2017 Audi A3 1.4L Petrol · B15 FBK

Persistent tyre wear and the emergence of structural corrosion on the rear suspension linkages define the current mechanical profile of this Audi A3, which secured a pass on 11 May 2026 despite these noted defects. While the vehicle maintained a clean record for the majority of its life, the recent consecutive advisories regarding the nearside rear tyre suggest a recurring alignment or tracking issue that has not been rectified. The appearance of corrosion on the rear lower suspension arms, while currently categorized as not seriously weakened, marks a shift from the previous years of defect-free testing and requires monitoring as the vehicle ages. Accumulating 34,866 miles over nine years results in an average of approximately 3,874 miles per annum, a figure significantly below the national average for a vehicle of this class. This low-mileage profile often points to a pattern of short, infrequent journeys, which can prevent the engine and exhaust system from reaching optimal operating temperatures consistently. Prospective buyers should be aware that such usage can lead to accelerated internal condensation within the exhaust system and may result in premature stiffening of rubber components and seals that are designed to remain supple through regular, long-distance heat cycles. During the test drive, the priority must be to investigate the suspension and handling characteristics, specifically focusing on the rear end where the corrosion was flagged. Listen for any metallic clunks, creaks, or knocking sounds when traversing speed bumps or uneven road surfaces, as these are primary indicators of failing suspension bushes or compromised mounting points. Furthermore, ensure the vehicle tracks straight on a flat road surface without pulling to the left or right, as the repeated tyre wear advisories could indicate that the rear geometry is out of alignment, which may lead to uneven handling or premature wear on new tyres if not corrected by a professional four-wheel alignment. Beyond the suspension, the tyre wear noted in both the 2025 and 2026 inspections warrants a thorough physical check of the tread depth and pattern across the entire width of the rear tyres. If the wear is concentrated on the inner or outer edges, it confirms that the suspension geometry requires adjustment. Given the low annual mileage, verify that there is no evidence of binding brakes or seized calipers, which can occur when a vehicle sits stationary for extended periods; check for any dragging sensation or excessive heat radiating from the wheels after a short drive, and ensure the handbrake engages firmly and releases without resistance.
