Hello People

My missus focus 52 plate 1.8tddi seems to be using alot of diesel its running roughly 40mpg, i cleaned the EGR valve out 2 weeks ago (i couldnt believe the amount of crap that was in it)

Does any 1 know what this could possibly be? :blink:

Also just out of interest does any 1 know what the best software is to use with an ELM327, i cant seem to get any to talk to the ecu.

I'd recommend regularly using Miller's Diesel Power Sport 4

Things to check:

1. Wheel/tyre size: My MPG dropped through the floor when I had 215/40/17s on.
2. Tyre pressures should be 32PSI all round.
3. Change air filter
4. Change fuel filter

Just some stuff off the top of my head. No one thing I've mentioned would cause MPG to drop to 40. Mine was down to about 43 when I had big daft tyres on - two of which were losing about 12lb every couple of weeks. Back on 15s now, 139k on the clock and get about 55MPG.

Also, lugging extra weight around with you all the time will cost a couple of MPG, so take trolley jacks/tool boxes, gallon bottles of screenwash etc out the boot.

Thats brilliant, thank you for your reply, i've just ordered some millers, it has actually got 17's on it, which i'm looking to take off very soon (will be up for sale ;) )

It hasnt long had a service, but i do need to get a fuel filter.

I have read some where that you can get an egr bypass for these, do you know where i could get 1 or any sort of instruction so i coule do it myself, i think its still a bit blocked up which isnt going to help.

Thanks

Shane
