reports of oil(diesel) consumption

[mercedesalbania]

Hello
My w203 with 200cdi spends 7 liter for 50 km in Urban street, and for 100 I can spends 14 litre, 14 l/100 km(urban). But in display say 8.7 l/100 km, and the report is 13 km/hour.
I put in computer and no problem can find.
Have any Idea for this, but I ask for this cause and nobody hear about this situated.
I have removed one exhaust catalyst, and clear the other, the condition were good. But no result for consumption.

Perhaps it's leaking somewhere?

My display is a little optimistic - it reads around 6 l/100km when tank to tank measurements are closer to 6.3, so I'd say that you've got fuel going somewhere other than the injectors.

thanks Colin for your replay, but I don't see any leak or any smell of diesel.
But it's inposible for this case, and my servis say that is imposibile to burn 14 l/100km.
I bought this car 3 mounth ago, I don't know how spends but was the same when i bought.
I have a problem on ignition when the motor is heat 70C and over. And is later on start.
