2017 Audi A4 1.4L Petrol · DU67 BYB

The 2017 Audi A4 presents a broadly stable mechanical picture at its most recent MOT on 4 November 2025, where it passed at 77,777 miles. That test flagged a knocking noise from the offside front suspension that the tester could not diagnose, alongside a nearside front service brake fluctuation and an illuminated multi-purpose brake warning light. None of these were fails, but they point to unresolved front-end and braking issues that a buyer should treat as live concerns rather than historical footnotes. The mileage progression is steady and consistent with typical use at roughly 8,600 miles per year. The car moved from 49,717 miles in May 2023 to 62,783 miles in May 2024, then to 74,471 miles in May 2025, and finally to 77,777 miles in November 2025. There are no alarming gaps or sudden jumps, suggesting regular use rather than long periods of standing, which reduces the likelihood of deterioration from inactivity such as seized brakes or perished rubber components. Suspension wear is the most persistent theme across the record. In May 2023 at 49,717 miles, both front upper suspension arm pins or bushes were worn, and the offside front shock absorber had a light oil misting. By May 2025 at 74,471 miles, the offside front upper suspension arm ball joint had developed slight play. Combined with the knocking noise noted in November 2025, this suggests the front suspension has been deteriorating progressively rather than being properly rectified. A buyer should have the front end inspected on a four-post lift, paying close attention to the upper and lower arm bushes, ball joints, and shock absorber condition. The braking system also warrants close attention. Front brake pads and discs were flagged as wearing thin and scored in May 2023, and the November 2025 test recorded a nearside front brake fluctuation alongside an active brake warning light. This combination suggests a potential issue with a sticking caliper, uneven pad wear, or a fault within the electronic braking system. A thorough inspection of all four corners, including caliper slide guides and the handbrake mechanism, is advisable before purchase.
