2019 Audi Q5 2.0L Diesel · J444 ABD

A largely unblemished MOT record defines this Audi Q5's mechanical standing, with the vehicle passing four consecutive tests since 2022 and accumulating only a single failure along the way. That 2023 failure was an isolated major defect concerning a nearside front tyre with a cut deep enough to expose the ply or cords, a sudden roadside-type event rather than symptomatic of any underlying mechanical deterioration. The 2024 test returned a fully clean pass, and the most recent examination on 4 August 2025 likewise passed, though it flagged advisories on both rear brake discs for being worn, pitted, or scored without serious weakening. Taken together, the trajectory is one of consistent roadworthiness with the first signs of consumable wear appearing only at the rear braking surface as the vehicle approaches seven years of age. With 34,730 miles recorded against an age of roughly seven years, annual mileage sits at approximately 4,961 miles per year, which is notably low for a vehicle of this class and vintage. Such modest accumulation typically reflects a mix of shorter urban journeys and extended periods of standing rather than sustained motorway use. Mechanically, low mileage reduces wear on major drivetrain components and interior trim but raises the prospect of ageing-related issues in items that degrade with time rather than use, including rubber seals, brake fluid, coolant, and the 12V battery. The presence of pitted rear discs in this context is consistent with infrequent use, as corrosion scoring accumulates on the friction surface whenever a vehicle sits damp for prolonged periods before being driven. For a prospective buyer, the rear brake discs flagged in the 2025 advisory should be the primary inspection focus. On a test drive, listen for any grinding, squealing, or pulsing through the brake pedal that might indicate the pitting has progressed beyond the cosmetic stage, and check visually whether the disc edges show a pronounced lip or visible ridging. The handbrake should hold the vehicle firmly on an incline, as seized rear calipers are common on low-mileage Q5s where the sliding mechanisms seize from infrequent actuation. Inspect the rear pads through the wheel spokes for uneven wear or excessive material loss, as pitted discs accelerate pad consumption. A scan of the rear caliper carriers for surface corrosion is also worthwhile, given the disc condition noted. Beyond the braking system, the remainder of the test drive should concentrate on symptoms associated with underuse rather than high-mileage wear. Pay particular heed to any knocking or clonking from the front suspension over bumps or when turning into kerbs, as the front control arms, drop links, and anti-roll bar bushes on the Q5 are prone to premature deterioration regardless of mileage when subjected to the UK's damp road conditions. Steering should remain precise and free of vibration, and the transmission should select all gears smoothly without hesitation. Inspect the underside for any oil seepage from the engine or transfer case, and confirm that the coolant and brake fluid reservoirs contain clean fluid at the correct levels, as low-mileage vehicles often require a precautionary fluid renewal to ensure ongoing reliability.
