Kind of a Big Deal

Gentlemen, I have been lurking on this thread for some time. I have a 2011 335d that is coming off warranty one year from now. Based on the excellent postings of TDYwyse and others, I have been formulating a course of action for my car. Let’s see how carefully I read your comments.
Based on the thread I have concluded that: - Blocking off EGR is straightforward especially if done on the intake side. Benefits include less CBU and better mileage. - Blocking off the EGR will set pending and permanent codes if they are not cleared after each ride using BT or Torque or BMWhat. - The tune installed by Ecotune (via their NJ subsidiary, Redline Speedworx) suppresses those codes. - But if you have Ecotune you can just turn off EGR therefore no need to block off EGR in the first place - Ecotune does not require DPF removal but it can accommodate it if desired in a later stage. - Ecotune’s DPF removal procedure includes removing the DOC and replacing the whole thing with a different downpipe. TDIwyse notes that the DOC performs certain beneficial functions. Questions: - Anyone care to share the approx. cost of an Ecotune tune install? Is it a “while you wait” deal? Will they repeat it if my dealer installs new system software? - Anyone have any idea if the EGR suppression will be visible in the Washington D.C. emissions inspection? I have been told by a fellow diesel owner that the inspection is cursory and is limited to an OBDII scan. - Does anyone over here choose Ecotune’s “Envirotune” option i.e., optimizing mileage and reliability vice power? Thanks all! James Last edited by Persian Whisperjet; 10-13-2014 at 02:42 PM.. |

to this point, NOBODY has a tune for EGR delete or DPF removal that will pass an OBD scan, though one tuner is supposedly getting close. |

Doubt anyone will do it as a while you wait deal, unless you wait a whole day. Ecotune is in Scotland, btw. The word is, most tuners for a small fee will flash you back if your dealer flashes you to stock. It's the downtime/wait you have to consider. |

Forgot to post this back in the end of August .... Latest UOA was with the Ecotune deletes using Mobil 1 ESP 5w-40. It had a lot of stress with lots of full power testing and was also in the crank for the 11.8 second 1/4 mile pulls.
Shell Rotella T6 5w-40 is in the engine now.

OK amigos Lenny couldn't come to PR due to personal reasons, I did go under the car cause of suspected leaks but when we investigated there were no leaks whatsoever anywhere, no carbon buildup no noise an car was running , we didn't see or hear any issues around the turbos either

Ha. Yup.
Hey, did you ever get around to the pre-turbo EGT probe? If so, do you have any comparison on the pre/post EGT data?

During inspection for leaks, the downpipe to midpipe connection is actually touchable with bare hands. I thought it would be hot as fire. Turbo end (forward end) was completely a different story. |

All, JR at Redline Speedworx in New Jersey emailed me today to say they are no longer an Ecotune dealer. Are people dealing direct with the home office in Scotland? Thanks, James
