The picture
Across 464 MOT tests, the Master Lm35 Business + Dci returns 75.9% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is windscreen damage. A number-plate lamp out and wipers that don't clear the screen round out the top three. Average tested mileage sits at 62,300, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis
First-time MOT pass rate split by registration band. A 1.4-point gap between bands is modest — the year you buy Renault Master Lm35 Business Dci makes a small but real difference to MOT outcomes.
Best band to buy
78.3%
2021+ registration
the 2021-on band climbs to 78.3% — a 1.4-point improvement. Tests in this band average 62,384 miles — roughly 12K miles fewer on the clock than the older band. Failures here are mostly wear items: damaged but not adversely affecting driver's view, inoperative in the case of multiple lamps… — the structural issues that drag down older examples don't appear in the top-10 for this band. Post-2020 examples are early in their MOT life and generally show the cleanest records.
Band to be cautious about
76.9%
2018–2020 registration
On the 2018–2020 band, the data shows a 76.9% pass rate against a fleet average of 78.3% on the newer band. The main culprits logged at test: damaged but not adversely affecting driver's view, inoperative in the case of multiple lamps…, and not working. Average mileage on test for this band is 74,410 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (78.3% first-time pass). Worst band to avoid: 2018-2020 (76.9% pass). That's a 1.4-point spread across 860 older tests and 901 newer ones — year of build makes a material difference on this model.
