2014 Audi A6 2.0L Diesel · CK14 FEH

A serious brake performance issue emerged in late 2025 when the car failed an MOT on 4 November 2025 for service‑brake efficiency, parking‑brake efficiency and rear‑brake imbalance, all recorded as major failures. The subsequent MOTs on 6 November 2025 and 5 September 2026 passed without defects, indicating that the brake system was likely rectified and is currently meeting legal standards. Apart from a 2024 advisory about thin rear‑brake linings and a 2020 advisory on front‑tyre wear, the record contains no further defects or recurring advisories. At 105,353 mi recorded over a twelve‑year lifespan, the vehicle averages roughly 8,800 mi per year, which sits comfortably within normal UK usage patterns. The mileage progression appears steady, with no abrupt spikes or prolonged gaps between tests, suggesting the car has not been subjected to unusually high short‑term loads. Mechanically, this moderate annual accumulation should translate to typical wear on consumables such as brake pads, tyres and suspension components, without the accelerated degradation seen on high‑mileage units. When inspecting the brakes, verify that the pedal applies firm and progressive pressure with a short travel before the vehicle begins to decelerate; any sponginess, excessive pedal travel or a pulsating feel could indicate residual hydraulic issues or uneven pad wear. Test the parking brake for a solid hold on a gentle incline and listen for any uneven squeal or grinding that might betray uneven rear‑brake wear. Examine the rear‑brake discs and pads for uneven thickness or scoring, and confirm that the parking‑brake mechanism engages cleanly without excessive slack. The front‑tyre advisory from 2020 warrants a thorough visual and tactile tyre check. Measure tread depth across the width of each tyre; depths below 1.6 mm or signs of edge‑wear suggest the tyres are approaching the legal limit and may need replacement. While driving, be alert for vibration or a pulling tendency, especially at higher speeds, which could indicate tyre imbalance, mis‑alignment or worn suspension bushes. A brief inspection of the suspension for any play in the control arms, worn bushings or leaking shock absorbers will complement the brake and tyre assessment, ensuring the car’s overall roadworthiness before purchase.
