I think the introduction of the Dpf hurt fuel consumption in the quest for reduced emissions.?

 

Regens use a good amount of fuel so i  would expect the Town driving would be a bigger hit on overall consumption than it used to be.?

Not just town driving though. Whenever a regen starts your car is throwing fuel straight

into the exhaust and bypassing the engine.

 

I dont think the DPF is all its cracked up to be, just creating finer soot which gets burnt

in a shorter period rather than a more efficient engine creating less soot to start with.

I agree

 

Surely it is probable that the Dpf actually hides some engine problems (initially) because you won't realise you have a sooty problem until you notice excessive regenerations and reduced mpg

Thanks all for the responses and the tips and tricks. I am driving like Miss Daisy, 70-75Mph on motorway and looking ahead when in town to keep the vehicle moving. I can just about get 40.9MPG doing this all the time. The car has 206,300 miles on, would that be a reason? I've replaced the injectors and turbo. 

 

I still can't understand why the fuel economy is just so low, especially compared to the Parkers.com review of the car indicating over 51MPG and 900 Miles per tank!?!

My water temp / engine temp never gets any higher than this, could this be something to do with my appalling fuel economy? Could my thermostat be on the blink?

Do you think it could be DPF related, the car has done 206,300 miles. Would a delete be an option with a remap?

I think temperature related, its running cool and probably adding more fuel

to help warm it up but its not getting as hot as it should.

 

Another thread had a similar issue and it helped more than i expected.
