2021 Renault Trafic Ll30 B-Ness+ — MOT failures & pass rate
The 2021 Renault Trafic Ll30 B-Ness+ passed 83.4% of its 694 recorded MOT tests. That is 7.9 percentage points worse than all cars of a similar age, which fail at 8.6%. Failures cluster in suspension, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — suspension (6.5%) and lighting & signalling (6.5%) 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 33 times.
Condition tracks the odometer closely. Failures run at 13.8% in the 0-30k band and 23.4% in the 90-120k band, a 9.7-point spread.
Brakes is the most common advisory, noted on 19.3% of tests — work that passed today but is likely due soon.

What to check before buying a 2021 Trafic Ll30 B-Ness+
The failure pattern for this year is specific enough to inspect against: suspension accounted for 6.5% of tests. Start there.
- Suspension (6.5% 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 (6.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (4.6% 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.
