Poor fuel consumption on a new Kia Rio diesel

Hi,
I have a new Kia Rio 1.5 diesel. It has done 2,000 miles and yet I am only getting an mpg of less than 50mpg. I live in quite a rural area but predominently A roads and have been driving sensibly, and not in a city/town.
The quoted Urban (cold) mpg is 52.3, and the combined 62.8.
Is it worth a call to the garage or is this just the norm. I know I can't expect to get the quoted figures but expected to get somewhere near the combined figure, not less than the Urban one!

Are your tyres at the correct pressure?0

yeah I have checked tyre pressure and it is ok.0

The only other thin I can think of is binding brakes although I would be surprised if this happened on a new car.
It could be that you need to wait for the car to run in a bit and loosen up - its possible you might see the MPG improve with more miles. It could be worth asking the dealer about it anyway.0 -
yeah I will maybe go along and see what they say about it just don't want them to look at it and then charge me anything!
I was unsure whether the running in argument was a myth or not.0 -
It could possibly be because the engine is still tight at 2000 miles.;)0

In my experience from owning several diesels over the years you won't really notice anywhere near the quoted figures until 10,000 miles - I would also take the official figures with a pinch of salt. Again from my experience I would knock around 10% of those.0

I agree with the last two comments. Get some more miles under your belt.
How are yoy calculating mpg? On board computter or pencil and paper after a fill up?
If not the later fill car drive till you need to fill up and do your calculations then.
With my heavy foot if I get within 20% of quoted figures I would be over the moon...;)0 -
Thanks for replies.
You seem to have cleared up that 'new car requiring run in' is not a myth, which I thought with modern technology was no longer required.
pen and paper method for calculating mpg as it has no computer0 -
Remember the quoted figures are gained under test conditions, not in real world driving.0
) you shouldn't be charged anything full stop!
