About the 2021 PEUGEOT HORIZON
The 2021 PEUGEOT HORIZON is a small family car with a 1498cc diesel engine. 555 of these vehicles were MOT tested in 2026, making it a less common model in the UK market. It sits in the bottom 80% of 2021 cars for MOT pass rates.
With an average of 15,392 miles at 5 years old, PEUGEOT HORIZON 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.
2021 PEUGEOT HORIZON Fuel Costs
The 1498cc diesel engine offers a reasonable balance between performance and economy. Expect around 55 mpg in mixed driving, which works out to roughly £905 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 2021 PEUGEOT HORIZON?
Total estimated annual running cost is £1,505 (£125/month), broken down as £905 fuel, £195 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 89% pass rate. Keeping on top of servicing will help avoid surprises.

Common Issues to Watch For
Based on the 2021 PEUGEOT HORIZON's fuel type, age, and engine size, these are the most likely problem areas to check.
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
Medium riskDiesel turbos work harder and wear faster. Listen for whining noises and check for oil leaks around the turbo housing.
AdBlue System
Medium riskPost-2015 diesels use AdBlue for emissions. Sensor failures and tank heater issues are common. Budget £200-£500 for repairs.
EGR Valve
Low riskExhaust Gas Recirculation valves clog with carbon deposits, causing rough running and poor economy. Cleaning costs £150-£300, replacement £300-£600.
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.
