675 MOT tests on the Renault Master Lm35 Start Blue (2023–2025) give it a 90.4% pass rate. Against all cars of a similar age (5.6% fail rate), the Master Lm35 Start Blue comes out 4.0pp worse. Its most common failure areas are lighting & signalling, tyres and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (6.8%) and tyres (4.3%) are close, so failures are spread across several systems rather than one weak point.

Advisories point at the next bill rather than this one: tyres was flagged on 15.4% of tests without failing them.

What to check before buying a Renault Master Lm35 Start Blue
- Lighting & signalling (6.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (4.3% 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.
- Visibility (2.5% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
