Vauxhall Astra vs Volkswagen Golf
Take the Volkswagen Golf for lower age-adjusted MOT risk: its index is 85.1 versus 109.1 for the Vauxhall Astra, and the 95% confidence intervals do not overlap.
Lower is better. The index adjusts for each fleet's exact age profile; the raw failure rate below does not. The index gap is 24.0 points. Data release dvsa-2024-v1.
Side-by-side evidence
| Measure | Vauxhall Astra | Volkswagen Golf |
|---|---|---|
| Age-adjusted MOT Risk Index | 109.1 (108.8–109.4) | 85.1 (84.9–85.4) |
| Raw initial failure rate | 33.71% | 24.94% |
| Dangerous defects per 100 tests | 16.98 | 13.42 |
| Initial tests | 914,157 | 1,323,641 |
Where their MOT failures diverge
These are component groups present in both models' published top-six failure lists, sorted by the absolute gap. A positive difference means the Vauxhall Astra records more failure items; a negative one means the Volkswagen Golf does.
| Component group | Vauxhall Astra | Volkswagen Golf | Difference | Lower rate |
|---|---|---|---|---|
| Lamps, reflectors and electrical equipment | 29.9 | 21.3 | +8.6 pp | Volkswagen Golf |
| Brakes | 20.9 | 15.2 | +5.7 pp | Volkswagen Golf |
| Tyres | 13.0 | 11.1 | +1.9 pp | Volkswagen Golf |
| Visibility | 13.1 | 11.6 | +1.5 pp | Volkswagen Golf |
| Suspension | 24.1 | 23.3 | +0.8 pp | Volkswagen Golf |
Counts are defect items, not the share of cars: one failed test can contain several items. A group absent from a model's top six is not treated as zero.
What the six-year test history says
The longitudinal layer follows the same vehicles between MOTs from 2019 to 2024. It separates a one-day retest from the harder question of what returns next year, and puts failures against miles actually driven.
| Component | Vauxhall Astra | Volkswagen Golf | Difference | Tracked advisories |
|---|---|---|---|---|
| Body, chassis, structure | 12.5% | 21.1% | -8.6 pp | 201,169 / 124,934 |
| Suspension | 24.4% | 19.1% | +5.3 pp | 487,109 / 834,135 |
| Steering | 10.0% | 15.2% | -5.2 pp | 54,668 / 24,229 |
| Seat belts and supplementary restraint systems | 3.4% | 6.8% | -3.4 pp | 17,849 / 25,317 |
| Brakes | 15.4% | 12.2% | +3.3 pp | 855,827 / 809,662 |
| Visibility | 10.2% | 12.1% | -1.8 pp | 3,735 / 5,654 |
| Lamps, reflectors and electrical equipment | 30.3% | 31.5% | -1.3 pp | 78,690 / 55,198 |
| Tyres | 10.8% | 9.6% | +1.2 pp | 923,540 / 1,038,493 |
| Identification of the vehicle | 4.0% | 3.7% | +0.4 pp | 114,542 / 101,751 |
| Noise, emissions and leaks | 9.0% | 9.2% | -0.2 pp | 339,325 / 165,010 |
| Measure | Vauxhall Astra | Volkswagen Golf |
|---|---|---|
| Repaired and passed the same day | 46.0% | 45.0% |
| Passed 1–10 days later | 51.4% | 52.1% |
| Median retest delay | 1.0 days | 1.0 days |
| Failures per 10,000 miles | 0.545 | 0.408 |
| Three-test clean streak | 28.0% | 33.4% |
| Same advisory repeated 3+ times | 38.3% | 34.5% |
Care proxy is descriptive, not a claim about an owner's character: a clean streak means three or more consecutive tests with nothing recorded; the repeat measure means the same advisory appeared at least three times.
Safety recalls
| Model | Campaigns listed | Per 10,000 licensed |
|---|---|---|
| Vauxhall Astra | 37 | 0.70 |
| Volkswagen Golf | — | — |
More campaigns do not by themselves mean a less reliable car: recalls are manufacturer remedies, and the licensed-fleet denominator is unavailable for some families. Check a registration for outstanding work before buying.
Do other countries see the same thing?
Both models appear in the same independent national inspection datasets below. Compare each model with that country's own average; absolute pass rates are not portable between rulebooks.
| Country / test | Model | Model fails | National average | Position | Inspections |
|---|---|---|---|---|---|
| Finland · Katsastus | Vauxhall Astra | 27.8% | 26.3% | +1.5 pp | 27,136 |
| Finland · Katsastus | Volkswagen Golf | 25.5% | 26.3% | -0.8 pp | 64,483 |
| Netherlands · APK | Vauxhall Astra | 53.0% | 50.9% | +2.1 pp | 69,587 |
| Netherlands · APK | Volkswagen Golf | 49.2% | 50.9% | -1.7 pp | 175,927 |
Sources are the national PKK, Katsastus and APK datasets recorded in each family artifact. Position is model failure rate minus that country's national rate.
Quick answers
- Is the Vauxhall Astra or the Volkswagen Golf more reliable?
- The Volkswagen Golf has the stronger age-adjusted MOT result: index 85.1 against 109.1 for the Vauxhall Astra, with non-overlapping 95% confidence intervals.
- Does the Vauxhall Astra or the Volkswagen Golf fail more MOTs?
- 33.71% of Vauxhall Astra initial tests and 24.94% of Volkswagen Golf initial tests found a failing defect in 2024. The lower raw rate belongs to the Volkswagen Golf, but the age-adjusted index is the fairer model comparison because the fleets can be different ages.
- What are the main MOT problem areas on the Vauxhall Astra and Volkswagen Golf?
- The leading published failure group for the Vauxhall Astra is lamps, reflectors and electrical equipment at 29.9 items per 100 tests; for the Volkswagen Golf it is suspension at 23.3 per 100.
- Should I buy a Vauxhall Astra or a Volkswagen Golf?
- If MOT reliability is the deciding factor, the Volkswagen Golf is the evidence-led choice. Still check the individual car's MOT history and condition: these figures describe whole model populations, not a particular vehicle.

How to read and cite this comparison
Scope: class-4 vehicles, initial tests only, Great Britain 2024. PRS fixed-on-the-spot results count as failures because a defect was present on arrival. Index = observed initial failures ÷ age-profile-expected failures × 100; intervals are 95% confidence intervals. Every model family combines all generations and engines. Full method: methodology.
