Hi Lotimo


My 04 XS averages 24 ~ 27 mpg and gts up around 30mpg on a long run.



This cold weather running with all the toys switched on heated seats ect will pull it down to around 20 ~ 23. Intresingly when its towing my caravan the fuel economy doesn't change.



Mine is an auto I would expect the manuals to be better.

hi folks, I have a 56 plate facelift version xs diesel auto and i get late 20s about town and early 30s on long run. I disagree about milage not changing when towing. I normally neraly touch 480 to 500 a tank but when i towed my van it drops to aroung 350 a tank. It is a big van though

When towing I do tend to lock it in gear rather than let the auto hunt up and down the gearbox, this helps a lot with fuel economy especially on motorways. Maybe thats why I dont see a huge diffrence in mpgwhen towing -
BTW I tow a Coachman Pastichewhich is about 24ft long and weighs approx1450kg.

My 2006 xt auto is returning very low mpg in general towing a 1200k van it returned 16.3 getting around 25 local running tops with original filter 21 with K&N before cleaning.The car has a power box fitted and a K&n filter which I have just cleaned and very lightly oiled.Tried running with the original filter when waiting for drying etc, got a much better return. I am begining to wonder if the Maf filter is oiled up as I havn,t had the car very long. Would welcome any help including how to clean the MAF. The car has only done 35000miles and I am veryMPG aware when driving.
Regards JohnLad

I think half the trouble is People mess with their engines. K & N filters / Power boxes etc.


I think the various manufactures have invested plenty of time in research and development in what is best for their engines and that by changing those settings you run the risk of making things worse.


The only thing I would advise is a full service and tuned to perfection by a specialist diesel shop.

There is plenty scope in a standard diesel engine to extract more power without affecting longevity and consumption.

My van is a Lunar Clubman 475CK this is the first time I have towed it with the sorento (also old model)Only did a 80mile long trip though filling up prior to leaving and on return. I would be quite happy with your MPG results though as I got quite a shock after checking. Thanks for the reply.

If you have a filter which is oily it is possible that the air flow and temperature sensor is contaminated.Remove plug connector and sensor is held with twotamper-proof screws.These can be got out byusinga small screwdriver filed or groundwidth-wiseto wedge in screw head one side ofcentretit.Clamp Mole grips on screwdriver to turn to unscrew.Pull out unit and spray with fast drying electrical cleaner aerosol spray.In thecentreis the air flow sensor and you will see the small air temperature resistor one side,give them a really good blast,and when dry replace.I would advise to resort to original filter.My Sorento has done 2000 miles less than yours and i replace air filter every yearregardlessof mileage done.I have been caravanning 40 years and Sorento is the best i have had, far superior to the Discovery i bought new previously.

Thanks very much for the info which confirms my suspicions and i will clean the area asap as you advise.
Would you mind confirmingas I am not quite sure the part to be cleaned is attatched to the filter box as I don't want to be messing with the wrong part.

Best regards John

Yes you are correct just take outlet hose off and unplug sensor connector then you can work on it easy.The temperature resistor can be checked by putting a multi-meter set on OHMS scale on each side of it and breath hot air on it and resistance should alter.
