DPF Delete Pipe & ECU Reflash Source
 

Update Feb 2018: Further down the thread I describe the process. 3 years and 93,000 miles with this mod and 185,000 total miles on the X and STILL perfect with ZERO issues.

Disclaimer: For Off-Road Use Only

A source for DPF delete and ECU reflash is here: X5 35D Diesel DPF/EGR/ADBLUE delete development

Or, you can email Alex directly at: [email protected]

You'll have to sign a waiver to say this is intended for off-road use only and Alex will send you the DPF delete pipe and you'll need to send him your ECU to reflash. His shop is located in Riverside CA. He's making 2 additional DPF delete pipes with mine so he will have 2 more available very soon. Cost will be $2K.

I'll post a write-up when I accomplish this. I'll be sending Alex my ECU for reflash first and then when I get that back I'll remove the DPF and CAT myself and install the DPF delete pipe. Stay "tuned"! :)

Great news! I like the thorough testing that has been done.

I'd say, if the engine is still intact after this 500 miles, go for it :thumbup:

I want this so badly! However, I have two years under maintenance and warranty plan so I think it's best if I leave the powertrain as stock as possible until those expire. Then it's so on, though. I mean seriously, better mpg and more power...I'd be stupid NOT to do it! :)

I'd just be happy with a tune and some more turbo sound but I will keep an eye on this.

So, if one starts getting emissions issues post warranty, spending 2K on this may be cheaper and a better option to ensure the issues don't come back.

As Sheldon would say: "In what universe is sending your DDE to some random dude you met on a forum even qualifies as an option, let alone be a better one?"...

The Ten Worst Car Tuning Disasters Ever Recorded

Reminds me of that one time at Bimmerfest a few years back when one of those tuner showed up with a supercharged S65 M3. He was revving the engine when it blew up in front of the crowd...

If the exhaust issues prove to be reoccurring (knock on wood), spending 2k and be done with it may be a better option than throwing 1K every time just to see issues return. I personally would be afraid to ship my computer and ("nail-bitingly") wait for it to come back, but a vacation trip to sunny Cali combined with stopping by the shop may not be as scary.
That being said, I hope not have to do it.

Have you ever read "The Adventures of Pinocchio"?

:thumbup:

Hey, someone has to push the envelope on this stuff...

What does make me nuts are two things:

1. Tuners minimize the risks, or worse THEY dont understand the risks...

2. Owners who blindly believe salesmen...or look at the risk through a prism of other cars, other marques, other tuning efforts that took years to perfect.

Ive had a front seat watching some pretty amazing efforts, where people knew the risks yet pushed the envelop in a reasoned, planned project- ultimately to the benefit of many others. And seen the flash in the pan, dirty tuners with blown head gaskets and bent rods.

I go nuts when an owner worries "will this impact my warranty?"... I have total respect the owner that says "I could wind up buying a $20k motor if this goes wrong".

Anyone thinks a 'tune' is a 'thing' you buy, like a bushing or an exhaust- and that for the E70 all tunes are pretty much the same, or they tuners know all the limits- is kidding themselves

I dont know where Lambeau is on this spectrum. I hope he doesnt confuse the ready availability of tunes in the M5/m6 world for this being 'just another version'. 500 miles on one car?

Make sure you know what kind of player YOU are. ;) Its as important as the tune and tuner!
