x5 35d SES codes - NOx sensor

[Stockx5]

Well there are no known complications with DUDMD's tune.

I was just expressing a hypothetical concern. based on my very bad experience with the tune from bawareca. I tried looking for the thread I read a while back on e90 and can't seem to find any such case where the tune was not showing errors. So maybe it wasn't what I thought it was.

one way to know is if one of us will just unplug things like an injector or a maf sensor. see if the errors show up.

I think you are still better off with the tune and the slim possibility of having a rare code that does not log vs all the variables the existing emissions system has and the cost involved in maintaining it.

Logically speaking you're right here. If my front NOX sensor has failed, it's no longer a matter of IF the rear one does it's just a matter of WHEN the rear one does. Not to mention all the other emission systems that are prone to failure.

I've had the cats removed on my truck which causes 2 codes to appear. The tuner went in and programmed just those specific codes out so it has no effect on anything else. It's probably a bit more complex here, but I would hope it's the same general principle where they tune out only specific codes leaving all the others.

I'd still like to run the potential scenario past them and maybe get some more insight on their process. I may be blind here, but I can't seem to find any e-mail address or contact us link on their webpage. Does anybody have their e-mail address?

I’ve chatted back and forth with the owner of DUDMD tuning a lot, and it basically is the same principle. Monitoring and codes for just the emissions parts that are removed are blocked. Then you also have some tweaks to the tune maps to get more power if desired (do it!).

You can find DUDMD Tuning on Facebook. Message them. Dmitriy will gladly answer your questions and put your fears to rest. He’s great to work with.

Reviving an old tread here, mainly out of excitement. It's been a struggle finding someone willing to take on this task. No shop wants to touch it after the whole VW emissions scandal, not even off the books. I've talked to probably 20 different people in 3 provinces with no luck. Through a friend I got connected to a mechanic willing to take this project on. And he's local. He's the head mechanic at a non-bmw dealership and builds drag cars on the side. He's looked into it and said it should be no problem.

I also see DUDMD now offers remote tuning via OBD2. Being Canadian that option is HUGE since I will not have to ship the DDE back and forth over the border.

Now I just have to decide between the buzzken kit and the unobtainium kit. From the fitment issues I've read on the Buzzken kit, I wonder if going with the unobtainium kit I will come close to breaking even between the 2 with less labour and welding involved. And if the difference between 3" and 3.5" will make a noticeable difference.

Diesel ops has a cheaper option at 600 for their down pipe + midpipe. Appears to be of good quality and is bolt on

https://www.dieselops.com/orion-dies...-x5d-2009-2013

I would have gone this route if it had been available.

BTW the afforementioned issue about the tune that caused all codes to be deleted is specific to BPC. There is a big discussion about it on facebook group about multiple cases. with BPC claiming it was a bad batch.

DUDMD confirmed their tune does not interfere with non emission related codes. I highly recommend their tune as it alleviated all my tune caused issues.

That price is pretty impressive! The quality of pipe definitely looks much nicer than the buzzken kit too. But there's absolutely no info posted on the dieselops site and the part doesn't exist on the Orion Diesel site. Although I do see them doing testing on a 335d with an offroad looking x5d on their facebook page. But not really any info there either. Have you seen any reviews on it?

I chatted with DUDMD as well, and he confirmed to me they don't turn off the entire fault code table. I'll be going with them for sure for tuning. May not bother with the remote tuning because it still involves shipping cables and dongles back and forth. At that point may as well spend the 10-15 minutes and pull the DDE.

EDIT: I see the Orion kit is 409SS like the buzzken kit while the unobtainium kit is 304SS. With that said... I could buy 2 Orion kits with the egr delete for the cost of 1 unobtainium kit, so even if it doesn't last as long it's probably still cost effective long term

Chatted with one of the guys at dieselops today. He says they've put on about 10 of these in the shop and so far zero fitment issues or leaks that require welding. Replaces all the pipe from the turbo back to the muffler. The kit does come with the EGR block off plate as well. Sounds like a no-brainer to me, placing the order for this kit today.

So I guess my next question is, aside from the savings of 5lbs or so, is there any benefit of doing the EGR race pipe and removing the EGR cooler completely since it will already be non-functional with the block off plate in use.

One of the most obvious benefits of removing the EGR cooler is eliminating the ingestion of exhaust carbon through the EGR cooler. But since you already have the block off plate then it would eliminate the possible hack of finding suitable hose for routing the coolant.
