About the 2004 Auto-Trail Motorhome
The 2004 Auto-Trail Motorhome is a motorhome. Our records list a 2800cc diesel engine, though engines vary between versions. 80 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. Among all models from 2004, the average MOT pass rate is 72%, and this model beats that benchmark.
With an average of 51,443 miles recorded at its 2024 MOT tests, Auto-Trail Motorhome 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 Auto-Trail Motorhome 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 Auto-Trail Motorhome?
Total estimated annual running cost is £2,641 (£220/month), broken down as £1,676 fuel, £410 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 75% pass rate. Keeping on top of servicing will help avoid surprises.
Buying a Used 2004 Auto-Trail Motorhome
At 22 years old, the Auto-Trail Motorhome 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 80 tests in our data, these figures should be treated as indicative rather than definitive.
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 outShort journeys clog the DPF. Replacement costs £1,000-£2,500. Check the DPF warning light and ask about driving patterns.
Turbo Wear
Watch outDiesel turbos work harder and wear faster. Listen for whining noises and check for oil leaks around the turbo housing.
EGR Valve
Watch outExhaust Gas Recirculation valves clog with carbon deposits, causing rough running and poor economy. Cleaning costs £150-£300, replacement £300-£600.
Dual Mass Flywheel
Watch outLarger 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 outAt 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 outRubber 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 riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
