2017 Audi A3 1.6L Diesel · BF67 YCZ

The 2017 Audi A3 presents a mixed maintenance picture that has deteriorated notably in its most recent test cycle. The November 2025 pass at 75,950 miles was clean on safety-critical grounds, yet it carried seven separate advisories, the highest density of defects in this record. That contrasts sharply with the preceding two years of testing, where the car sailed through with zero or minimal advisories. The trend is therefore worsening at the point of sale, not because of a single catastrophic fault, but because multiple consumable and wear items have reached replacement thresholds simultaneously without evidence they have been addressed since November 2025. The mileage accumulation of roughly 8,439 miles per year sits squarely within the UK average for a vehicle of this age, so there is no suspicion of either extreme low use or punishing high-mileage abuse. The jump from 66,152 miles in October 2024 to 75,950 miles by November 2025 represents about 9,800 miles in thirteen months, a modest uptick but nothing alarming. What matters more is that the car appears to have sat at 75,950 miles for at least seven months by today's date of June 2026, with no fresh MOT on file, leaving a gap in oversight that a buyer should probe. The recurring theme across the last two tests is brake disc wear. In November 2025, all four brake discs were flagged as worn, though not excessively, while the October 2022 failure had already highlighted rear brake linings worn below 1.5 mm at 53,689 miles. That the discs are now drawing attention again at nearly 76,000 miles suggests either the braking components have not been renewed since that earlier failure or a set of replacement discs has simply reached the end of its service life. A buyer should have a workshop measure disc thickness and pad depth on all corners before committing, paying particular attention to the rears given the historical failure pattern. Tyre condition is the other persistent weak spot. The November 2025 test flagged both front tyres worn to the legal limit on inner and outer edges, an offside rear tyre with multiple cuts, and a nearside rear tyre showing cracking or perishing. Uneven edge wear on the fronts points toward tracking or suspension bush wear rather than simple neglect, and the aged rear tyres raise questions about how long they have been left in that state. The damaged windscreen, noted as far back as October 2024, remains unrepaired and should be checked against current MOT standards to determine whether it now constitutes a fail. A pre-purchase inspection should include a four-wheel alignment check, close visual inspection of all tyre sidewalls, and confirmation of whether the windscreen has been replaced or repaired since the last test.
