2008 Audi A5 2.7L Diesel · SN57 LVV

Recurring structural and chassis-related concerns define the mechanical history of this Audi A5, which most recently passed its MOT on 13 January 2026 following a dangerous failure for severely worn rear brake pads. While the vehicle successfully cleared its most recent inspection, the test record reveals a persistent pattern of degradation, particularly regarding the rear subframe and front suspension components. The transition from a dangerous brake failure to a pass within one week indicates that the immediate braking issue was rectified, yet the history of repeated subframe corrosion advisories and suspension wear suggests that the vehicle requires ongoing vigilance to maintain its roadworthiness. Accumulating 122,663 miles over eighteen years results in an average of approximately 6,815 miles per annum, a usage rate that is typical for a vehicle of this age. This consistent mileage suggests the car has been in regular operation rather than sitting idle for extended periods, which helps mitigate the risks associated with long-term storage such as seized calipers or fuel system degradation. However, this level of usage means that high-wear items like suspension bushings and drivetrain seals have reached a stage in their service life where they are prone to fatigue, as evidenced by the previous failures involving drive shaft boots and suspension arm wear. Prospective buyers should conduct a focused inspection of the rear subframe, which has been flagged for corrosion in three separate tests since 2022. During a test drive, listen for any metallic groaning or structural creaking from the rear end when traversing uneven surfaces, as this may indicate the progression of the noted corrosion. Furthermore, given the history of front suspension arm bush wear, pay close attention to the steering feel; any wandering, vibration through the steering wheel, or knocking noises when turning at low speeds could point to residual play in the front control arms that has not been fully addressed by previous repairs. The braking system warrants a thorough physical check, specifically regarding the parking brake mechanism, which was noted as having low efficiency and potential overheating symptoms during the 2026 failure. Ensure the electronic parking brake engages and releases smoothly without dragging, and check for any uneven heat or burning smells from the rear wheels after a short drive, which would indicate a binding caliper or sticking cable. Finally, inspect the front exhaust joining sleeve, as its history of heavy corrosion suggests it may be nearing the end of its functional life and could develop leaks, which would manifest as an audible exhaust blow or increased cabin noise under load.
