2006 Audi A4 1.9L Diesel · C28 REK

The vehicle’s most recent MOT test on 2025-10-15 confirms it remains roadworthy, with no defects or advisories recorded across the past three consecutive tests. This suggests a stable maintenance history over the last two years, though the single failure in 2024-10-25 (a duplicate entry with no recorded issues) appears anomalous and likely a data error rather than a mechanical trend. The absence of recurring advisories or defects implies the vehicle has not experienced persistent problems with suspension bushes, coil springs, binding calipers, or structural corrosion—common concerns for a 2006 A4 at this mileage. However, the lack of advisories does not preclude hidden wear, particularly in high-stress areas like the drivetrain or exhaust system, which often require closer inspection beyond MOT thresholds. The recorded mileage of 115,365 miles over 20 years equates to approximately 5,768 miles annually, a figure significantly lower than average for a vehicle of this age. This suggests either minimal use or prolonged periods of inactivity, which could mitigate some wear but may also indicate deferred maintenance. Notably, there are no gaps in MOT testing beyond the expected annual cycle, though the 2024 failure entry—with no defects—raises suspicion of administrative inconsistency. The consistent testing pattern does not reveal rapid mileage accumulation, but the low annual mileage could mean some components, such as brake pads or timing belt (if applicable), may have been serviced less frequently than manufacturer recommendations. A buyer should prioritise an in-person inspection of the suspension geometry, particularly the rear bushes and coil springs, as these often degrade predictably over time. The brakes, including caliper binding and disc thickness, should be checked for uneven wear or corrosion, especially given the low mileage could mask gradual deterioration. Structural integrity, particularly around the sills, wheel arches, and subframe, warrants scrutiny for corrosion, as this is a critical failure point for older Audi models. Finally, the exhaust system—especially at the rear—should be examined for leaks or excessive rust, as emissions-related failures are not recorded in the MOT history but can develop silently. Given the lack of advisories, the vehicle appears mechanically sound on paper, but these areas demand thorough verification.
