2007 Citroen C6 — MOT failures & pass rate
Across 808 MOT tests, the 2007 Citroen C6 recorded a 78.0% pass rate. That is 4.8 percentage points better than all cars of a similar age, which fail at 26.8%. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
No single area dominates — brakes (9.7%) and lighting & signalling (9.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are pins and bushes, service brake performance and headlamp — pins and bushes alone was recorded 43 times.
Condition tracks the odometer closely. Failures run at 12.7% in the 30-60k band and 24.1% in the 150k+ band, a 11.4-point spread.
Brakes is the most common advisory, noted on 27.2% of tests — work that passed today but is likely due soon.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a 2007 C6
The failure pattern for this year is specific enough to inspect against: brakes accounted for 9.7% of tests. Start there.
- Brakes (9.7% 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.
- Lighting & signalling (9.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (8.4% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
