2012 Audi Q3 2.0L Diesel · LL62 RNA

The most recent MOT test on the 2012 Audi Q3 occurred on 2023-06-24, resulting in a passing outcome despite the presence of several advisories. This follows a pattern of fluctuating results, with the vehicle failing in 2019 due to critical engine issues and minor structural defects, before returning to passing status in 2020 and 2021. The recurring advisories on tyre wear and brake disc corrosion suggest a maintenance trend that has not fully resolved underlying wear and tear concerns, though the absence of major failures in the last three years indicates a period of relative stability. The presence of persistent low-level defects, particularly the brake disc corrosion and tyre edge wear, points to either suboptimal maintenance practices or inherent wear progression that has not been adequately addressed, warranting careful scrutiny during inspection. The vehicle’s recorded mileage of 74,132 miles at the time of this assessment represents a notably low annual usage rate of approximately 5,295 miles per year, which is unusually low for a 14-year-old car. Such low mileage often correlates with periods of prolonged inactivity, where components like brakes, suspension, and tyres can degrade more rapidly due to standing corrosion and fluid degradation. The absence of higher mileage accumulation over the past few years suggests either deliberate underuse or significant downtime, which may have exacerbated wear issues such as brake pad thinning and tyre edge wear observed in the MOT history. However, this pattern also raises concerns about potential neglect in fluid servicing and lubrication, as standing vehicles are particularly susceptible to corrosion in brake systems, suspension components, and electrical connections. For a prospective buyer, the most critical areas to inspect during a physical examination of this Audi Q3 include the brake system, suspension, and tyres. The advisories on brake disc corrosion all round indicate that the discs may be severely pitted or bonded to the pads, leading to reduced braking performance and potential failure if not addressed. On a test drive, listen for uneven braking, a grinding noise during deceleration, or a shudder that could signal warped or corroded discs. Inspect the brake pads for complete wear—if they are thin or missing entirely, this is a major safety risk that should be rectified immediately. Additionally, check for any fluid leaks under the vehicle, particularly around the brake master cylinder and calipers, as standing corrosion can compromise hydraulic integrity. The tyres should be thoroughly examined for sidewall perishing, which is common in low-mileage vehicles that have stood for extended periods, as this can compromise structural integrity and lead to sudden blowouts. Look for cracks or delamination in the sidewalls, and measure the tread depth to ensure it remains above the legal minimum. The offside rear tyre showed signs of cracking in the tread during the 2019 MOT, so this area should be scrutinised for further deterioration. The suspension should be checked for signs of wear in bushes, coil springs, and struts, as standing vehicles can cause these components to stiffen or fail prematurely. Finally, given the engine MIL failures in 2019, verify that the vehicle’s electrical system and wiring are intact, and that the battery is fully charged and healthy, as prolonged inactivity can lead to corrosion in terminals and reduced cranking power. Time-based servicing of fluids such as coolant, brake fluid, and differential oil should also be confirmed, as fluids degrade even when the vehicle is not in use. If the service history is sparse, consider a thorough fluid exchange and inspection of critical components like the engine oil filter and transmission fluid.
