5mbar is a good idea like the thread says, you see which hose he tapped into. You might not need to force a regen if your dde is asking for it already.


Extended BMW 335d PIDs for Torque

This thread has the custom pids you can add to torque app to see differential pressure of dpf, etc.

I believe hes grabbing the line in front of the very last line, i just dont know how hes reaching it, does the plastic block which the sensors sit on come undone?

Update
Got ista, hooked up a sacraficial hose, ran the differential pressure test and punctured till read 4-5-6 repeated as it wouldnt remain constant, send a regen signal, drove to work and back 50 miles, got home noticed alot of soot where the hole is punctured, im hoping this is normal and got a light and reduce power untill i key cycled the car. Generic codes were p323f and p045e earlier i saw a mass airflow sensor code so im going to investigate the charge pipe

The soot would be expected. That line taps off on the exhaust side of engine after the turbo and before the dpf. I'm surprised it doesn't get so hot it overheats the rubber... I guess most of the heat gets dissipated by the time it touches the rubber parts?

MAF could be charge pipe, or if you accidentally disconnected the CCV lines, etc you get the idea with the air leaks what to check for.

I did smell a little burning rubber smell, the red charge pipe ur refering too correct. Cant find an aftermarket one so im guessing oem

There's an aftermarket lower pipe BMW 335D Upgraded Charge Air Hose for Stock and Upgraded Intercoolers

I was planning on getting it for a future chipping which runs more boost... Want mine for 100 shipped? Otherwise I'll just wait until it leaks

Something felt off while driving and noticed the hose to the dpf had burned through, replacing and retrying with a thicker hose

Update
Regens seem to be taking place, noticed a few smoke clouds at WOT, i do have CEL still on though but havent gotten any reduce engine power notices in a while
The generic codes are
P0101-MAF
P323f-?
P045e-?
P02cb-looks like an underboost

Any help to track down and remedy my situation is appreciated

Did you put back the lines as normal? It may take a while for things to settle back. If you can check with rheingold or carly, thebmw error codes would help us diagnose as they are more specific in description

I used another thicker hose and repunctured, im still learning how to use RGold but a list of odd errors are coming up where its saying it cannot communicate with radio etc, i may go ahead and purchase carly to help
