The picture
Across 5,543 MOT tests, the Expert Professional L1 Bluehdi returns 78.8% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is wipers that don't clear the screen. Brake pads worn below 1.5 mm and windscreen damage round out the top three. Average tested mileage sits at 53,401, 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. Pass rates barely move across bands here, so the year you buy Peugeot Expert Professional L1 Bluehdi makes little measurable difference to MOT outcomes.
Best band to buy
79.8%
2021+ registration
the 2021-on band climbs to 79.8% — a 0.8-point improvement. Tests in this band average 52,542 miles — roughly 13K miles fewer on the clock than the older band. Failures here are mostly wear items: constant velocity boot severely deteriorated, less than 1.5 mm thick — 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
79.0%
2018–2020 registration
On the 2018–2020 band, the data shows a 79.0% pass rate against a fleet average of 79.8% on the newer band. The main culprits logged at test: inoperative in the case of multiple lamps…, damaged but not adversely affecting driver's view, and does not clear the windscreen effectively. Average mileage on test for this band is 65,976 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (79.8% first-time pass). Worst band to avoid: 2018-2020 (79.0% pass). That's a 0.8-point spread across 8,558 older tests and 4,490 newer ones — year of build makes a material difference on this model.
