Does anyone know of a source for dpf delete pipe for the 3.0 tdi?

Yes, Les's set up is 3 inch. It eventually reduces down to 2.5 inch so you can couple to the pipe coming out of the stock muffler.

Hi, had DPF delete and Malone stage 2 tune end of May. All good for @ 600km and then would go into limp mode under sustained WOT while passing semis. Would also go into limp mode under low load but steady throttle.
Keep in mind, I was warned by Malone this may occur.
Had ECM reflashed and no more limp mode. But. Now the engine does a cycling of on/off power under sustained high load.
As soon as I can, I will be doing some testing to narrow down the root cause.
I will keep you all posted.

Mick.....that's not good. Don't get why WOT would put it into limp mode. I have never done WOT with my Treg. I guess I should try it and see what happens. Have never gone into limp mode since the tune. My tuner never told me that Malone said that limp mode was possible under certain circumstances.
I wonder if all tunes are the same in that the coding of the tune for my Treg is the same as yours?

Hi, not sure. Only Mark at Malone would know.
Are there differences between Canadian and US models? I have no idea.
I am sure there is a way to program these "glitches" out. I will gather more data and give it to Mark to generate a solution.
Maybe I'm just lucky??
Otherwise, I am happy with the tune! No more worries about DPF AND Adblue issues! It was going to cost me hundreds of dollars to repair my Adblue system. So, I put the money towards deleting it.
And it sure woke the engine up!!

I also had the DPF delete done last week and was never told to expect limp mode in any circumstances. I also thoroughly tested it in all kinds of driving conditions, including WOT, before leaving Les' shop since I had a 600 mile haul back to TN and didn't want any surprises. So far, I've not had any warning lights, and the car performed flawlessly on the drive home.
Only glitch I've encountered is once during a cold start, the engine idled a bit rough for a few seconds, smoked a bit, then all was fine. I wonder if their is an adjustment period where the ECU has to "learn" how to properly fuel the engine under what are sure to be new exhaust gas temperatures. Anyone know?

Hi, it does take a period of time with a certain number of key on/offs before problems show.
As an example, depending on a machines software, a sensor has to emit data out of range for a predetermined period of time before an error is logged.
The initial limp mode fault occurred with a WOT duration of 10 - 14 seconds and low engine load and steady throttle.
I suggest keep testing after some kms/miles have been put on.
There are a lot of differences between the USA and Canada. Weather, temperatures, fuel, and speed people drive, etc.

Hi, right now I only have the kit pipe with a resonator and the stock suitcase muffler. I do hear more exhaust and turbo sounds. I can hear a drone at 120 kph and may add a drone tube like Zagg did.
I plan on putting a different final muffler and tail pipes on at a later date.

Malone has been working on a stage 2 tune on my 2014; currently on the 4th upload. I got about 100 highway miles on the tune before getting the DPF dash warning. 10 minutes later, the DPF warning was replaced with both the engine warning and ECU malfunction and now car is in limp mode. 2 fault codes are both related to the DPF: Particulate Trap Bank - Efficiency Below Threshold and Diesel Particle Filter - Excessive Soot Accumulation. Following up with Malone, they say there is not a DPF delete tune available yet. I do a lot of city driving so there isn't much of a chance for passive regen. Without a DPF delete, I feel like I might be SOL on an effective tune. Any suggestions from members would be appreciative 
Those are the two errors I got when my DPF went bang. If you revert back to factory, do all of the errors go away? In other words, is your DPF actually clogging or do you have a faulty tune that's causing "phantom" error codes somehow?
You definitely don't want to do anything to damage your DPF, especially since you're only option would be to replace it without having a delete tune available, and it's one heck of an expensive part to replace. Also, be aware that if you live in an area that performs emissions testing as a requirement to maintain a current registration of your car, you can't do a DPF delete and keep your registration up to date. You may already know all of this, but I figured I'd mention it just in case.

I pulled the codes with my vagcom. Advanced measuring blocks for soot load... I think another member said its 08? I'll see if I can find it tonight. I'd think that I'd have to force the ECU out of limp mode for forced regen.
I was never able to pull logs with the last (fourth) tune but the third tune showed EGT at 890C. Mark was trying to get to 940C with an additional 1.75 PSI over stock. Not sure if that means anything substantial to other members.

Hi, by the way, DPFs can be cleaned. With tier 4 emissions affecting ALL compression ignition engines in NA, several shops have purchased a DPF cleaning machine.
Contact your local semi repair shop or heavy equipment dealer.
I have no idea of cost or turn around time at this moment.

I asked my dealer if there was a way to clear the codes and force a regen. on my DPF to see if that corrected the issue, and they told me "no way, no how". Whether or not that's actually true, who knows? That was what drove me to do the delete since my only other option was to replace the DPF. Hopefully someone else here will give you some better news.
I've been told by Malone that there isn't a tune available yet that accounts for a DPF delete for the newer 3.0 CR TDI, mines a 2014. Treg is in the shop now, I assume they will replace the DPF and possibly sensors under warranty. Moving forward, I will have to watch the soot load until a DPF delete is available.
