Expert verdict
Advisories: 4.3× the national share
Advisories make up 18.0% of everything recorded on the 2020 Audi Q8 Sln, against 4.2% nationally — 13.8 points above. Tyres are still the single largest share at 31.1%, but at 19.8% nationally that one is ordinary. Most of what testers record here is advisory — worth reading, not worth walking away from on its own.
- When it fails, it costs. Only 31% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.
- Based on a small sample. 99 tests back this page. That is enough to publish and to index, not enough to treat the decimal places as precise — read the pattern, not the second digit.

What fails a 2020 Q8 Sln
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2020 Q8 Sln
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the lights 3.0% of tests
“malfunction indicator lamp inoperative or indicates a malfunction”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
-
Check the number plates 2.0% of tests
“registration plates does not conform to the specified requirements”
Check both plates are present, legible and correctly spaced, with the postcode of the supplier and the BS AU 145e mark. A private plate in the wrong style is a fail before the car is even looked at.
-
Check the brakes 1.0% of tests
“brake discs significantly and obviously worn”
Look through the spokes of each wheel at the pad — less than 3mm of friction material, or a lip on the disc edge, is the usual failure. Check the handbrake holds on a slope with a few clicks, not at the top of its travel.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
