About the 1991 CITROEN C25

The 1991 CITROEN C25 is a large car with a 2500cc diesel engine. 86 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It sits in the bottom 92% of 1991 cars for MOT pass rates.

With an average of 89,172 miles at 35 years old, CITROEN C25 owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.

1991 CITROEN C25 Fuel Costs

The 2500cc diesel engine is on the larger side, so fuel won't be this car's strong point. Expect around 40 mpg in mixed driving, which works out to roughly £1,245 per year at current diesel prices of 148p per litre (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 1991 CITROEN C25?

Total estimated annual running cost is £2,395 (£200/month), broken down as £1245 fuel, £395 road tax, £55 MOT, and £700 predicted repairs. The higher repair estimate reflects the 64% MOT pass rate. Cars in this bracket tend to need work on suspension, brakes, and emissions components.

CITROEN C25 Reliability Trend

Older CITROEN C25s tend to have better MOT pass rates than newer ones, with an average decline of 6 percentage points across model years.

Buying a Used 1991 CITROEN C25

At 35 years old, the CITROEN C25 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. Note: with only 86 tests in our data, these figures should be treated as indicative rather than definitive.

Common Issues to Watch For

Based on the 1991 CITROEN C25's fuel type, age, and engine size, these are the most likely problem areas to check.

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.

Dual Mass Flywheel

Watch out

Larger diesel engines put extra strain on the dual mass flywheel. Listen for rattling at idle. Replacement with clutch is £800-£1,500.

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

Medium risk

With an average of 89k 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 64% 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.
