2022 Renault Trucks Master 35 Lwb — MOT failures & pass rate
The 2022 Renault Trucks Master 35 Lwb passed 90.4% of its 533 recorded MOT tests. All cars of a similar age fail 6.6% of the time, so this is 3.0pp worse than the group it competes with. Failures cluster in lighting & signalling, brakes and tyres.
What the MOT record shows
Lighting & signalling dominates the failure mix at 11.1% of all tests — 8.4 points clear of brakes, so it is the first thing to check.
At component level the recurring items are headlamp aim, outline marker lamp and registration plate lamp(s) — headlamp aim alone was recorded 34 times.
Mileage is the strongest signal on the record: 2.5% of 0-30k cars fail, rising to 15.5% once past 90-120k — 6.2× the risk.
Advisories point at the next bill rather than this one: tyres was flagged on 10.3% of tests without failing them.
The trend is worsening — 0.0% of tests failed in 2022 against 14.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2022 Master 35 Lwb
On a 2022 Master 35 Lwb, lighting & signalling is what the MOT record says goes wrong most — it appeared in 11.1% of tests. Check these areas before you commit.
- Lighting & signalling (11.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (2.6% 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.
- Tyres (2.4% 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.
