What fails a Vauxhall Astra MOT
Each bar is the share of failed Vauxhall Astra tests with that defect. Where we can compare it with cars of the same registration years, the marker shows what an average car of those ages records (11 of the 12 items below).
Most common reasons for failure
A test can fail for more than one defect, so shares add up to more than 100%.
| Defect | Share of failed tests |
|---|---|
| Coil spring: fractured or broken Suspension | 16.7% |
| Brake pads: less than 1.5 mm thick Brakes | 8.6% |
| Position lamp: not working Lamps, reflectors and electrical equipment | 8.1% |
| Tyres: tread depth below requirements of 1.6mm Tyres | 7.6% |
| Malfunction indicator lamp: inoperative or indicates a malfunction Noise, emissions and leaks | 7.5% |
| Stop lamp: not working Lamps, reflectors and electrical equipment | 7.0% |
| Washers: provides insufficient washer liquid Visibility | 6.0% |
| Exhaust system: major leak of exhaust gases Body, chassis, structure | 6.0% |
| Headlamp aim: projected beam image is obviously incorrect Lamps, reflectors and electrical equipment | 5.9% |
| Parking brake efficiency below requirements Brakes | 5.3% |
| Headlamp: not working on dipped beam Lamps, reflectors and electrical equipment | 5.3% |
| Tyre pressure monitoring system: malfunctioning or obviously inoperative Tyres | 4.7% |

Broken coil spring
16.7% of failures 9.7% expected 1.7 times as often
A broken suspension spring, which usually snaps in the bottom coil and often fails on both sides within a year.
Look at each corner for a sagging ride height, and listen for a knock over speed bumps.
-
Worn brake pads
8.6% of failures 6.0% expected somewhat more often
Friction material worn under 1.5mm, thinner than the point most manufacturers call the limit.
Look through the wheel spokes at the pad against the disc; wear indicators squeal before they get this far.
-
Sidelight out
8.1% of failures 9.6% expected somewhat less often
A sidelight, also called a position lamp, not working. It marks the width of the car at night.
Walk round the car with the lights on and the hazards going; these are the cheapest failures to avoid.
-
Tyre worn below the legal limit
7.6% of failures 7.8% expected about as expected
A tyre worn past the 1.6mm legal minimum across the middle three quarters of the tread.
A 20p coin in the main grooves: if the outer band of the coin is visible, the tyre is close to the limit.
-
Engine management light on
7.5% of failures 5.4% expected somewhat more often
The engine management light is on, or has been disconnected. Either fails the test.
A cheap code reader on the diagnostic socket will say what the car has stored before you pay for a test.
-
Brake light out
7.0% of failures 7.2% expected about as expected
A brake light not working, from a bulb, a poor earth, or the switch on the pedal.
Reverse up to a wall or window at dusk and press the pedal to see all three lamps light.
Which parts of the car fail
Lamps, reflectors and electrical equipment is the area that most often fails a Vauxhall Astra, on 38.1% of failed tests. The widest gap against cars of the same registration years is noise, emissions and leaks, on 15.9% against 11.8% expected.

What testers warn about
61.7% of Vauxhall Astra tests ended with at least one advisory: a fault the tester found that did not fail the test. On Vauxhall Astras, these are the items to ask about on a car you are viewing, because they are what the last tester expected to go next.
Most common advisories
Share of all tests, passes included.
| Advisory | Share of tests |
|---|---|
| Tread depth: worn close to legal limit or worn on edge Tyres | 19.3% |
| Engine oil leak, but not excessive Noise, emissions and leaks | 15.5% |
| Tyres: slightly damaged or cracking or perishing Tyres | 12.7% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 12.2% |
| Brake pads: wearing thin Brakes | 9.3% |
| Coil spring: corroded Suspension | 7.2% |
| Exhaust system: minor leak of exhaust gases Body, chassis, structure | 6.0% |
| Rigid brake pipes: corroded, covered in grease or other material Brakes | 5.8% |
| Registration plates: deteriorated but not likely to be misread Identification of the vehicle | 4.4% |
| Suspension arms: pin or bush worn but not resulting in excessive movement Suspension | 4.0% |
| Brake discs: worn, but not excessively Brakes | 3.6% |
| Shock absorbers: light misting of oil Suspension | 3.2% |

What changes as a Vauxhall Astra gets older
A 2022 Vauxhall Astra failed 10.7% of its MOT tests in 2025; a 2001 one failed 42.5%. What fails changes as much as how often, and these are the two years themselves rather than an average across them.
2022 Vauxhall Astra 10.7% failed, from 2,896 tests
- Cut tyre 23.0%
- Washers that do not work 12.9%
- Worn brake pads 12.3%
- Tyre worn through to the cords 11.3%
- Tyre worn below the legal limit 7.8%
- Headlamp aim set too low 7.4%
2001 Vauxhall Astra 42.5% failed, from 2,419 tests
- Headlamp aim out of line 13.8%
- Exhaust leak 11.7%
- Structural corrosion 10.4%
- Sidelight out 10.4%
- Broken coil spring 9.7%
- Wiper blades that do not clear the screen 9.2%

Vauxhall Astra problems: common questions
What is the most common problem with a Vauxhall Astra?
Of the faults that fail an MOT, “Coil spring: fractured or broken” is the most common: it appears on 16.7% of failed Vauxhall Astra tests. Across categories, lamps, reflectors and electrical equipment is the area that most often fails one, on 38.1% of failed tests.
How often does a Vauxhall Astra fail its MOT?
34.2% of Vauxhall Astra tests in 2025 were not passed first time, from 584,096 tests of cars aged three and over. Allowing for the age and mileage of the cars tested, that gives it a UK Motoring Reliability Score of 47 out of 100, where 50 is as expected.
Does anything fail more often on a Vauxhall Astra than on other cars?
Yes. “Exhaust system: major leak of exhaust gases” appears on 6.0% of its failures against 3.0% for cars of the same age, and “Coil spring: fractured or broken” appears on 16.7% of its failures against 9.7% for cars of the same age. Where an item is missing from the national figures for a year, we use the smallest share those figures show, so the comparison never overstates the difference.
Are these the same as breakdowns or known faults?
No. These are the items a tester recorded at the MOT, which covers condition and safety: lamps, brakes, tyres, suspension, corrosion and emissions. A gearbox that is unpleasant, an infotainment screen that has died, or a car that will not start on a cold morning are not part of the test, so they are not in these figures.
Where do the figures come from?
Every normal MOT test of a Vauxhall Astra aged three and over in Great Britain in 2025, from DVSA's anonymised MOT results. Retests are excluded, and the same fault on more than one wheel counts once.

- Shares for defects are of failed tests; shares for advisories are of all tests. A test can carry several defects, so shares add to more than 100%.
- The expected share is what an average car of the same registration years records, weighted by where this model’s failures fall. Where an item is outside the national figures for a year, the smallest share those figures show is used in its place, which is an upper bound, so the comparison never overstates a model’s problems. No expectation is published where less than 80% of the model’s failures can be compared.
- Great Britain only: DVSA does not run MOT testing in Northern Ireland. Cars under three years old are not tested.
- The descriptions of what each part does are general and the same on every model. Every figure comes from the MOT data.
