2017 Audi A4 2.0L Diesel · BW66 XAA

The 2017 Audi A4’s latest MOT test on 2026-09-01 reflects a critical re-evaluation of its roadworthiness following the previous failure in 2022-05-28, which highlighted a malfunctioning tyre pressure monitoring system (TPMS) under section 5.2.3(h). While the 2022 test was marked by a major failure, the subsequent tests from 2020 to 2022 have all passed, indicating either a resolution of the TPMS issue or a less critical underlying problem that did not reappear. However, the presence of advisories—particularly the repeated warnings about tyres worn close to legal limits on the offside front and rear—demonstrates a pattern of wear that suggests either aggressive driving or inadequate maintenance. The absence of further major failures in the intervening years suggests that while the vehicle’s structural and functional integrity remains largely intact, the tyre wear is a persistent concern that warrants immediate attention. The recorded mileage of 117,349 miles for a vehicle aged nine years represents a high annual usage rate of approximately 13,039 miles per annum, which is notably elevated for its age. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and fluid systems, as well as on the tyres themselves. The absence of significant mileage gaps—particularly in the last four years—implies sustained, heavy use, which can lead to accelerated degradation of suspension bushes, coil springs, and steering linkages. Additionally, prolonged exposure to static conditions (e.g., long periods parked without movement) can exacerbate issues such as brake disc corrosion, binding calipers, or fluid degradation, especially if fluids like brake fluid or coolant have not been serviced within the recommended intervals. The rapid mileage accumulation also raises concerns about potential neglect of routine servicing, which could have contributed to the TPMS failure observed in 2022. For a prospective buyer, the most critical inspection should focus on the tyre condition, given the repeated advisories from the DVSA records. Visually inspect the tyres for signs of uneven wear patterns, cracks, or bulges, and verify that the tread depth remains above the legal minimum of 1.6mm. On a test drive, listen for unusual noises from the tyres, such as excessive squealing or vibration, which may indicate misalignment or internal damage. The TPMS failure from 2022 suggests that the system may still be unreliable, so the buyer should confirm its functionality by checking the dashboard indicator and ensuring the tyre pressures match the manufacturer’s specifications. Additionally, the high mileage justifies a thorough examination of the suspension, including the inspection of coil springs, shock absorbers, and suspension bushes for signs of wear or failure, such as clunking noises when driving over bumps or uneven road surfaces. Beyond the immediate concerns, the buyer should also address the broader maintenance history suggested by the mileage. Given the vehicle’s age and usage profile, it is prudent to check the condition of the brake system, including the discs, pads, and calipers, for signs of corrosion or excessive heat damage, which can lead to binding or reduced braking efficiency. The brake fluid should be flushed and replaced according to Audi’s recommended service intervals, as standing fluid can absorb moisture and degrade over time, compromising brake performance. The engine oil and coolant should also be inspected for signs of contamination or sludge buildup, with a full service recommended if the vehicle has not been serviced within the last 12 months. Finally, the battery health should be assessed, as prolonged disuse or high mileage can lead to reduced capacity or corrosion, which may require replacement before the vehicle’s next major service. It is advisable to verify the presence of any service book stamps or maintenance records to ensure compliance with Audi’s recommended intervals for fluid changes, filter replacements, and other critical maintenance tasks.
