What fails on a Citroen Relay at 8 years
All Citroen Relay MOTs at 8 years, vans first used 2014–2017 (4,990 MOT tests; DVSA item counts are not split by first-use year). The most common fail items: handbrake too weak (4.7 per 100 MOT tests), wipers not clearing screen (3.0 per 100 MOT tests, a wear item) and dipped headlight not working (2.8 per 100 MOT tests, a wear item).
Item rates are not compared with all class 4 vehicles here: most of those are cars, and vans wear differently.
Mileage and the fail rate at 8 years
Citroen Relay vans first used 2014–2017 at 90,000 to 120,000 miles failed 35.1% of MOTs at 8 years (1,022 MOT tests), against 25.2% at 30,000 to 60,000 miles (1,063 MOT tests). All class 4 vehicles: 30.2% and 21.0%.
Vehicle tax and ULEZ for a 2017 van
A vehicle first registered in the UK in 2017 was issued a 66 (January–February), 17 (March–August) or 67 (September–December) plate, unless it was registered in Northern Ireland (no age identifier) or has since moved to a private plate. An imported one is plated when first registered here, so its plate can be newer than its first-use year. 17 plates
Vans are taxed as light goods vehicles, at the light goods vehicle rate rather than by CO2 band; the tax class on the V5C logbook decides. [2]
For the London ULEZ, a diesel van needs Euro 6 (usually registered from September 2016, from September 2015 for the smallest vans) and a petrol one Euro 4 (usually from 2006 or 2007). The Euro standard decides, not the year alone. [3] ULEZ checker
