Expert verdict
Brakes: 1.6× the national share
Brakes make up 33.0% of everything recorded on the 2015 Audi S1, against 20.9% nationally — 12.1 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.
- When it fails, it costs. Only 8% 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. 76 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 2015 S1
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 2015 S1
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 coil springs 2.6% 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.
-
Check the suspension joints 2.6% of tests
“pins and bushes pin or bush excessively worn”
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 exhaust and emissions 1.3% of tests
“catalyst emissions hydrocarbon content after 2nd fast idle exceeds default limits”
Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
What it costs to get a 2015 S1 through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £33–£95 — and 8% of those repairs are parts that cost under £30.

What testers noted without failing the car
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.
| Recorded item | Severity | Tests | Est. cost |
|---|---|---|---|
| Brake discs in such a condition that it is seriously weakened Brakes | Advisory | 21.1% | £45–110 |
| Pins and bushes pin or bush excessively worn Suspension | Advisory | 14.5% | £40–150 |
| Has a tear, caused by separation or partial failure of its structure Tyres | Advisory | 13.2% | £45–95 |
| Tread depth below requirements of 1.6mm Tyres | Advisory | 9.2% | £45–95 |
