Hello, I have successfully Deleted my 2015 535d, I gutted the DPF and the SCR AND removed both EGR´s completely also removed the swirl flaps and DEF tank, cleaned my intake manifold and walnut blasted the cylinder head.
The Tuning was done by DUDMD.
I***8217;m going to cover mostly the Removal of the EGR coolers and the coolant lines, since I couldn***8217;t fine any info online, the rest was gutting the DPF and SCR there is lots of info online, there is no need to remove the engine mount to replace the DPF unlike the 335d.
Took a lot of research but it went flawlessly, ordered 2 different EGR delete kits on eBay but they don***8217;t exactly fit a US car.
First I ordered this kit.
https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/173729214904
This is what comes with the kit:
It looked good until I realized that there is not cover/plate for the intake manifold.
Also there is not plug for the cylinder head coolant port.
Then I ordered this kit.

This kit does have the needed cover for the intake manifold pipe mention above also has the plug for the water pump port and the cylinder head port Kind of ***
So this cylinder head port cover is not perfect fit, the plug is very short, although I could of make it work using one of the longer machined plugs from the first kit I ordered but instead I used a hard plastic OEM plug that I seen online while browsing pictures of N57 Cylinder heads, I was a little worry because nothing holds this OEM plug in place other than the 2 -O rings, but it has been there for couple thousand miles now with no issues and it was $4.76
Part number 11-71-8-518-878

So Now since I want it to remove both EGR***8217;s I need a different block off plate to go on the exhaust manifold, I contacted Sebastian Work shop the seller of the kit, and he had the block off plate built for me and that worked great! After that he post it for sale of eBay so now you can get it from him or have a machine shop make one for you.

Now on to to the EGR Cooler hoses/lines:
There is 2 hoses that come off the big hose tree right off the water pump, a feed and a return, it goes to the small EGR cooler (Attached to the exhaust Manifold), from there it T off to engine block and it goes to the Urea Injector and back to the water pump tree
This is the coolant tree after I capped the 2 lines with this 2 OEM blind caps
17-12-8-515-062 $5.98
11-53-1-436-850 $5.93
It already had 2 caps in place, I removed the 2 hoses and added 2 new caps.
Now the Connection to the engine block:
This line needs to be removed and there is a OEM bolt and sealing washer that goes on its place, the block actually has threads for this already!
Water Plug: 07-11-9-904-539 $1.67
Sealing Washer: 07-11-9-963-225 $0.40
Have your bucket ready to collect coolant when you disconnect this hose
That take care of the coolant lines, it took a gallon of coolant to refill on my car.
All the vacuum lines can be disconnected and capped at the source(driver side by oil
deep stick)
DUDMD took care of the tuning, the car runs very strong and smooth, there is visible smoke at WOT but I***8217;m ok with that, I left the DOC in place to help with the smell.
Here is all the parts that I removed
This is what it looks like, she***8217;s all stock
