Citroen Relay MOT Reliability Overview

The Citroen Relay is one of the most widely tested vehicles in the UK, with 643,588 MOT test results recorded in our database spanning 31 manufacture years. It has an overall MOT pass rate of 55.5% and a failure rate of 44.5%, which is slightly below the UK average of approximately 37%.

Based on this data, the Citroen Relay earns a "Below Average" reliability rating. The average Citroen Relay presents for MOT with approximately 94,216 miles on the clock. Manufacture year matters: 2021 models achieve the highest pass rate at 74.1%, while 1998 models have the lowest at 39.9%. This 34.2 percentage point difference suggests notable variation in build quality or component durability across production years.

The most common MOT failure for the Citroen Relay is Brakes, affecting 45.8% of all tests. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. The second most common issue is Suspension at 42.5%. Lamps, Reflectors and Electrical Equipment rounds out the top three at 26.8%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

💡 What does the warranty cliff mean?

The Citroen Relay ages relatively gracefully. The failure rate increase of 18% after warranty is below average, suggesting good long-term reliability. Peak failure occurs at age 13 (53.3% fail rate).

Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

* High Fail Rate badge indicates an MOT pass rate below 65% (failure rate above 35%).

About Citroen Relay MOT Data

The Citroen Relay is one of the most widely tested vehicles in the UK, with 643,588 MOT test results recorded in our database spanning 31 manufacture years. It has an overall MOT pass rate of 55.5% and a failure rate of 44.5%, which is slightly below the UK average of approximately 37%.

For Citroen Relay owners, these results suggest average reliability — some preparation before MOT can improve pass chances. Focus your pre-MOT checks on brakes and suspension for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Relay is likely to perform.

Brakes — 45.8% of failures

Brakes issues account for 45.8% of MOT failures on the Citroen Relay. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).

Suspension — 42.5% of failures

Suspension issues account for 42.5% of MOT failures on the Citroen Relay. 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.

Lamps, Reflectors and Electrical Equipment — 26.8% of failures

Lamps, Reflectors and Electrical Equipment issues account for 26.8% of MOT failures on the Citroen Relay. 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.
