2017 Audi A5 2.0L Petrol · E3 NEH

The 2017 Audi A5 presents a mixed maintenance picture, with a notable structural concern emerging in its most recent MOT that warrants careful attention. The March 2026 test at 73,270 miles passed, but the tester flagged corrosion on both nearside and offside rear lower coil spring mountings. While the corrosion was assessed as not seriously weakened at that point, this is a progressive condition. The record shows a clear trajectory: in March 2024 at 53,713 miles, the nearside rear coil spring was fractured and broken, causing a test failure. That spring was clearly replaced, yet by March 2026, corrosion has appeared on both rear mountings. This suggests the underlying cause of the original fracture, likely long-term corrosion weakening the mounting point, was not fully addressed. The trend for this specific structural area is worsening, moving from a single broken spring to corrosion on both sides of the rear suspension. The mileage accumulation is unremarkable and consistent with typical use. The car covered approximately 9,379 miles between the March 2023 test at 46,213 miles and the March 2025 test at 63,891 miles, and roughly 9,379 miles again in the following year to the March 2026 test at 73,270 miles. This steady annual rate of around 9,400 miles indicates regular use without significant periods of standing or sudden high-mileage accumulation. The MOT record itself is complete and annual, with no gaps, providing a reliable service history. The clean passes in 2023 and 2025, with zero defects, contrast sharply with the recurring rear suspension issues bookending that period. A buyer must inspect the rear suspension with particular focus. The rear coil spring mountings and the condition of the coil springs themselves require close examination for any signs of cracking, advanced corrosion, or previous welding repairs. Given the history of a fractured spring and subsequent corrosion advisories, the structural integrity of the rear subframe and mounting points should be verified. The rear braking system also appears to have needed attention, with advisories for thin brake pads recorded in March 2024. While this was rectified for the subsequent test, the condition of the rear brake discs and pads should be checked for uneven wear, which can indicate sticking calipers or slider pin issues. Beyond these flagged items, a thorough underbody inspection is advisable to assess the extent of any corrosion on other suspension components, the exhaust system, and the vehicle's structural seams, as the pattern suggests this car may be susceptible to corrosion in critical load-bearing areas.
