2001 Peugeot 106 — MOT failures & pass rate
The 2001 Peugeot 106 passed 70.4% of its 7,818 recorded MOT tests. City cars of a similar age fail at 28.7%, so the 2001 106 sits squarely on the average. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
Lighting & signalling dominates the failure mix at 17.0% of all tests — 5.5 points clear of brakes, so it is the first thing to check.
At component level the recurring items are catalyst emissions, service brake performance and stop lamp — catalyst emissions alone was recorded 819 times.
Condition tracks the odometer closely. Failures run at 19.0% in the 0-30k band and 35.7% in the 150k+ band, a 16.7-point spread.
Split by fuel, petrol examples fail 3.6pp more often than diesel ones (29.8% vs 26.2%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: tyres was flagged on 25.9% of tests without failing them.
The trend is improving — the fail rate fell from 29.8% in 2021 to 28.1% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2001 106
On a 2001 106, lighting & signalling is what the MOT record says goes wrong most — it appeared in 17.0% of tests. Check these areas before you commit.
- Lighting & signalling (17.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (11.5% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Body, structure & corrosion (11.2% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
