BMW x5 e53 2006 3.0d automatic GB fuel consumption

[Kokejn]

Hello Bimmers,

I have issue on my BMW x5 e53 with fuel consumption. On my board number is 15-16l/100km, i bought it recently and it is in very good condition. But i have that issue with fuel consumption. Its 3.0d 218hp with auto gearbox and is 2006.

Do you have any advice or exp with similar problem?

Hello. I have. 3.0l petrol manual version and I average 17mpg

 I recently replaced my throttle body and idle control valve and maf. Now it runs smoother and consumption has risen to 21mpg with lots more power back. 
possibly a good clean with redex and carb cleaner is a start?

Morning Kokejn

Welcome to the Forum

Consumption for the 218hp 6 speed gearbox model should be around 10ltr/100km around town and 8ltr/100km on a run 

As Stu has said first place to start is with the inlet side is everything as clean as it can be and no leaks. Parts wear and become clogged with age and Miles/Kilometers covered, Make sure the EGR is clean and working correctly as Stu said throttle bodies wear and become dirty check all Vacuum lines and and inlet hoses, final check on the inlet side are the injectors worn or clogged they have a huge effect. Is the turbo in good condition and producing correct boost 

Hope this helps
