Many thanks LFW Bow down
Don't want to take up too much of your time but for when I speak to them do you have a brief summary of the issue of leaving butterfly in V's removal and physical blank? I have said that I had seen a recommendation to remove along with the stub pipe (not sure if same thing) which is usually all coked up and "allows the engine to get more air/breath easier..". He said "makes no difference whatsoever"...? Rolling Eyes

I don't believe the butterflies are sufficient to prevent airflow when simply left in uncontrolled. If the valve is open/partially open anyway, which it often is when they fail, it does nothing to resolve the problem except to remove the MIL. Thumbs Up

The stub pipes are in the throttle housing. It's not a huge restriction and I wouldn't think removing them would make a great difference (but in theory, yes, there is a difference). They could be cut off if you wanted to remove them but leave the pipes. Wink

For clarity, the other butterfly is the one in the throttle body which closes when the EGR valves open. If the EGR valves are blanked and this closes, you'd get a vacuum which could cause some serious damage. Thumbs Up

Update:
Had works done yesterday to blank and 'take out' EGr's from software.
To clarify they did remove the butterfly. The method of blanking was to flatten the existing pipes rather than put plates in (im not clear on which 'pipes' - maybe the stubs?).
They did say that there may be the odd spurious 'fault' that pops up - which it did more or less immediately after driving off Exclamation fault code was 409 (something about emissions on the high side) - I have to get this one cleared when im back over there so they can download the fix and clear it; Im told this is a "false fault" as the EGRs no longer exist really but just hope the blanking procedure is adequate..?

Also got some kind of re-map included which does feel a bit sportier I have to say - definite quicker pick up on acceleration Shocked

well that makes it a real Censored if you ever need to put it back to std for whatever reason. Cant understand why they didn't just use the flat blanking plates in between the EGR and the pipes?

I also don't understand why you would still get spurious faults if they've software mapped it out properly?

I never had any faults with mine when I did it on Monday

I do have that feeling that things don't ring quite right..
Surely if they used the correct map-out (is there a specific one that should be used - post 2008 models?) then no faults should show - however the engine management light is shining brightly Sad
As I said it is fault code 409 if anyone knows this one - Im just wondering if it is something that is likely to cause any issues/damage ? Im told not as the EGrs don't exists anymore but the ECU obviously doesn't like it...
Bit P'd off if the pipe flattening is going to cost me large if I ever need to put back to original for the sake of a couple of plates Big Cry Is anything likely to flow through if not a true seal??

Presumably it's this one?:

Sad

There's no set map to be used. It's a case of modifying the existing software and requires great expertise. Clearly it hasn't been done correctly or you would not have the fault and engine MIL. It's actually only a single bit of the software file that needs to be changed to remove the EGRs. Wink

I believe crimping the pipes has certainly been done before and should hopefully be OK, but it's a bit of a messy solution.

You have to be careful with some of the so called egr delete maps, as some are offering this service and all they are doing are deleting all the codes, so what you get is no warning at all, if there is a real problem..and at that price like LFW says it sounds to cheap.

I had my 2008 D3 remapped a year ago by Mike of Dynachip (lots of good comments on D2 forums, eg here).

I paid £225 for the remap and £25 to deploy a code or command to permanently shut the egrs and diagnostics allegedly confirmed no operation of the egrs afterwards.

I appreciate that yours may well be a different animal due to the dpf thing, but I have been very happy with mine since it was done.

Lid, no UK spec D3s have DPFs, but with a DPF fitted, EGR blanking is currently impossible all together. Thumbs Up

Any update on this - is it still working?
I've got the engine light and P140A code on my 2008 D3 so need to find a solution.

Problem is, that when the ecu is updated, you're more than likely going to need to do a lift pump reset on the vehicle, so it won't help you really.

I'm coming to Ireland in a few weeks and can do that for you if that helps?
