2020 Volkswagen Golf — MOT failures & pass rate
129,504 MOT tests on the 2020 Volkswagen Golf are in this dataset, and 93.0% of them passed. Against small family cars of a similar age (8.9% fail rate), the 2020 Golf comes out 1.9pp better. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
Tyres dominates the failure mix at 4.4% of all tests — 3.1 points clear of lighting & signalling, so it is the first thing to check.
At component level the recurring items are tread depth, headlamp aim and brake pads — tread depth alone was recorded 1,833 times.
A 150k+ example is materially riskier than a 0-30k one: 14.7% versus 5.2%.
Fuel type barely separates them — petrol fails 6.8% of the time against 8.1% for diesel.
Advisories point at the next bill rather than this one: tyres was flagged on 22.3% of tests without failing them.
The trend is improving — the fail rate fell from 15.0% in 2021 to 7.6% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2020 Golf
On a 2020 Golf, tyres is what the MOT record says goes wrong most — it appeared in 4.4% of tests. Check these areas before you commit.
- Tyres (4.4% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Lighting & signalling (1.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (1.1% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
