The picture

Citroen Relay: challenging MOT record across 72,987 tests

The Citroen Relay is a diesel-powered van sold in the UK market across multiple generations, covering a broad date range in the test population.

MOT data from 72,987 tests puts this van on a 68.6% first-time pass rate, well below the UK fleet average. Average mileage at test is 102,450 miles. The most common fail item is cracked or discoloured windscreen, followed by parking brake efficiency below minimum requirement.

The Relay's pass rate warrants caution in the used market. Factor in likely first-test remedial work on the common failure items and get a pre-purchase inspection that covers the specific items this van trips on most.

Year-band analysis

Best year to buy. Worst to avoid.

First-time MOT pass rate split by registration band. A 6.0-point gap between bands means the year you buy Citroen Relay has a real effect on what turns up at the garage.

Best band to buy

74.5%

2021+ registration

the 2021-on band climbs to 74.5% — a 6.0-point improvement. Tests in this band average 27,016 miles — roughly 86K miles fewer on the clock than the older band. Failures here are mostly wear items: does not clear the windscreen effectively, has a serious fluid leak — 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

68.5%

Pre-2018 registration

On the older band (pre-2018), the data shows a 68.5% pass rate against a fleet average of 74.5% 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 efficiency below requirements. Average mileage on test for this band is 113,451 miles — high-mileage wear items are a recurring theme.

Best band to buy: 2021+ (74.5% first-time pass). Worst band to avoid: pre-2018 (68.5% pass). That's a 6.0-point spread across 88,234 older tests and 321 newer ones — year of build makes a material difference on this model.

Buying or keeping a Relay?

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.

If you own a Relay and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
