I think you would need the dpf deleted via star as otherwise the car will be monitoring pressures in the dpf

You can't replace the DPF with a straight pipe as it will fail the MOT.
The usual method is to remove, cut open and remove the filter, and re-weld the DPF canister and re-fit.

I have read with interest all of the comments on this thread, as fuel consumption is a big thing for me, not only to avoid unnecessary waste of money wherever possible, but to try and improve the overall average mpg for my car. Observations from my experiences are below:
1) driving style is of paramount importance in this aim, avoid unnecessary braking, try to anticipate what may be required ahead of you, and act accordingly.
2 ) I have found that driving at a steady speed of around 50-55mph, on dual carriageways/motorways yields the best mpg. at first it proved very difficult to sit at this speed, almost in slow motion, but if you add a little more time for your journey it can be done
3) tyre pressures are set at the level for heavier loads, in the case of my cls 320cdi, 2.7bar front, and 2.9bar rear.
4) good maintenance schedules are essential, and as others have said already, I regularly use, Millers, Redex, and more recently - Archoil turbo cleaner, and fuel system cleaner.
5) clear out any unnecessary junk from your car, it all adds weight, and will make the engine work harder, and burn more fuel. You might be surprised at how much crap is in your boot
6) my personal choice is to reset the computer as soon as I buy a car, and then I can keep an eye on total average mpg achieved. this is stored as trip a, and you can still use trip b for single journeys. over 15500 miles of mixed driving, my car is averaging 41.6mpg, which I consider to be good. its easy to deceive yourself with figures over a single journey, but the best I have achieved is 51.8mpg, on a 300 mile journey from the north east to kent.
I have no direct experience with dpf issues, but will be interesting to see the effect on mpg after removal etc.....please update thread when appropriate

The sensor on a no dpf car is roughly where you feet ie the driver would be! Take off center plastic belly pan which is behind the one that is under the engine. Once off you will see the pipe coming down from the cat which is bigger in diameter! Where it becomes horizontal next to the front of the trans box you will see 2 items. One is the o2 sensor or lamba and this is at the top closest the bottom of the car and the largest item of the 2. Not sure what the other item (sensor) is. I know they only have one o2 sensor. Hope this is the info your after.
