2009 Audi A4 2.0L Diesel · BJ59 LLC

The vehicle passed its most recent MOT on 23 September 2025 at 195,604 miles, but the failure just 13 days earlier reveals an unresolved critical defect: the nearside front outer CV joint boot is severely deteriorated. This is not a new issue—it was flagged in both the 2025 and 2024 tests—indicating a persistent failure to address basic drivetrain maintenance. The fact that the same fault persisted across two consecutive tests, despite the car being driven regularly, suggests a pattern of deferred repairs that compromises long-term reliability. The recorded mileage of 195,604 miles over 17 years equates to roughly 11,500 miles annually, which is typical for a vehicle of this age. However, the jump from 177,733 miles in September 2024 to 195,604 miles in September 2025 shows a 17,871-mile increase in just one year, significantly above average. This rapid accumulation implies heavy usage in the last 12 months, likely accelerating wear on components already flagged as worn or damaged, such as the suspension arm bush and CV joint. A buyer must inspect the nearside front CV joint immediately; the boot’s failure will lead to grease loss and rapid joint destruction, potentially causing sudden drive failure. The headlamp fault from the September 2025 failure was corrected, but the prior mention of a broken top mount in 2024 raises questions about the quality of previous repairs. The upper suspension arm bush wear noted in 2022 has not been mentioned since, yet it remains a likely point of degradation given the mileage surge. The tyre damage from 2022 may have been patched or replaced, but the lack of subsequent tyre-related advisories doesn’t guarantee current tread depth or sidewall integrity. There are no signs of structural corrosion in the record, but the age and usage pattern warrant a thorough underbody inspection for rust, especially around wheel arches and suspension mounts.
