2015 Audi A5 2.0L Diesel · OV15 LCE

The most recent MOT, carried out on 2 October 2025, was a pass but recorded two advisories – front brake pads approaching the minimum thickness and a marginal wear on the off‑side front lower suspension arm pin or bush. Earlier in the series the vehicle failed in October 2024 due to an excessively binding off‑side front service brake and in October 2023 for a dangerous tyre defect, yet it subsequently passed in both 2023 and 2024 with only minor advisory notes. This pattern shows that the major brake‑binding fault has been remedied, and the current trend is stabilising, although the front‑brake wear items remain a concern that will need attention before they become safety‑critical. At 50,535 miles on a 2015 model the car averages roughly 4,600 miles per year, which is well below the typical usage for a vehicle of this age. The low annual mileage suggests periods of light use or extended storage, which can be as detrimental as high mileage in terms of corrosion, fluid ageing and rubber degradation. There is no evidence of a sudden mileage surge that would indicate hidden mileage, but the modest total does mean that wear on high‑stress components such as the suspension bushings, brake discs and tyres may be more a function of calendar age than distance travelled. Prospective buyers should give the front braking system the highest priority. Verify the remaining pad thickness on both sides – pads thinner than 3 mm are approaching the legal limit – and inspect the discs for scoring, glazing or excessive thinning, especially on the off‑side where a binding condition was previously recorded. During a test drive feel for any pedal pulsation, shudder or a pull to one side when applying the brakes, and listen for metal‑on‑metal squeal that could indicate warped discs. The advisory on the front lower suspension arm pin or bush warrants a hands‑on check for any play in the wheel when rocked at the 12 o’clock position and for clunking noises over bumps, which would signal that the bush may need replacement. The tyre history is concerning: one tyre was found with exposed ply and the opposite front tyre was close to the legal tread limit. All four tyres should be examined for tread depth, side‑wall cracking and age (DOT code), and it is advisable to replace any tyre older than six years regardless of tread, as rubber perishing can lead to sudden failure. Given the vehicle’s age and low mileage, a thorough age‑related inspection is essential. Test the 12‑volt battery for voltage under load and check for any signs of sulfation or leaking electrolyte; a battery older than four years often requires replacement. Examine the coolant, brake fluid and engine oil for discoloration or moisture – these fluids degrade over time even when the car is not driven and should be changed at least every two years. Inspect the under‑carriage for rust, especially around the wheel arches, suspension mounting points and exhaust system, as standing periods accelerate corrosion. Confirm that the service book records regular oil changes, timing‑chain or belt service (the 2015 A5 typically uses a timing chain but any related service intervals should be documented), and that any previous brake or suspension work has been carried out by a reputable workshop. Addressing these points will give a clear picture of the car’s current roadworthiness and the likely cost of bringing it to a fully reliable condition.
