Hello to all that reads,

New to be BMW, new to JB4, new to DIY. I had help on my previous post with a JB4 issue and cutting the diode and upgrading the firmware worked. It was running pretty awesome-ly until I installed a VRSF Charge Pipe/Lower and a VRSF 7' FMIC.

The first issue I was having was a boost leak, behold it was properly fitted and tighten enough.. problem solved. work like a charm for a while. Now i am getting all times of errors and looking for guidance and assistant. Just took my car to a shop that specifically deals with BMW but not "performance" they could not find any issues causing the error and offered a solutions....bring it back to stock and do more testing. Again, any input is greatly appreciated!!

some information:

2011 335 xdrive N55 M-sport -48k miles

Injen Intake
VRSF 7' FMIC
VRSF Chargepipe
JB4
I have a DP yet to install...would that help??

Attach are my JB4 settings and ERROR CODES (will be getting logs when i install the bluetooth). I set it up using the default settings from the n54tech site..

TMAP sensor damaged or harness damaged during chargepipe install maybe? Could also be a JB4 setting if it's set for a 3.5bar and you have a stock sensor.

Hi Mike, thanks of the response..it could be a possibility. However it seemed to be running fine after the installed it. would installing back in the old CP just for testing help. all this has just happened recently

my setting for set to "0"..is that correct?

Switching back won't tell you much. If you clear all codes ign on, engine off what comes right back up?

Hi Mike, thanks for your assistance. I went to double check any air leaks and saw that my charge pipe had lost a screw for the meth bung! I picked up a replacement from home depot. Boost is back and check engine light is gone ...for now.

Thanks again!
