However, a reasonable estimate for a 1.9D Berlingo van on a full tank (assuming a standard tank size) would be between 400 and 600 miles. This is a broad range. You might achieve more miles under ideal conditions with light loads and gentle driving, and considerably less under heavy loads, in stop-and-go city traffic, or with a poorly maintained engine.
To get a more precise idea for your specific van, check your vehicle's handbook. It will give you the fuel tank capacity and an estimated fuel consumption figure (in mpg or l/100km), which you can then use to calculate the potential range.
