    My 07 3.0 TDi's been remapped already.

    Looked in the boot and according to the label it DOES have a DPF, no problems whatsoever so far.

    So questions are:

    1) Will I need to get it remapped again once DPF is removed
    2) What are the disadvantages?
    3) Advantages?
    4) Has anyone had it done & what did you pay?

    And finally I do appreciate the saying... 'if it ain't broke...:unsure:

    1. Yes you will
    2. Possibility of a little smoke now and then, how much depends on the map.
    3. Increased Reliability, Power, Economy.
    4. Prices vary depending on competency of the company. We are in Manchester and a specialist and charge £500 drive in drive out for everything, guaranteed with after sales care.

    Thanks, Rick

    Thanks Rick

    1) I'll probably not bother knowing that
    2) Good to know
    3) Is an Alientech eco remap that currently has seen me do 55MPG+ and 950 miles on a tank
    4) Anything from anyone else?

    Dunno, read a post where NO DPF is designated by a certain code on a sticker inside the boot, mine doesn't hve that designation so am assuming so.:confused:

    Mine is an 07 as well, with code 7GN (DPF preparation) on the spare wheel well sticker, and it does not have a DPF fitted... its just a little secondary cat near the passenger foot well (which I am contemplating having cut out).

    For what its worth, I don't get any smoke (with a "power oriented" remap) unless I absolutely stomp on it. I would bet that with a "economy" map, there would be 3/5ths of sod-all smoke even at load, as the fuelling would be dialled way back.

    Mine DOESN'T have 7GN on the boot sticker, which means it has a DPF.

    Not that I've noticed, maybe a little hunting on the revs just below 2k

    As to the grunt both of my previous cars were a little quicker (LPG'd dual remapped XK8 and supercharged MX5 18psi).

    On the run that returned the 55MPG I was stopped by Mr Plod for doing XXX MPH that rsulted in my first 6 points in 30yrs of driving :ohmy:

    So fitted a performance exhaust so I can 'hear my speed' better...but the cars so darned well insulated only those outside can appreciate it :huh:

    Am wondering if DPF removal/Auto-RX/Terraclean can see me hit close to 60MPG :salute:

    I would wager you will see a healthy increase in MPG if you do get it removed, as they really do bung up the airflow.

    Yep most probs the same as a Cat on a petrol car, removed them from my XK8 (not needed as LPG) and saw a 4MPG increase straight away...more power too :)
