2015 Audi A5 3.0L Petrol · SW65 EJO

The most recent MOT test conducted in October 2025 resulted in a pass, but the vehicle's maintenance trend is concerning as it shows a progressive deterioration in consumable items. While the car has avoided outright failures, the frequency and nature of the advisories have increased significantly over the last three years. We have moved from minor cosmetic issues and tyre cuts to serious concerns regarding tyre tread depth, uneven wear patterns, and tyre perishing. This shift suggests that while the vehicle is being kept roadworthy in a legal sense, the preventative maintenance regarding tyres and braking components is being deferred, which may indicate a general lack of proactive mechanical attention. The recorded mileage of 47,576 miles over an eleven-year period is exceptionally low, averaging approximately 4,325 miles per year. While low mileage is often viewed as a benefit, in this specific context, it likely indicates the vehicle has spent significant periods stationary or has been used only for very short, infrequent trips. Such usage patterns can be detrimental to a vehicle of this age. Low annual mileage often leads to accelerated degradation of rubber components due to lack of movement, potential moisture accumulation in the exhaust and braking systems, and the degradation of fluids that rely on thermal cycling to remain effective. You should verify the service history to ensure that oil and fluid changes have been performed based on time intervals rather than just mileage. A critical area for your inspection is the tyre condition and the underlying cause of the uneven wear. The recent advisories for tyres wearing on the inner edges and being close to the legal limit suggest potential issues with wheel alignment, worn suspension bushes, or damaged control arms. During your test drive, listen closely for any clunking or knocking sounds when traversing uneven surfaces, which could indicate worn suspension components. Furthermore, check for any steering pull or vibration at motorway speeds, as the history of sidewall damage and uneven tread suggests the geometry may be out of specification. Given the recurring advisories for tyre perishing and cracking, you must physically inspect the sidewalls for deep cracks, as the rubber may be becoming brittle from age regardless of the remaining tread depth. Beyond the tyres, you should pay close attention to the braking system and the electrical health of the vehicle. The 2023 advisory regarding thin brake pads indicates that the braking components are nearing the end of their service life, so check for any pulsation through the brake pedal or squealing noises during deceleration. The recent TPMS light advisory should be investigated to ensure it is a simple sensor issue rather than a symptom of a leak or a more complex electrical fault. Because the car has been driven so little, also inspect the underside for signs of surface corrosion on the exhaust and brake discs, which can occur from standing. Finally, check the 12V battery health, as low-use vehicles frequently suffer from battery sulphation and may require replacement if they have not been regularly maintained or charged.
