2005 BMW 7 Series — MOT failures & pass rate
Across 3,508 MOT tests, the 2005 BMW 7 Series recorded a 79.6% pass rate. Against executive cars of a similar age (24.1% fail rate), the 2005 7 Series comes out 3.7pp better. Failures cluster in suspension, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — suspension (11.1%) and lighting & signalling (8.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are pins and bushes, ball joint and rigid brake pipes — pins and bushes alone was recorded 167 times.
A 150k+ example is materially riskier than a 30-60k one: 21.8% versus 10.7%.
Fuel type barely separates them — petrol fails 19.7% of the time against 20.9% for diesel.
Suspension is the most common advisory, noted on 31.8% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 21.8% in 2021 to 19.5% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2005 7 Series
The failure pattern for this year is specific enough to inspect against: suspension accounted for 11.1% of tests. Start there.
- Suspension (11.1% 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 (8.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (8.3% 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.
