2006 BMW 7 Series — MOT failures & pass rate
Across 5,651 MOT tests, the 2006 BMW 7 Series recorded a 79.8% pass rate. Against executive cars of a similar age (23.7% fail rate), the 2006 7 Series comes out 3.5pp better. Failures cluster in suspension, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — suspension (10.0%) and lighting & signalling (9.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are position lamp, pins and bushes and rigid brake pipes — position lamp alone was recorded 300 times.
Mileage matters less than usual here: the 2006 7 Series fails 19.6% of the time in the 0-30k band and 19.3% at 150k+, a spread of only 0.2 points.
Split by fuel, diesel examples fail 3.2pp more often than petrol ones (20.8% vs 17.6%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: brakes was flagged on 30.1% of tests without failing them.
The trend is improving — the fail rate fell from 20.6% in 2021 to 18.3% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2006 7 Series
On a 2006 7 Series, suspension is what the MOT record says goes wrong most — it appeared in 10.0% of tests. Check these areas before you commit.
- Suspension (10.0% 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 (9.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (7.4% 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.
