About the 2005 Citroen Relay

The 2005 Citroen Relay is a van. Our records list a 1997cc diesel engine, though engines vary between versions. 808 MOT tests were recorded on this model in 2024, making it a less common model in the UK market. It sits in the bottom 5% of 2005 models for MOT pass rate.

With an average of 106,101 miles recorded at its 2024 MOT tests, Citroen Relay owners tend to use this car less than the typical driver.

2005 Citroen Relay Fuel Costs

The 1997cc diesel engine offers a reasonable balance between performance and economy. Expect around 48 mpg in mixed driving, which works out to roughly £1,397 per year with diesel at 199.33p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year). Diesel cars of this age should have their DPF (diesel particulate filter) checked, as replacements can be costly.

What does it cost to own a 2005 Citroen Relay?

Total estimated annual running cost is £2,427 (£202/month), broken down as £1,397 fuel, £275 road tax, £55 MOT, and £700 predicted repairs. The higher repair estimate reflects the 63% MOT pass rate. Cars in this bracket tend to need work on suspension, brakes, and emissions components.

Citroen Relay Reliability Trend

Newer Citroen Relays pass their MOT more often than older ones, by 11 percentage points on average, which is mostly down to age and wear.

Buying a Used 2005 Citroen Relay

At 21 years old, the Citroen Relay is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age.

Common Issues to Watch For

These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.

DPF (Diesel Particulate Filter)

Watch out

Short journeys clog the DPF. Replacement costs £1,000-£2,500. Check the DPF warning light and ask about driving patterns.

Turbo Wear

Watch out

Diesel turbos work harder and wear faster. Listen for whining noises and check for oil leaks around the turbo housing.

EGR Valve

Watch out

Exhaust Gas Recirculation valves clog with carbon deposits, causing rough running and poor economy. Cleaning costs £150-£300, replacement £300-£600.

Rust and Corrosion

Watch out

At 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.

Suspension Bushings

Watch out

Rubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.

Clutch Wear

Watch out

With an average of 106k miles, clutch replacement may be due (typical lifespan 60,000-100,000 miles). Budget £400-£800 for a new clutch kit.

Brake Discs and Pads

Medium risk

High-mileage cars often need brake disc replacement, not just pads. A full set of discs and pads costs £200-£500 per axle.

Higher Than Average Failure Rate

Watch out

With a 63% MOT pass rate, this model fails more often than most. Budget for unexpected repairs and get a thorough pre-purchase inspection.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
