Too bad this thread got jacked about vehicle weights.
My 2010 x5 35 d got 7.8l/100km on a 300 km road trip, mostly highway/high speed and it gets around 10 in the city.

Wow thats great economy. Are you running Run flat tyres or normal tires. Did you reset the economy meter on the hwy or while filling up.

Thx

Kumho Eissens, not run flats.
Reset as soon as on highway.

Hello all and would like to post update.2 weeks ago i felt the smell of exhaust fumes in the cabin while first starting it during cold morning.I checked it under the bonnet and was coming from the rear right hand side of the engine.First i was thinking of common egr problem.Took it to the dealer and they found that throttle valve was leaking and they changed it.After that no more fumes and economy went to 8.5l/100km (27.6MPG) from 11.2l/100km with 50-50 hwy city driving.I am not fully sure because now the weather has warmed up too (around 10-12 degrees centigrade and before was around -5 degrees).But it was same fill up.So same diesel but warmer weather.Not sure if its the throttle valve or warmer weather that fixed it.

I also have a 2009 X5 35d, and was wondering if my problem might stem from the throttle valve as well. The throttle valve is that the same thing as the EGR valve?
I was just thinking of pulling that appart and cleaning its carbon build-up. What did the dealer bill say for the kind of work performed?

It was under CPO warranty.Both engine mounts were shot too.The SA was saying that this throttle valve and engine mounts + labor would have cost me around 2000$.They charge 170$ /hour.I was having vibrations that i could feel from the floor,steering wheel but now much better.

Just got 24.17 mpg after 510.2 miles

I live in a pretty hilly area so I'm very pleased with the results so far.
