2009 Audi A6 2.0L Diesel · AM09 BFO

A clean DVSA record across the 2023 and 2024 test cycles, culminating in a pass on 18 August 2025 with no advisories or defects recorded, points to a vehicle maintaining consistent roadworthiness through its later years. The only blemish is a fail dated 11 August 2025, just one week before the pass, which with no defects listed suggests either an administrative refusal, a vehicle presented without insurance or in an untestable state, or a retest following a rectification rather than a genuine mechanical failure. Either way, the absence of structural corrosion notes, brake or suspension advisories, or recurring component wear across five tests demonstrates that nothing has been flagged by examiners as approaching the failure threshold, which is reassuring for a car of this vintage. The pattern reflects stable mechanical condition rather than a deteriorating one. Against an age of seventeen years, an annual mileage of roughly 5,700 miles is notably low, indicating either short-hop urban use, periods of inactivity, or a car that has covered relatively few long journeys. This usage profile reduces wear on major drivetrain and clutch components but increases the likelihood of corrosion seizing on items such as brake caliper slide pins, handbrake mechanisms, and suspension linkages. Standing periods of any significant duration also promote oil seals drying out, leading to misting around engine and gearbox gaskets, and can accelerate deterioration of rubber components like drive shaft boots and suspension bushes through perishing rather than mechanical fatigue. Given the absence of any flagged components, a prospective buyer should focus inspection on the areas most likely to affect an Audi A6 of this age and usage profile. During a test drive, listen for clonks or knocks from the front suspension over uneven roads, which would indicate worn upper or lower wishbone bushes or anti-roll bar links, and feel for any vagueness or knocking through the steering rack, a known wear point on this model. On a quiet stretch, apply the brakes firmly from speed and check for any judder through the pedal, which would suggest front disc warping common to lower-mileage cars used primarily for short journeys. Also verify the operation of the electronic parking brake, as caliper mechanisms on cars that have stood for extended periods frequently seize and prevent proper release or application. Finally, inspect the underside on a ramp for any surface rust on subframe and suspension components, even though none has been flagged, and check for oil residue around the cam chain cover and sump, as these are characteristic seepage points on the 2.0 and 2.7 litre engines commonly fitted to this generation. Examine the condition of the coolant expansion tank and the area beneath it for staining, as the plastic becomes brittle with age. The tyres should also be checked for flat-spotting or uneven inner shoulder wear, which is typical of a vehicle that has spent considerable time stationary or carried light loads consistently on one side. With no recorded advisories, the immediate MOT outlook appears favourable, but a thorough pre-purchase inspection by a specialist familiar with Audi B2-platform running gear would provide confidence that the low-mileage profile has not masked component deterioration.
