2006 Jaguar Xjr — MOT failures & pass rate
752 MOT tests on the 2006 Jaguar Xjr are in this dataset, and 80.7% of them passed. Against all cars of a similar age (27.4% fail rate), the 2006 Xjr comes out 8.1pp better. Failures cluster in suspension, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — suspension (8.2%) and lighting & signalling (6.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are ball joint dust cover, track rod end and malfunction indicator lamp — ball joint dust cover alone was recorded 87 times.
Condition tracks the odometer closely. Failures run at 13.9% in the 0-30k band and 19.4% in the 150k+ band, a 5.5-point spread.
Brakes is the most common advisory, noted on 26.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 21.4% in 2021 to 19.9% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2006 Xjr
The failure pattern for this year is specific enough to inspect against: suspension accounted for 8.2% of tests. Start there.
- Suspension (8.2% 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.
- Lighting & signalling (6.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (5.6% 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.
