The picture
Across 1,511 MOT tests, the Expert S L1 Bluehdi returns 94.2% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is brake pads worn below 1.5 mm. A defective wiper blade and wipers that don't clear the screen round out the top three. Average tested mileage sits at 26,696, 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 S L1 Bluehdi makes little measurable difference to MOT outcomes.
Best band to buy
93.4%
2018–2020 registration
the 2018–2020 band climbs to 93.4% — a 0.1-point improvement. Failures here are mostly wear items: does not clear the windscreen effectively, blade defective — the structural issues that drag down older examples don't appear in the top-10 for this band.
Band to be cautious about
93.3%
2021+ registration
On the 2021-on band, the data shows a 93.3% pass rate against a fleet average of 93.4% on the newer band. The main culprits logged at test: less than 1.5 mm thick, insecure, and not functioning. Average mileage on test for this band is 31,060 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2018-2020 (93.4% first-time pass). Worst band to avoid: 2021+ (93.3% pass). That's a 0.1-point spread across 717 older tests and 1,692 newer ones — year of build makes a material difference on this model.
