2007 Audi A6 3.0L Diesel · LR07 UDM

A clear pattern of front suspension wear, rear corrosion, and aged lamp units emerges from this 2007 Audi A6's MOT record, with the most recent assessment on 25 November 2025 resulting in a pass accompanied by advisories for light oil misting on both front shock absorbers and corroded yet non-critical rear suspension components. The earlier test on 13 November 2025 had recorded the same shock absorber and rear suspension advisories, but additionally failed on a dangerously loose front undertray likely to become detached, an untestable nearside front headlamp aim, and a seriously defective nearside front headlamp lens. The undertray issue was resolved prior to the pass, but the headlamp defects represent a recurring theme: by November 2024 both headlamp lenses were already flagged as slightly affecting light output, and the nearside registration lamp was noted for reduced output, suggesting progressive degradation of exterior lighting condition. Across consecutive 2024 entries the same set of advisories recurs, indicating that suspension arm bushes, brake disc condition, and an oil leak were known issues that remained unattended between tests rather than being rectified. With 135,497 miles recorded over approximately nineteen years, annual mileage averages around 7,131 miles, which sits broadly in line with typical usage for a vehicle of this age and prevents the usual concerns associated with either very low or exceptionally high accumulation. The mileage progression between tests appears consistent and proportionate to the elapsed time, showing no sudden jumps that would suggest tow-mileage discrepancies or extended periods off the road with irregular use. For a petrol or diesel A6 of this vintage, this level of use typically translates to moderate wear on major drivetrain components while still requiring attention to age-related rubber, bushings, and corrosion-prone underbody items, all of which are reflected in the recorded advisories. A prospective buyer should treat the front shock absorber oil misting as an early warning rather than a current failure, but recognise that misting on both units at this age often progresses to a more serious leak within the next twelve to twenty-four months, particularly under heavy load or high-speed driving. On a test drive, listen for any clonking or knocking from the front struts over uneven surfaces, and pay close attention to body control through corners and over dips, where tired dampers typically show excessive bounce or a slow recovery. The worn front suspension arm pins and bushes flagged in 2024 warrant a careful inspection for any knocking or slack when the steering is loaded, such as during tight manoeuvres or when traversing speed humps, as these components directly influence steering precision and tyre wear patterns. The offside front brake disc scored inboard condition should be checked by lifting the wheel to feel for a heavy lip on the disc edge and by testing for brake shudder under firm application, while an overall brake pedal feel that is firm and consistent without sponginess or pulling to one side will confirm the hydraulic system remains sound. The corrosion noted on the rear suspension components, although not categorised as serious weakening, is characteristic of nineteen-year-old underbody surfaces and warrants a physical inspection on a ramp for any deeper localised corrosion around mounting points, subframe seams, and brake pipe runs that could escalate if left untreated. The oil leak advisory from the same period deserves identification of its source, whether from the valve cover gasket, sump area, or turbo oil feed lines depending on engine variant, as leaving an active leak unresolved risks accelerating component degradation. The headlamp lens condition, which contributed to the November 2025 failure, should be examined directly to confirm whether polishing or replacement has restored clarity, as badly hazed polycarbonate lenses significantly reduce night-time visibility and will fail the next test if not rectified. Finally, ensure the undertray fix from the 2025 failure is secure and all retaining clips are present, as a flapping undertray at speed presents both a safety hazard and an immediate MOT failure risk.
