    my previous thread was closed, so just wanted to ask one question. if was to buy a 2006-2007 diesel 320d or 318d, could i simply get the DPF removed so i wont have to worry about regeneration etc or would this stop it from passing a MOT due to emissions testing?

    (my friend just got a 1.9 CDTI astra, it doesnt have DPF, so im unsure why a 320d would have a DPF tbh)

    thanks

    If the tail pipe is pointed downwards, then it does not have a DPF. If it point out straight, then it does.

    There may be a new law coming into force next year where diesels are subject to a full emissions test, which would mean the removal of the DPF would mean your car would fail.

    I got rid of my DPF and had it mapped out of my ECU whilst also having a remap which gave me the extra power, but if the above law comes into play, I face a massive £1500 bill to get a new DPF

    Hi,
    I've got a 535d e60. i've had it re-mapped and i was going to put a straight through downpipe in.
    by doing this it would remove the dpf.....yes??

    how will the car react by doing this post re-map......would i have to get it re-mapped again??....or would it just mean a standing alarm on my car??.

    very temped to do it but if i need another remap i probably won;t bother......like you i don;t want to get into bother with the mot if laws change and run into £££'s to make it legal again

    cheers

    Removing the DPF without getting it mapped out of the ECU is pointless. The ECU will still "think" that the DPF is there, and will commit to a regeneration at some stage. This could lead to all sorts, so I've heard and read. So just fitting a straight pipe is not recommended, and a remap is offered with the DPF delete. Check out http://www.ecotune-scotland.co.uk/ and click on "other products" for more information, HTH.

    is that really true that if the tailpipe is facing downwards then it doesnt have a dpf?

    if i go view a fiew diesel 318d's or 320d's 55 or 06 plate, is there anyway i can tell from the inside dashboard if they have a dpf or not? like a dpf light or something?

    great guys, many thanks for the advice....all makes sense.

    you've saved me a few quid and a bit of car trouble

    yeah you are right.....it's fast enough already with the tt 3l diesel and remap.......i suppose if i want more i should have bought an M5!!

    Cheers

    hi Ronnie, its closed mate my "petrol vs diesel?" one :P banter got out of hand.


    if thats true about the downward facing tailpipe on the diesel not having dpf ill go for a diesel then over petrol as the only thing putting me off the diesel was the dpf and having to regen etc and replace
