Expert verdict
Suspension: 1.3× the national share
Suspension accounts for 26.4% of everything recorded on the 2008 Audi Convertible, against 21.0% nationally — 5.4 points above. Ask for the front and rear suspension to be checked on a ramp before you buy — worn bushes and broken springs are cheap to look at and expensive to discover at test time.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 73.1% and this one manages 77.3% — 4.2 points ahead of what its age and mileage predict.
- Based on a small sample. 75 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 2008 Convertible
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 2008 Convertible
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 13.3% of tests
“registration plate lamp(s) inoperative in the case of multiple lamps or light sources”
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 suspension joints 6.7% of tests
“ball joint dust cover severely deteriorated”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
-
Check the coil springs 4.0% of tests
“coil spring fractured or broken”
Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
