2008 BMW 7 Series — MOT failures & pass rate
Across 3,995 MOT tests, the 2008 BMW 7 Series recorded an 81.7% pass rate. That is 4.2 percentage points better than executive cars of a similar age, which fail at 22.5%. Failures cluster in suspension, lighting & signalling and tyres.
What the MOT record shows
No single area dominates — suspension (9.1%) and lighting & signalling (6.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are ball joint, position lamp and pins and bushes — ball joint alone was recorded 148 times.
Condition tracks the odometer closely. Failures run at 6.5% in the 0-30k band and 17.7% in the 150k+ band, a 11.2-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 28.0% of tests without failing them.

What to check before buying a 2008 7 Series
On a 2008 7 Series, suspension is what the MOT record says goes wrong most — it appeared in 9.1% of tests. Check these areas before you commit.
- Suspension (9.1% 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 (6.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (5.1% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
