If it's mostly short journeys this won't help dpf, they need good regular blasts on mway to stop it from clogging.

If you find an answer I would be interested because you are matching my consumption. Got 43.4 last time with town and 2 trips Newark to Bolton, Bolton Newark on motorways at 70mph when possible

If your 42mph was entirely motorway It must have been the m25. I would expect more than 42mpg from all-inclusive motorway work.

Before going down the diagnostic route, lets start with the basics...
- when did you last check tyre pressures?
- have you got a roof rack on?
- do you carry weight around in the boot?
- when was the last service? filters inparticular?

See to all the basic things first before going straight down the "diagnostics its got a fault" approach.

Don't forget, at this time of year, and particularly now as its pretty cold, your consumption will increase :nod: something to do with diesel being more dense... go to the arctic, and it might solidify :eek:

:)I have the 2.0 hdi and i have been keeping a eye on my fuel mpg. My trip to work early morning with no traffic on roads is 4 miles if i go on the bypass and i average 37mpg. If i cut through newark town still no traffic at the time i go, its only 2 mile trip to work but my mpg is 28mpg, this is all normal driving and being gentle with the throttle.
Last week i did a 40 mile trip down the A46, i was keeping it around the 50-60 mark and the car returned 54mpg. Yesterday i went down the A1 to Grantham and back doing 80 mph on the A1 and the car returned 40 mpg. I have just serviced my car and no faults are showing.

See after you do a journey today , get out and using the back of your hand check the brake discs for excessive heat .
:)After a short trip back from work around 4 mile, i touched the discs seeing i had not used the brakes much. The front were warm and the rear were a lot warmer, so perhaps the brakes might be sticking slightly. My rear pads need changing to be honest, so might be good idea to give them a good clean.:)

Well a small improvement today, small bit of town work in Boston, then a17 to newark and cross pennine m62 to atherton. again 5 miles tops in town, back to lincoln dual/motorways and back to ferrybridge A1, I got 45.7. I will check my brakes next time out for heat and see what happens.

I have a 1.6hdi 407. Bought the car for it's frugal fuel usage.

I do 10 mins town/A roads, then 30mins Motorway, followed by 20mins A roads/town. 40 miles in total (each way to and from work, 80 mile round trip, Maidstone to Croydon)

I get 49/50mpg on the display, an actual of 45/46mpg, when you work out the mileage vs litres used. That's travelling at +5 over the speed limits, and 75-80 on the motorway. I get 600miles to a tank basically.

I have gone on an eco warrior war, seeing as diesel has gone up so much! Well I tried for a full tank of fuel. Driving between 60-65 mph on the motroway, I got a display of 54-56mpg, an actual of 50mpg-ish.

Trust me driving at 60-65mph on the motorway may have given me 60 more miles to a tank, but I was either going to go round the twist, or be killed by lorries that aren't restricted to 60mph!!

A lot of fuel economy I guess come from how urgent your drive from A to B is.

Well that's what I found any way.
