Hi iv just bought a 16 plate dobla long wheel base 1.3 diesel van . Off 20 pounds of diesel im only doing about 125 miles . This doesnt seem rght and thats mainly motorway miles . Does this sound like a possible fault
 
My maths might be wrong because I’ve done it very quick but with current fuel prices I make that about 37mpg

It’s not great but what are you moving In the car, consider it is quite blunt nosed and doesn’t cut the air nicely like a conventional car and it also depends on your driving.

An hour in very slow moving traffic on your morning commute is going to have a terrible impact on economy versus sitting at 45mph in top gear for 20 minutes

It was mainly 60 mph on motorway . With load in back would i be better with the 1.6 version
 
I’m Not going to lie the 1.3 is a bit under powered for a van as big as the lwb doblo and tends to burn more fuel the faster you go it’s terrible at 70mph, but your figures still seem low, as I say a lot of things can make a difference such as hills, loads, driving style etc. But empty on level ground you should be getting a reasonable 50+ mpg

My Grande gp fleet do @ 60mpg on the 80 miles at 65mph M4 commute.

Not fantastic. But a LOT better than you are seeing.

As youve just bought it..we are looking to question..

Poor tyres..underinflated

Binding brakes

Engine running issues

Attempting DPF regen


What does the trip display tell you?
Should be between 30+50 on the instant display ..From what youve said

Was is being driven hard.
Or just cruising?
 
Trip display allways 20 odd to 30 odd driving just cruising nice a steady. A glow plug was faulty which theve replaced . Only strange thing is there was a rev restricter on before glow plug change now since theve done that there is no restriction could this b conected to problen

The speed restrictor is common with ex.fleet vehicles

Shouldnt effect mpg though..

Obviously something odd if instant display shows so low though.

That'll be it, common problem on this engine, usually they get very blocked up with soot.

I was able to clean mine with some EGR cleaner from wynns but this was before I got any warning lights so you may have passed that point. If you have recently bought it then hopefully you have some warranty. its a pig of a job to change on the 1.3, because of its location.
 
How often do you drive at motorway speeds? The car might be trying to clean the DPF.

Try a much longer run at motorway speed and see if it improves.
