2005 Audi S4 4.2L Petrol · KU55 EYG

The vehicle presents a consistent history of passing inspections, with the most recent test in March 2025 at 125,141 miles resulting in no recorded defects. This indicates that the previous owner addressed the mechanical issues identified in prior tests. However, the failure in March 2024 at 123,170 miles highlights a period of neglect regarding exhaust carbon monoxide levels, a perished front tyre, and worn front brake discs. The fact that the vehicle passed again just two days after that failure suggests a reactive maintenance approach where repairs were performed abruptly rather than following a preventative schedule. At 125,141 miles over 21 years, this S4 averages approximately 6,000 miles per annum, which is significantly lower than the national average for a performance car. This low mileage often leads to the degradation of rubber-based components, which is evidenced by the advisory in December 2023 at 119,818 miles where both the nearside and offside front tyres were noted as being near the legal limit and worn on edges. Buyers should inspect for dry rot in suspension bushes, tyres, and engine seals, as long-term standing can cause materials to perish regardless of the low odometer reading. The braking system shows clear evidence of wear, with the front discs being flagged as worn in both the March 2024 failure and the subsequent pass. While the vehicle passed the 2025 test without defects, the recurring mention of brake components suggests the system may require frequent monitoring for thinning or binding. Given the age of the vehicle, a thorough inspection of the chassis for structural corrosion at the mounting points is essential, as the MOT record does not explicitly detail the state of the underbody rust issues common to this generation of Audi model.
