1999 Peugeot 106 — MOT failures & pass rate
The 1999 Peugeot 106 passed 68.8% of its 1,822 recorded MOT tests. City cars of a similar age fail 27.4% of the time, so this is 3.8pp worse than the group it competes with. Failures cluster in emissions & environmental, brakes and lighting & signalling.
What the MOT record shows
No single area dominates — emissions & environmental (16.5%) and brakes (13.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, component mounting prescribed areas and service brake performance — catalyst emissions alone was recorded 433 times.
A 150k+ example is materially riskier than a 0-30k one: 32.6% versus 22.5%.
Suspension is the most common advisory, noted on 22.7% of tests — work that passed today but is likely due soon.

What to check before buying a 1999 106
The failure pattern for this year is specific enough to inspect against: emissions & environmental accounted for 16.5% of tests. Start there.
- Emissions & environmental (16.5% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Brakes (13.8% 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.
- Lighting & signalling (12.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
