2022 Renault Master Lm35 Business+ Blue — MOT failures & pass rate
Across 938 MOT tests, the 2022 Renault Master Lm35 Business+ Blue recorded a 90.3% pass rate. All cars of a similar age fail 6.8% of the time, so this is 2.9pp worse than the group it competes with. Failures cluster in lighting & signalling, tyres and visibility.
What the MOT record shows
Lighting & signalling dominates the failure mix at 10.8% of all tests — 8.4 points clear of tyres, so it is the first thing to check.
At component level the recurring items are headlamp aim, outline marker lamp and wipers — headlamp aim alone was recorded 93 times.
Condition tracks the odometer closely. Failures run at 4.1% in the 0-30k band and 20.0% in the 90-120k band, a 15.9-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 15.6% of tests without failing them.
The trend is worsening — 3.5% of tests failed in 2023 against 15.4% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2022 Master Lm35 Business+ Blue
On a 2022 Master Lm35 Business+ Blue, lighting & signalling is what the MOT record says goes wrong most — it appeared in 10.8% of tests. Check these areas before you commit.
- Lighting & signalling (10.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- 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.
- Visibility (2.2% 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.
