these components. The trend is neither significantly worsening nor improving but indicates that these areas require close attention. At 18 years old with 96,454 miles recorded, the annual mileage averages around 5,359 miles, which is relatively low for its age. This suggests the vehicle may have spent extended periods stationary, which can lead to its own set of issues such as corrosion of brake discs, seizing of calipers, or degradation of rubber components like bushes and tyres due to age rather than wear. Low mileage can also mean that fluids, such as coolant, brake fluid, and automatic transmission fluid if applicable, may not have been refreshed as frequently as they should have been based on time rather than distance. The recurring advisories on the anti-roll bar linkages and rear trailing arm bushes are critical areas to inspect. On a test drive, listen for clunks or knocks from the rear suspension when traversing uneven surfaces, as this could indicate worn bushes or ball joints. Excessive play in the anti-roll bar linkages may also manifest as vague or imprecise handling during cornering. The tyres have repeatedly been flagged for edge wear, which often points to incorrect wheel alignment or underinflation; check for uneven tread wear and ensure a four-wheel alignment is carried out if new tyres are fitted. Additionally, inspect the brake discs for surface corrosion or scoring, and verify that the calipers are not binding, as prolonged standing can cause these issues. Given the vehicle’s age and low mileage, pay particular attention to time-based degradation. Examine the tyres for sidewall cracking or perishing, as rubber hardens and deteriorates with age regardless of tread depth. Test the 12V battery’s condition, as older batteries can fail without warning, especially if the car has been used infrequently. Check for fluid leaks under the vehicle and verify the service history to ensure that all time-sensitive fluids have been replaced. Finally, inspect the exhaust system for corrosion, particularly at joints, and assess the overall structural integrity for rust, especially in wheel arches, sills, and underseal areas, as these are common problem areas for vehicles of this age.
