The SCR Hose is not self sealing but you can empty the tank and plug everything if you don’t wanna work to remove it. If something gets in the hose after you’ve removed the SCR, it shouldn’t matter. I tried to completely remove everything I could; reduce clutter, extra lines and some weight I guess.


Jupiter is a good resource, reach out. helped me some.

Thanks for the info - ended up not having to bother with the downstream sensor, but cut the closer one. Capped that, the post-SCR O2 sensor, and the SCR hose with vacuum caps and heat shrink, and a hose clamp on top of that on the injector hose.

Yeah I definitely put some thought into removing everything, I generally prefer that route instead of the hack job method. But my car's been down for over a month now (not for this, the delete was a "well while I'm here" thing) and I'm eager to get it back on the road, and didn't want to bother with pulling the bumper to get the tanks out.

Just about done with mine and need to figure out what to do with the two sensors in the midpipe section, #7 in the diagram here:

Attachment 1


I'm assuming they're temperature probes, and they're very stuck. Can I just cut them?


Also, I've removed the SCR injector at the hose disconnect and will be removing the control module behind the headlight. Is that hose disco self-sealing? Wondering if I need to plug it.

Appreciate the support. I was out of the country and just now seeing this.

That’s all good info. I would try and go back to plugs and disconnect before cutting. If you can get some, Kroil is a much better penetrant than PB Blaster, but you’ll likely have to go to Amazon to get it.

As for the nozzle, I just zip tied it up to a bracket on the side of the trans. Didn’t want it hanging. I’ve since removed the forward tank and SCR module so I might get back in there and try to remove the whole nozzle. You can get the drivers side DEF fill and hoses as well. That tank is integral to underbody splash guard attachment though, so leave that one. Mine was empty so once the hoses were off it, I just left it in place.

As mentioned, as much clutter, weight, and dead parts were removed as possible.

Good luck. 👍🏻👍🏻

Ahhh guess I was too late. Sorry about that, but I also know the feeling of just trying to get a job done! Hope she runs well for you!

Last week switch from Tunezilla Stage 1 to Stage 2 tune. Exhaust plumes are easily doubled to triple even though only went up in HP by 20. Noting this to see if anyone has this going on wasn’t expecting this much more exhaust cloud especially between 3500 and 4500 rpms. I wonder if it isn’t getting enough air. Entire back of car has layer of dust after a dew days.

[XxBBVTMxX]

believe this is normal. Mine gets dirty after 3-4 days, noticeable around exhaust exists. But, I don’t roll coal unless I floor it. And it only happens for about 2-3 seconds.

Also wanted to share since I decided to upgrade my exhaust manifold. Loving my SAV even more now.

Good evening, where did you get that header and did it require additional tuning. Also can anyone offer some help with the bimmertune egr delete, I can figure out what hardware that came with the kit is used to plug the very rear coolant line on the back of the block.

On the back of the block, use what looks like an oil drain plug from the kit.

If you email Bimmertune, he’ll respond with more detailed pics.

I got it from Europe. It’s made when ordered, so you have to wait just under 8 week to have it delivered. Check it out at

And yes, you need a tune for it or you’ll get a CEL.

Doing a full EGR delete, what do I block the port on the head with? I don’t seem to have anything in my delete kit

You created your own post, then posted here. Please don’t post all over the place.

Your engine designation is N57D30A, and you purchased the wrong delete kit. This is the one you need for your engine variation…

Looks sweet, nice upgrade and probably fits nicely now that EGR/AGR deleted?
What does this upgrade do exactly?

-less restrictive expelling of exhaust gases
-faster pickup for my Stage 2
-nice sporty sound for a Diesel

Ooh cool
Switched from Stage 1 to Stage 2 recently and really enjoying it, had some potentially serious problems but got em sorted because added a high flow air intake that required MAF sensor scaling/programming and got all kinds of limp mode and rail pressure low warnings, plus exhaust cloud way too much, but fixed it with going back to stock but had to do engine adaptations reset used AI help.

Something else to consider: I added the Darkside Intercooler- kept that highly recommend. Slightly firmer acceleration performance gains IDK but def peace of mind with IATs confirmed 25 to 60 degrees lower than before (I ran a ton of bimmerlink logs).

Thx for this..

