Citroen Relay 35 L3h2 Eprise Bhdi S/s MOT Failures
An analysis of 48,483 real DVSA MOT tests on the Citroen Relay 35 L3h2 Eprise Bhdi S/s — what fails, how often, and how that compares to every other car on UK roads.
Where the Citroen Relay 35 L3h2 Eprise Bhdi S/s fails its MOT
The single biggest MOT failure point on the Citroen Relay 35 L3h2 Eprise Bhdi S/s is light unit fault — this model is 41 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 48,483 MOT tests, 1% of all Citroen Relay 35 L3h2 Eprise Bhdi S/s tests recorded this as a failure.
Lighting faults are usually straightforward to fix (bulbs, connectors, earth points) but can indicate deeper wiring issues on older cars. Check all lights including fog lamps, number plate lights, and dashboard warning lights.
Other notable weak points include parking brake efficiency less than 50% of the r... (19x the fleet average), obligatory mirror or device slightly damaged or... (14x the fleet average), emissions failure (16x the fleet average), and sharp bodywork damage (29x the fleet average). These ratios compare the Citroen Relay 35 L3h2 Eprise Bhdi S/s's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 6 categories: Lights & Electrics, Brakes, Wipers & Windscreen, Exhaust & Emissions, Bodywork and others. If you're inspecting a Citroen Relay 35 L3h2 Eprise Bhdi S/s before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Citroen Relay 35 L3h2 Eprise Bhdi S/s's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Citroen Relay 35 L3h2 Eprise Bhdi S/s specifically, the DVSA data shows the most common failures at this mileage are power steering fault (167x the average) and light unit fault (41x). sharp bodywork damage (29x) and headlight fault (19x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Citroen Relay 35 L3h2 Eprise Bhdi S/s specifically, the DVSA data shows the most common failures at this mileage are sharp bodywork damage (17x the average) and brake hoses perished or damaged (16x). light unit fault (15x) and parking brake efficiency less than 50% of the r... (9.5x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Citroen Relay 35 L3h2 Eprise Bhdi S/s specifically, the DVSA data shows the most common failures at this mileage are light unit fault (22x the average) and parking brake efficiency less than 50% of the r... (7.7x).
The shift from power steering fault at lower mileages to light unit fault at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
What to check before buying a Citroen Relay 35 L3h2 Eprise Bhdi S/s
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Citroen Relay 35 L3h2 Eprise Bhdi S/s:
Lights & Electrics — check for light unit fault, headlight fault. Brakes — check for parking brake efficiency less than 50% of the r..., parking brake efficiency below minimum requirement. Wipers & Windscreen — check for obligatory mirror or device slightly damaged or.... Exhaust & Emissions — check for emissions failure.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. Enter any reg into our free car check to see the complete picture.
