2010 Audi Q5 2.0L Diesel · PL10 DPE

The most recent MOT test results, conducted on 2025-04-23, show a mixed outcome with both passing and failing grades, indicating a pattern of recurring issues rather than a consistent improvement. The vehicle failed in 2025 on two separate occasions due to a persistent Engine Management System (EMS) fault, specifically a malfunctioning MIL light—this suggests a persistent electrical or sensor issue that has not been resolved, which could lead to further complications if ignored. While there were passing MOTs in 2024 and earlier, the presence of multiple advisories—particularly around tyre wear and suspension components—demonstrates a trend of wear-related defects that have not been fully addressed. The failure to achieve a clean pass despite previous compliance highlights the need for thorough mechanical attention before purchase. The lack of recorded mileage data makes it impossible to accurately assess annual usage, but the MOT history suggests a vehicle that has been subjected to variable conditions. The gaps between MOTs—such as the 18-month interval between 2024 and 2025—could imply either infrequent use or a history of neglect, both of which may have accelerated wear. The presence of a near-side front drive shaft CV joint boot failure in 2025 indicates significant exposure to road debris or improper maintenance, which can lead to accelerated joint wear and eventual failure if not serviced promptly. Additionally, the repeated tyre advisories, particularly around edge wear and cuts, suggest either aggressive driving or poor alignment, both of which can cause premature tyre degradation and compromise handling. For a prospective buyer, this vehicle presents several critical areas of concern that must be addressed before purchase. The Engine Management System fault is the most pressing issue, as persistent MIL indications can lead to reduced fuel efficiency, potential catalytic converter damage, and eventual engine performance degradation. A thorough inspection should include a diagnostic scan to confirm the exact fault code and whether it stems from a faulty sensor, wiring issue, or more serious engine component failure. The suspension advisories, particularly the perished top arm bushes, are a major red flag—their failure can lead to excessive body roll, uneven tyre wear, and even structural instability if left unaddressed. During a test drive, listen for clunking noises from the front suspension when driving over bumps, and check for uneven tyre wear patterns, which may indicate misalignment or suspension misalignment. The tyre advisories, including multiple instances of edge wear and cuts, warrant immediate attention. Edge wear typically results from underinflation, incorrect tyre pressure, or poor alignment, while cuts can indicate road debris damage or excessive flexing. Inspect the tyres for signs of internal cord damage or separation, which could lead to sudden failure. The near-side front drive shaft CV joint failure is another critical issue—this joint is a high-stress component, and its boot failure means it is no longer effectively sealed against contaminants. A replacement is essential, and the buyer should verify the joint’s condition and ensure the boot is properly installed and sealed. Finally, given the vehicle’s age, the buyer should also check for signs of tyre sidewall cracking or perishing, which can compromise structural integrity over time, and inspect the battery and electrical system for signs of corrosion or poor connections, as the MIL fault may also indicate broader electrical issues. If the vehicle has been stored for extended periods, check for standing corrosion on the chassis, brake components, and exhaust system, as prolonged idleness can accelerate rust formation.
