2010 Audi Q5 2.0L Diesel · SW60 CEN

Structural corrosion and persistent rear-axle wear form the primary mechanical narrative of this Audi Q5, punctuated by recent component failures that demand careful scrutiny. On September 8, 2026, the vehicle secured a pass after initially failing its MOT due to a dangerously thin nearside rear brake pad measuring under 1.5 millimetres alongside a binding service brake. While that immediate safety defect was rectified to clear the test, the inspection also flagged a corroded rear subframe and a corroded offside rear coil spring, signaling that foundational metal and suspension components are entering a phase of advanced environmental degradation. This follows an earlier failure in 2022 caused by a fractured nearside front coil spring, illustrating that the vehicle's heavy suspension components and braking hardware are regular wear points requiring ongoing financial outlay. Accumulating 122,045 miles across its sixteen-year lifespan yields an average of roughly 7,628 miles driven annually, representing a typical and consistent usage rate for a diesel SUV of this class. The testing cadence shows no prolonged periods of statutory off-road storage or unrecorded gaps, with annual MOTs conducted reliably every autumn from 2021 through 2026. This steady accumulation pattern means the drivetrain has been in continuous, regular operation rather than suffering from the mechanical seizures often associated with extended inactivity, though the steady mileage has naturally accelerated the wear on high-mass components like suspension bushes, subframe assemblies, and brake discs. Prospective buyers must prioritize a thorough physical inspection of the chassis, specifically examining the rear subframe to gauge the severity of the rust noted on the latest test certificate, and checking whether the offside rear coil spring shows deep flaking or structural compromise. During a static walk-around and test drive, listen carefully for metallic crunches, groans, or clunks from the rear axle when cornering or traversing speed humps, which would indicate degraded spring coils or tired subframe mountings. Additionally, check the operation of the rear brakes for any lingering drag, pulling, or uneven disc scoring, as the history of a binding nearside rear service brake requires verifying that the calipers, sliding pins, and handbrake mechanisms release fully without generating excessive localized heat. Further attention should be given to the front axle and steering geometry, keeping in mind the historical advisory for a worn offside front suspension arm bush and front brake disc pitting recorded during the 2022 test cycle. On the test drive, pay close attention to steering response and straight-line tracking, ensuring the vehicle does not wander or exhibit vibration through the steering wheel under braking, which would point to warped front discs or failing control arm bushes. Reviewing the physical service invoices alongside these MOT advisory items will be essential to determine if components such as the brake pads, discs, and suspension arms have been replaced wholesale or merely patched up to pass successive annual tests.
