I'm having major issues with the emissions system on my 335d with about 100k miles.

I want to delete the SCR,DPF,EGR all in one go.
I've been away from the forums for quite awhile, is JR AutoTuning still the best tune to delete all the emissions?

Can someone take a look and see if the below is all I need to delete these?

DPF delete:

EGR delete:
https://www.tunemyeuro.com/eco-bille...5-35d-aar2353/

SCR delete:
Could use some help here on the most cost effective and permanent way on this one.

Yes, that's what you will need.

Also there are other cheaper options that are just as good

Downpipe - https://www.vr-speed.com/vrsf-335d-s...-bmw-335d.html

EGR delete - https://*************************/co...placement-pipe - The Nazi moderators blocked the link.. look up Whitbread performance

Exhaust - https://www.atmspeedshop.com/collect...w-335d-exhaust

Tune- BRR is way cheaper than JR

Excellent, thanks.
I'm looking at the BRR website and I don't see the 335d in their store.
Is it custom?

Is the exhaust required for SCR delete?

BRR doesn't have a website yet, if you are interested I can give you his information.

The SCR can be gutted if you want to keep the stock exhaust, just cut a hole big enough and the whole filter element or whatever you want to call it comes out, some people cut a smaller hole and start cutting chunks out of it until all of it is gone.

Just adding to this post. Here's the guide I used to see where to cut to make SCR gutting the easiest.

Sorry to hijack, but is this basically the same in the X5 35d? Obviously slightly different parts. Cost-wise, is it better to gut the SCR, or replace and resell the original?

Lots of people gut the SCR....pretty easy to do if you can cut and weld.

If you buy a delete kit for the x5d, which you should because it'll come with the second egr block off plate and It will have the scr delete pipe with it. This is the easiest way to do it, if you just buy a downpipe you'll still need a block off plate for the second egr and you'll have to gut the scr which mean you'll have a massive can that'll create back pressure in your exhaust. I don't care what anyone says but diesels don't like back pressure you want a free flowing exhaust. So I recommend deleting the scr all together and just sell it.

Is anyone able to run a stage 2 without deleting? I know Malone tuning offers this option.

Do you think I can also get a contact info for BRR?
Thank you!

Not going to answer that. You can check on cali smog website for more details.

I think sadly I know the answer to my question, just wasn't sure if any veterans in CA knew any work arounds with tuning etc... or had any alternate ideas to get the benefits in Ca with still being compliant....

[lnxguy]

Move out of California.

There are no work around. California has added cameras now to diesel smog shops.