How did you get it tuned? Unfortunately my tunes from tunezilla are off the shelf so not sure of who to go to to get fun add ons like this tuned.

[XxBBVTMxX]

I got all my stuff from Darkside. Tunezilla for tune. I had zero issues with my tune. If your vehicle is tuned, you’re good to put on an aftermarket exhaust manifold.

What air intake you have that you had to calibrate MAF?

It was Darkside 3.5” induction kit. Cool. Personally not for me in luxury car. The turbo sound in cabin was way too loud. Add to it..On a date night with windows up no good. After return to stock realized I heard turbo slightly in cabin from engine bay (thought it was from exhaust previously) BUT with stock you the pleasant diesel chug louder than turbo whistle which I like, whistle (or spool?) is there but subordinate acoustically to diesel chug.

Btw I did get the tune / calibration for MAF scaling with the 3.5” intake but it had several error codes (related to air intake plausibility, we thought it was boost/intercooler leaks but no leaks actually) so we reverted back to Stage 2 tune. That’s when the low rail pressure codes and low pre feed pump and limp mode saga began. Turns out engine adaptations probably drifted and the reset fixed. Major relief because mechanics couldn’t figure it out and all they want to do is trial and error start replacing pumps, sensors etc etc etc and coulda be $6000 down the drain if AI hadn’t help steer me onto reset DDE adaptations.

Used Bimmerlink logs a ton, ran tests, fed data into AI for analysis and did again and again until confirmed fixed. Amazing

I posted in the F10 forum on the recommendation of someone else given not many e70s (and none in the us I believe) were released with the N57 engine

Also, the kit you linked to isnt the one suitable for the N57 with the transcooler. That kit has no connector pipe for the transmission lines

To answer my own question, you do not need to blank the port with anything as it only communicates to the EGR port on the front of the engine which has already been blanked off.

In the end I decided to keep the transcooler so it wasn’t an issue in the end.

I don’t understand anything you wrote. To receive better help from the community, post on the correct forum. ✌🏽

Sadly....after unloading the groceries, i drove over a rock which managed to slice my wheel and tire FFs this is why i cant have nice things, not even 24 hours with it and now i gotta replace a tire lol

Had my 2015 35d deleted last year. I see some of the smoke coming out of your exhaust in the sound sample above. I’d like to know if there is a way to cut down on the smoking, mine will put out some significant smoke when I’m at park and the car is idling. Is there a tune or fuel mapping update I need to do to cut that down? Other than that I’ve been really happy with it. It is a bit embarrassing when I smoke out restaurant patrons outside when I run in to pick up some food.

Do you happen to have an exhaust audio clip you can share? Would be awesome to hear what it sounds like to have the performance exhaust manifold (or header?) on there. I assume you kept stock muffler and no added resonator? If so mine is pretty similar less the exhaust header. (Stage 2, stock muffler, added DOC Cat). That aint a cheap upgrade parts $1800 min plus probably tariff now and labor wow. But probably cool. Hope the extra pickup is very noticeable. Bet it sounds very cool!

Tempted to delete muffler for more sound but have a feeling too much for my taste in luxury car… header could be sweet though…

Also I didn’t like the3” performance air induction pipe and too many error codes, turbo whistle too much over engine but did get a performance air filter… seems nice/very modest sound and response gain maybe.

Mine doesn’t do that. Had some problems when I did 3” air intake but removed it later and fuel was very rich and exhaust clouds like that. No one could figure it out. Ran tons of live data tests and fed into AI until figured out air/fuel learned adaptations were probably drifted.

Did a reset of engine adaptations and kept running tests and exhaust clouds went away while parked and revving engine basically none. Now just a sweet plume at mid to full load or launch which is fantastic for many reasons.

Look into adaptations reset and see if that’s a good idea… let us know what you find!

Edit: also I didn’t have that much exhaust at idle. If reset doesn’t work consider adding Diesel oxidation catalyst to down pipe (I believe that’s where it goes)

[XxBBVTMxX]

No, unfortunely I don’t have a sound clip. And these days have been crazy windy so it would be difficult to make one right now.

I have all new piping, DPF downpipe delete and the resonator that Darkside sells, and a new less restrictive muffler from vibrant with dual exhaust tips.
