I’ve used ista before this issue and had no problems with communication

[E90CAMERON]

So I went and changed the jbe and still nothing. I starting to wonder if a mouse got a wire or something as everything is plugged in no blown fuses I just don’t even know where to start looking for that

[TunafishE93]

Do you have power to the JBE? That is where i would start..

Here is that screen it’s giving about turning the ignition to clear faults before

So I got my ista figured out and it’s reading now here is what I’ve got now

NOW we're able to diagnose. ALL your modules now appear, & only the VTG (Transfer Case Module) is NOT communicating (possible fuse issue or Bus issue). You actually have a 335xi (AWD or X-drive). You have 35 Fault Codes in Fault Memory.

Please attach ScreenPrints of ALL Fault Memory. Although we are particularly concerned with DME Faults, since you have "Crank, NO Start" issue, please attach ScreenPrints for ALL 35 Fault Codes. See "Fault Memory & Test Plan" pdf attached to Post #14 above for procedure, & see "VIII Saving/Posting ScreenPrints" at bottom of page 8 of that pdf, for HOW to post legible ScreenPrints (also easier for YOU to read if you SAVE your Scan Results).

Ok so I figured out the the dme plugs were not right. So I believed it shorted out a few sensors which is why I don’t think it will start here is the be codes and this is all that comes up now

I'm replying to your 2:20PM post (which you changed). You apparently have a major wiring harness "Pinch" where the
harness has been shorted to B+ (possibly at rear of VC or something else you Removed & Reinstalled in that repair.
ALL of the major DME Faults that are Currently Present were saved at 163,152 miles (is that what your Odometer currently
shows?) or 262,568 km.

Attached are ISTA ScreenPrints which show the wiring & location of the Throttle Valve actuator (2 faults), Intake Air Temp &
Boost Pressure Sensor, Intake Pipe Pressure Sensor, Low Fuel Pressure Sensor & Rail High Pressure Sensor. Follow the wiring
from those sensors to the DME, & you should find the pinched wiring harness which is the cause of those "shorts to B+".

I don't have an N55, so can't help with locations of wiring harness. If you need to use "ISTA as Shop Manual" to see wiring,
Connector Locations, or Connector Views, see the attached pdf which explains HOW to do that.

I looked and traced all the wires I didn’t find nothing pinched

[E90CAMERON]

I went back through and anything that was remotely tight I made sure wasn’t and for pinches couldn’t find nothing when I cleared the codes I did get a little puff of a start but still cranks the battery won’t hold a charge since it’s till pretty cold here and the alternator obviously isn’t charging it
