Here is a Carly deep diagnostic of all control Units... I believe they are almost all related as it went from the 2 o2 codes to 35 in an instant...

Sounds like the PT bus and or Flex ray bus are having communication issues.... the no power at Terminal 15N is where you should start, think has something to do with the power distribution box in the engine bay.

You said it all started with o2 sensor short circuits I think? Always start simple check all fuses for the car. one little thing can daisy chain pretty quick in these cars. also just saw that you power steering module and electronic damper is not communicating and they get a signal from Terminal 15N. look into that

The lpfp has a module that runs the pump, that sends and receives messages over the PT bus. so if the bus has issues, OBD2 live Data will no show right. probable solving the bus errors with fix your wierd fuel readings

Exactly what I said to friend last night...Oddly I didnt see that fault on Carly only the sendable file and as soon as i saw thatit made sense...

scan it with ISTA+. Let me know if you need help. Have you tried removing the JB4? JB4 shorts will cause these issues.

no i uploaded our convo from 2 days ago where said flexray bus is responsible or most o the other codes...

And o course I removed JB4, reversed all coding, Loaded Bootmod3 stock map, did plugs, reset dme, battery is new, switched around coil packs, tested fuel rail pressure...all the basic things just to rule them out

The specialist will do ista...and ill take ur advice since enzo didnt getthe dme i will have bootmod3 remove tamper code go back to dealer for puma and istep updated...

Also important to not Navogation is not working Found a threa her ewith EXACT SYPTOMS eneded up being telecomm box...$500 new, found one used or 250....Have to ind where it is ...thats also causing emergency call malf SOS...

[DKX4///M]

the 02 codes, who knows maybe i shorted jb4 and somehow send voltage to a dangerous part o dme...

FWIW, somewhere on here I read about spark plugs, specifically how the OEM ones are the way to go as opposed to the commercially available equivalents. I was always under the impression that it really didn't matter, but this thread convinced me otherwise. May be in the 1 Series side of the house and was N54 specific as I recall. Just a thought.

I learned early the plugs are VERY SENSITIVE to damage and Correct Installation...I have a nice Torque wrench and gapper and ive done them 3 times now no issues...

U may be right ...def no improvement w colder NGK Plugs, just heavier wallet LOL
