Renault Trafic Ll30 B-Ness+ MOT pass rate & common failures
Across 4 model years and 1,095 tests, the Renault Trafic Ll30 B-Ness+ passes its MOT 84.0% of the time. Against all cars of a similar age (8.9% fail rate), the Trafic Ll30 B-Ness+ comes out 7.0pp worse. Its most common failure areas are suspension, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — suspension (6.7%) and lighting & signalling (5.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are brake pads, shock absorbers and track rod end — brake pads alone was recorded 54 times.
Condition tracks the odometer closely. Failures run at 14.2% in the 0-30k band and 21.5% in the 90-120k band, a 7.3-point spread.
Advisories point at the next bill rather than this one: brakes was flagged on 19.0% of tests without failing them.
The trend is improving — the fail rate fell from 16.7% in 2023 to 14.8% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a Renault Trafic Ll30 B-Ness+
- Suspension (6.7% 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 (5.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (5.0% 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.
