The 2008 Audi A6 diesel passes its MOT at 79.2%, virtually matching the UK average of 80%, but here's the real concern: 42.3% of these cars have recorded a dangerous defect at some point, which is substantially higher than typical and suggests structural or safety issues that demand careful inspection before purchase. Petrol versions fare marginally better at 81% pass rate, though the diesel dominance in this cohort (95% of analysed vehicles) means your options are limited if you want to avoid that higher risk profile.

With a median mileage of 107,322 miles for a 16-year-old car, these A6s are running roughly in line with age expectations, but the average of 3.38 failures per test and notably high advisory count of 19.7 items indicate persistent wear and maintenance demands. Before buying, insist on a pre-purchase inspection that specifically flags suspension, brake, and electrical systems—the typical weak points flagged in advisories—and budget accordingly for repairs that are likely imminent.

The 2008 Audi A6 has a decent first-time pass rate (79.3%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.
🔧 Expect consumable spend. An average of 19.7 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 11,305 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.

Watch for defects — worth knowing

What tends to go wrong

Across 11,305 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Other issues 66.6%
Under-trays fitted obscuring some underside components · Engine covers fitted obscuring some components in the engine bay · Oil leak, but not excessive · …
Tyre wear 61.3%
Nearside Front Tyre worn close to the legal limit · Offside Front Tyre worn close to the legal limit · Nearside Front Tyre worn close to legal limit/worn on edge · …
Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.
Brake wear 60.7%
Rear Brake pad(s) wearing thin
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Suspension & steering 20.3%
