BMW 535i — MOT pass rate & failures
The BMW 535i passed 84.4% of its 6,882 MOT tests, covering model years 1980–2025. That tracks the BMW 5 Series range as a whole almost exactly. Failures concentrate in lighting & signalling, suspension and tyres.
What the MOT record shows
At component level the recurring items are headlamp aim, washers and catalyst emissions — headlamp aim alone was recorded 261 times.
Mileage is the strongest signal on the record: 10.0% of 0-30k cars fail, rising to 20.4% once past 150k — 2.1× the risk.
Advisories point at the next bill rather than this one: brakes was flagged on 18.8% of tests without failing them.
The trend is improving — the fail rate fell from 17.8% in 2021 to 13.7% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a BMW 535i
Focus on the areas it most often fails on — and remember MOT data covers testable defects only, not engine or gearbox health.
- Lighting & signalling (6.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (5.6% 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.
- Tyres (4.5% 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.
