2012 x35d tune without removing SCR, DPF and EGRhardware

[Gulfsurfer]

I'll be doing a full delete on my 2012 e70 x35d later this year (SCR, DPF and EGR). I'd like to kill my active tank CEL error 49E1 which is present due to a faulty active tank heater element.

No, it doesn't get cold enough here to freeze 35% urea solution. I wish I could just hack the heater element test protocol but i haven't found a way. No, I don't want to send $250 and 4 hrs of my life to fix something that I will take out later this year.

If I ship my DME and get it coded but run it with all the SCR, DPF and EGR hardware installed, is that an issue, will it throw CEL errors until I do the hardware delete? I'm trying to kill CEL lights unless they are not related to the SCR, DPF and EGR systems.

Second part of my question: Stage 1 or 2? I'm looking for longlife not necessarily performance, but if the engine longevity isn't significantly affected by Stage 2, I'd go with Stage 2.

thx!

I don't know who you are going to use for your tune but on my previous 09 X5d I had a JR 2.8 tune (full race) and also full delete. That being said; you're still the one driving the vehicle, just because it's tuned doesn't mean it's going to beat on itself. It will still be just as reliable as it was ever going to be unless after the tune you take advantage of the additional power and beat the hell out of it.

Anyway, we put 125k miles on our after the tune and never had a single issue aside from general mainentenance stuff. I sold it with 225k on it and last I heard it is still running strong for the next owner. I would go with whatever tune you can afford. If you can afford the highest level, then get it.

Personally, I have a DUDMD tune. I know of people that run the stage 2 without deletes- at the minimum, you should ask the tuner to turn off the egr until you delete it. I'd ask the tuner what the cost would be, such as just paying for the upgrade/ flash fee from the original tune, and then go from there.

Honestly I think this is a question for the tuner of your choice. I've put about 35k miles on my X5 since the delete in May '19, and it's been great. I know it's not the absolute cleanest tune, but it was half the price. It puffs a really small bit at idle, and hazes just like they all do at absolutely full throttle, but there is 0 noticeable smoke coming out of the tailpipe while driving normally. Dmitry is very open to discussing your best options, so I'd suggest giving him a call or a facebook message!

Excellent point, ty. I'm pretty easy on the throttle, Mostly highway commuting.
I do some towing but for the heavy work, I've got another diesel, twice the displacement, so I'm not going to be pushing the x35d to it's torque limits.

Yes, DUDMD was my intention. Ty, I will call him. I'd prefer to have the DME coded once only. I would expect that the EGR would be turned off by default, but if it needs to be blocked off, that delete is the easiest, least time consuming of the three. So I could do that right away.

Hi,

I’m thinking of ping the same tune first and delete later. Were you able to do it this way without any issues?

Thanks

I purchased my e70d with the Stage 1 tune from DUDMD with the DPF disabled and it runs fantastic. I will be re-tuning later on with a full delete just waiting on parts.

Any benefits to removing the equipment vs leaving it on aside from the weight loss an additional power?

If your tune disables DPF regeneration, which it would if it includes DPF delete; then your undeleted DPF would rapidly clog up very quickly.
