2006 Citroen C8 — MOT failures & pass rate
1,746 MOT tests on the 2006 Citroen C8 are in this dataset, and 66.3% of them passed. Against MPVs of a similar age (29.6% fail rate), the 2006 C8 comes out 4.1pp worse. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (19.9%) and suspension (17.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are stop lamp, rbt (sp) and position lamp — stop lamp alone was recorded 160 times.
Condition tracks the odometer closely. Failures run at 27.9% in the 30-60k band and 38.4% in the 150k+ band, a 10.4-point spread.
Advisories point at the next bill rather than this one: tyres was flagged on 33.8% of tests without failing them.

What to check before buying a 2006 C8
On a 2006 C8, lighting & signalling is what the MOT record says goes wrong most — it appeared in 19.9% of tests. Check these areas before you commit.
- Lighting & signalling (19.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (17.6% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (15.7% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
