2010 Renault Trucks Master 100 35 Lwb — MOT failures & pass rate
The 2010 Renault Trucks Master 100 35 Lwb passed 76.8% of its 276 recorded MOT tests. Against all cars of a similar age (24.4% fail rate), the 2010 Master 100 35 Lwb comes out 1.2pp better. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 15.9% of tests against 10.9% for the next-worst category.
At component level the recurring items are rbt (sp), joints and stop lamp — rbt (sp) alone was recorded 14 times.
Condition tracks the odometer closely. Failures run at 30.0% in the 60-90k band and 15.5% in the 150k+ band, a 14.5-point spread.
Suspension is the most common advisory, noted on 22.8% of tests — work that passed today but is likely due soon.
The trend is worsening — 14.3% of tests failed in 2021 against 24.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2010 Master 100 35 Lwb
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 15.9% of tests. Start there.
- Lighting & signalling (15.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (10.9% 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.
- Suspension (8.3% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
