About the 2020 Fiat Hymer

The 2020 Fiat Hymer is a motorhome. Our records list a 2300cc diesel engine, though engines vary between versions. 140 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. Among all models from 2020, the average MOT pass rate is 92%, and this model falls short of that benchmark.

With an average of 15,151 miles recorded at its 2024 MOT tests, Fiat Hymer owners tend to use this car less than the typical driver.

2020 Fiat Hymer Fuel Costs

The 2300cc diesel engine offers a reasonable balance between performance and economy. 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.

Total estimated annual running cost is £2,131 (£178/month), broken down as £1,676 fuel, £200 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 91% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.

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 2020 Fiat Hymer

At 6 years old, the Fiat Hymer offers good value with plenty of life remaining. Most manufacturer warranties will have expired, so a pre-purchase inspection is worth the cost. 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

Medium risk

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

AdBlue System

Medium risk

Post-2015 diesels use AdBlue for emissions. Sensor failures and tank heater issues are common. Budget £200-£500 for repairs.

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

Medium risk

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

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.
