2017 Audi Q5 2.0L Diesel · H11 RAF

The latest MOT test in February 2026 resulted in a pass, though it carried an advisory for thin rear brake pads and followed a failure just three days prior due to a fractured offside rear coil spring and an inoperative or malfunctioning engine management light. The preceding year’s test in February 2025 also failed initially for a fractured nearside rear coil spring and the same engine MIL issue, indicating a recurring and serious suspension defect that has now affected both rear springs. While the vehicle passed cleanly in 2024 and late 2023, the re-emergence of these major defects in 2025 and 2026 suggests a worsening trend in structural and electrical reliability, despite the absence of other persistent advisories. At 98,221 miles over nine years, the annual mileage averages around 10,900 miles, which is typical for a vehicle of this age and does not indicate excessive or unusually low usage. This rate suggests moderate wear on consumables such as brakes, tyres, and suspension components, though the repeated coil spring failures at this mileage are concerning and may point to either poor road conditions, heavy loading, or a batch-related material defect. The mileage does not reveal prolonged periods of inactivity, which reduces the likelihood of standing-related issues such as seized calipers or corroded discs, but it does not absolve the need for age-related checks. The fractured rear coil springs are a critical safety concern, as a broken spring can cause a sudden loss of suspension control, uneven tyre wear, and a noticeable clunking or knocking noise over bumps, particularly from the rear. On a test drive, listen for metallic clunks or rattles from the rear suspension, and inspect the spring seats and surrounding components for damage or misalignment. The thin rear brake pads advisory, recurring since 2021, should be addressed immediately, as further wear will lead to metal-on-metal contact, scoring of the brake discs, and a significant reduction in braking efficiency. Additionally, the engine management light fault, which has caused two MOT failures, must be diagnosed using an OBD-II scanner to identify the underlying issue, which could range from a faulty sensor to more serious drivetrain or emissions problems. Given the vehicle’s age, also inspect the tyres for sidewall cracking or perishing, as the 2021 advisories noted front tyre damage and rear tyre wear, which may have been addressed but could resurface. Check the brake discs for grooving or lip formation at the edges, and ensure the calipers are not binding, as this can accelerate pad and disc wear. Verify the condition of the 12V battery, as original units often degrade after five to six years, and assess the health of all fluid systems, including coolant, brake fluid, and power steering fluid, which degrade over time regardless of mileage. Finally, review the service history to confirm that timing belt and water pump replacements, if applicable, have been carried out, as these are critical for long-term reliability.
