2009 Mazda 3 2.0L Diesel · SL09 WVC

The most recent MOT test for this 2009 Mazda 3 occurred on 2022-10-24, resulting in a passing grade with several persistent advisories and minor failures that have been recurrent over the past five years. While the vehicle has passed subsequent MOTs, the pattern of repeated nearside front drive shaft CV boot failures—both outer and inner joints—suggests a consistent mechanical issue that requires immediate attention. The oil leak advisories from 2020 onwards indicate a persistent, though not excessive, fluid loss, which could stem from a failing oil seal or gasket, particularly around the CV joints or transmission area. The minor exhaust leaks and anti-roll bar ball joint play advisories also reflect ongoing wear in suspension components, which, if left unaddressed, may lead to further structural or handling degradation. The 2018 failures—particularly the front and rear anti-roll bar ball joints with excessive play—highlight a recurring problem with suspension linkage integrity, warranting a thorough inspection of these components for long-term reliability. The vehicle’s recorded mileage of 135,439 miles at 17 years old represents a moderate annual usage rate of approximately 7,967 miles per year, which is typical for a car of this age and class. Such mileage accumulation over time does not necessarily indicate excessive wear if usage patterns were consistent, but the presence of multiple MOT failures and advisories suggests either prolonged exposure to harsh conditions or a history of neglect in addressing wear-related issues. The absence of a significant gap between the latest MOT and the previous failures implies that the vehicle has been driven regularly, which could accelerate the deterioration of consumables like seals, bushings, and suspension components. For a buyer, this profile suggests that while the car may have been maintained within legal limits, it has not been serviced proactively to mitigate wear progression, particularly in the drivetrain and suspension systems. Given the recurring CV boot failures and oil leak advisories, the prospective buyer should prioritise a detailed inspection of the near-side front drivetrain components, focusing on the CV joints, their boots, and associated seals. On a test drive, listen for unusual noises from the front wheels, particularly when transitioning between gears or accelerating, as a failing CV joint may produce a whining or grinding sound. Check for oil leaks around the transmission area, particularly beneath the vehicle, and visually inspect the CV boots for cracks or tears. If the boots are severely deteriorated, replacement is strongly advised to prevent further oil loss and potential joint damage. Additionally, the persistent suspension ball joint issues—including the 2018 failures and ongoing play advisories—demand inspection of the anti-roll bar linkages, suspension arms, and bushings. Look for excessive movement in the ball joints, clunking noises during cornering or over bumps, and uneven suspension travel. If any ball joints are worn beyond the MOT-advised limits, replacement is necessary to maintain handling stability and prevent further structural wear. For the buyer, the vehicle’s age and mileage profile necessitate a comprehensive physical inspection beyond the MOT checks. Given the recorded tyre wear advisories, particularly the 2018 and 2017 close-to-legal limits, verify the tyre condition by checking for uneven wear patterns, which could indicate misalignment, suspension issues, or improper inflation. Inspect the tyre sidewalls for signs of perishing or cracking, which can weaken the tyre structure and reduce safety over time. The chassis corrosion advisories from 2019 and 2020 indicate that the vehicle has been exposed to moisture, especially in areas near mounting points. Visually inspect the undercarriage, particularly the lower sills and wheel arches, for rust progression, which could compromise structural integrity. A 12V battery health check is also prudent, as prolonged standing or low usage can lead to battery failure, especially in older vehicles. Finally, since the vehicle has not been serviced for fluid changes beyond the MOT intervals, consider a check on the brake fluid, coolant, and transmission fluid for signs of degradation or contamination. If the service history is sparse, plan for a full fluid top-up and replacement of any fluids nearing their service life, as fluid degradation can accelerate wear on components like brake pads, seals, and suspension bushings.
