2007 Audi A3 1.6L Petrol · RE07 AXT

The most recent MOT, conducted on 17 March 2026, recorded a pass for the overall inspection but flagged a failure on the exhaust hydrocarbon content after the second fast idle, indicating the emissions system is currently out of specification. Earlier in the same session the vehicle was listed as passed with no other defects, suggesting the majority of the safety items were satisfactory. Looking back through the last three years the trend is mixed: the 2024 test was clean, the 2025 test highlighted a serious front‑coil‑spring fracture together with corrosion on the opposite side, and the 2026 test now adds an emissions failure. In other words, the vehicle’s condition has moved from a clean bill of health to a series of emerging mechanical and environmental concerns, signalling a deterioration rather than an improvement. At 150,990 mi on a 2007 model the average annual mileage works out at roughly 7,950 mi per year, which is broadly typical for a car of this age. The mileage figure does not suggest any periods of extreme use or unusually low utilisation that might mask hidden wear, but the cumulative distance does mean that wear items such as suspension bushings, engine mounts, brake discs and drivetrain components will have been subject to considerable life‑cycle stress. The front‑coil‑spring fracture recorded in 2025 is a red flag for the front suspension’s structural integrity, and the accompanying corrosion on the opposite spring points to exposure to moisture and possible rust ingress in the sub‑frame area. Prospective buyers should give the front suspension a thorough examination. Visually inspect both front coil springs for cracks, corrosion, or deformation, and check the top mounts for any signs of oil leakage or looseness. During a low‑speed test drive listen for any clunking or knocking when negotiating bumps, and feel for any wandering or pulling to one side that could indicate a broken spring or worn bushings. The exhaust emissions failure means the catalytic converter, oxygen sensors, and exhaust manifold should be examined for leaks, blockage, or excessive soot buildup; a failing catalyst will often produce a noticeable sulphur or rotten‑egg smell and may cause a loss of power under acceleration. A diagnostic scan for fault codes related to the exhaust system would be prudent before committing to purchase. Given the vehicle’s age, independent of the recorded defects, it is sensible to check time‑related items that are not mileage‑dependent. Examine the tyre sidewalls for cracking, dry rot or weather‑related perishing, especially if the tyres have been on the car for several years. Test the 12‑volt battery for cranking voltage and check for any corrosion on the terminals, as standing periods can reduce capacity. Inspect the brake discs for surface rust, scoring or glazing, and verify that the calipers move freely without sticking, as corrosion can cause uneven pad wear. Finally, confirm that the service book shows regular oil and filter changes, coolant flushes and timing‑belt (or chain) service at the manufacturer’s intervals; fluid degradation over time can lead to premature wear of internal engine components even if the mileage appears moderate.
