They are fine just hanging there and left un connected. They go to a pressure transducer to help ECU decide when a regen is needed. The tune makes ECU not care about this differential pressure reading across the DPF. Essentially, there is no differential pressure anymore if DPF has forgotten its ABCs.

So got new delete pipes installed and had ecm delete done at JR Performance. She won’t start getting the U0100 code lost communication with ECM. Will try and reach them tomorrow. Maybe a syn issue?

Check your ECU connections, this is the #1 cause of no starts after tuning. The rocker arm should be fully open before inserting the connector. See this video:

Thanks for this write up!
Finally getting around to getting mine done. I’m just gutting the DPF and deleting the EGR (tune is sitting waiting for me). My question is with the wastegate; OP just removed it and plugged the port on the turbo. Is that safe to do? I’ll reroute the coolant and vacuum lines but what about the sensor in the waategate itself (looks like a temp probe but I’m not sure). Thank you! |

Hi, I have same “no start countdown” on my 2011 X5 35d. I was hoping to do just a tune to turn off scr and egr like you described. I’m curious in your case after your dudes tune how many miles were you able to drive before your dpf gave up the ghost? Thanks |

Guys, i saw a thread/post where guy replaced lower turbo on completely stock emissions/dpf still intact, picture was with turbos and manifold out and dpf just hangs in there by itself. If someone can send me this link it will be very much appreciated!

Just like everyone has said, this thread was super helpful so far. Was able to get the DPF out and didn't have a hard time getting the 4th bolt from the motor mount. Was able to fill around and drop the socket in while pushing the DPF up.
Just need to do the EGR delete and should be good to go. |
