2017 Audi Q5 2.0L Diesel · CV67 JFJ

Chronic corrosion of the rear suspension and structural components has emerged as the primary mechanical concern, marking a shift from a previously clean testing history. While the vehicle passed its latest inspection on 2026-08-05, the record shows a worsening trend of advisories regarding the rear subframe and coil springs that first appeared in 2025. The presence of plastic under-trays has been a recurring note since 2023, which has hindered the inspector's ability to fully examine the underside of the chassis. An accumulation of 61,768 miles over approximately nine years represents a typical usage pattern of roughly 6,863 miles per year. This consistent level of use suggests that drivetrain and engine components have not been subjected to extreme high-mileage wear, nor has the vehicle suffered from the degradation associated with prolonged periods of inactivity. Mechanical wear is likely consistent with the age of the vehicle, though the emerging corrosion indicates that environmental factors have had a more significant impact than sheer mileage. Particular attention must be paid to the rear suspension, as both the nearside and offside rear coil springs have been flagged for corrosion across the last two test cycles. During a test drive, listen for audible knocks or metallic clunks when traversing speed bumps or uneven road surfaces, as corroded springs are prone to fatigue and eventual failure. A physical inspection of the rear wheel arches and suspension mounts is necessary to determine the extent of the metal degradation. The reported corrosion on the rear subframe is a significant point for further investigation, as structural integrity is paramount for roadworthiness. Because the DVSA records explicitly mention that under-trays have obscured underside components, a professional inspection involving the removal of these trays is required to assess whether the subframe corrosion is superficial or structural. Check for any unusual vibrations or instability in the rear end during cornering, which could indicate compromised suspension mounting points.
