About the 2004 Fiat Hymer

The 2004 Fiat Hymer is a motorhome. Our records list a 2800cc diesel engine, though engines vary between versions. 132 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. It ranks in the top 14% of all 2004 models for MOT pass rate.

With an average of 66,922 miles recorded at its 2024 MOT tests, Fiat Hymer 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.

2004 Fiat Hymer Fuel Costs

The 2800cc 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 £1,676 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 2004 Fiat Hymer?

Total estimated annual running cost is £2,491 (£208/month), broken down as £1,676 fuel, £410 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 86% pass rate. Keeping on top of servicing will help avoid surprises.

Fiat Hymer Reliability Trend

Newer Fiat Hymers pass their MOT more often than older ones, by 23 percentage points on average, which is mostly down to age and wear.

Buying a Used 2004 Fiat Hymer

At 22 years old, the Fiat Hymer 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. If you're flexible on year, the 2017 model has the highest pass rate at 95%.

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.

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.

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.
