You can search and find a lot of threads on the subject but when they are talking about code-free the code(s) various permutations codes set when the ECM thinks the DPF is full. When the ECM thinks the DPF is full it tries to clear it with what is know as an active regen. During active regen the computer injects diesel on the exhauste stroke in order to send it to the DPF. Of course you no longer have a DPF so this means the diesel vaporizes and exits the tailpipe as a cloud of white smoke.

This is where I am at and I will be removing the EGR soon but that is not going to stop the active regens every couple on minutes once the engine is up to running temp.

Compucowboy,

My PMT will not clear the DPF codes. Clears other codes fine but not these. Are you sure the Edge will? I have read that it is a Starscan/dealer only thing to clear the cat full codes.

I am removing my EGR soon but if I could clear the codes I sure want to know because that is my main problem now.

I just got off the phone with BADP; Shane I think but I did not ask, and they (Shane) said the system cannot regen with the generation 1 box. I don't know where the periodic white smoke is coming from for sure and the PMT does not indicate regens. I assumed since the periodic smoke only started after the "cat full" and given that forum member kydodge said that he was having the same issue and his Edge was displaying a regen message then that that is what it was.

If it is not the regen and I have had perfect service from BADP so far and I have no reason to doubt; this is good news for me! I will get the gen 2 box which should solve the cat full and from what everyone is saying I should do the EGR (thanks for writeup Compucowboy!) right away and see where I am at with my problem.

More smoke. Some at idle with the dpf delete without the egr delete...I wish there was less smoke, it is only a matter of time that I will get pulled over for it...

I agree... I have to solve my problem or I have to go back to stock. Black during acceleration is not a problem. White sitting at a light is not.

I found my problem. An EGT sensor was not hooked up. Soon as I corrected it and drove the cat full percentage started dropping 90%, 80%, 70% then not reading on the overhead. Once this happened I pulled over to the side of the road and cleared the code.

The smoke I was seeing was from regen. Once the code was cleared it stopped. The code could not be cleared until the computer thought it was successful in clearing the cat.

ok so the smoke yall are talking about is it black or white smoke from it thanking its in regen still?? i am really confused on all this

There must be an algorithm in the computer that uses the EGT probes to determine in part when the thing "must be getting full, I better clear it..." with all the probes hooked up it thought it cleared what did not exist and then and only then could I clear the 2 codes P1451 and P2463.

Now I only have the typical P244A or "pressure too low" code that is being addressed with the gen 2 box. Trust me everyone is thankful the regens are gone :thumbsup
