About This Data
The 1991 Citroen C25 Relay has an MOT pass rate of 43.7% based on 403 tests — significantly below the UK average for UK vehicles.

If you own or are considering buying a 1991 Citroen C25 Relay, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to lamps, reflectors and electrical equipment: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test. With an average mileage of 99,523 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Lamps, Reflectors and Electrical Equipment — 3.2% of failures
Lamps, Reflectors and Electrical Equipment issues account for 3.2% of MOT failures on 1991 Citroen C25 Relay models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
Suspension — 1.7% of failures
Suspension issues account for 1.7% of MOT failures on 1991 Citroen C25 Relay models. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Exhaust, Fuel and Emissions — 1.2% of failures
Exhaust, Fuel and Emissions issues account for 1.2% of MOT failures on 1991 Citroen C25 Relay models. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.
