F30 (N55): Drivetrain Malfunction/Misfire

Carbon.F30 · 08-24-2019, 11:05 AM

F30 gang: drivetrain malfunction & loss of power. I had what felt like a cylinder misfire last week and seemed to be losing boost yesterday. Frankly, it sounds like the typical blown/cracked chargepipe but I have an ER chargepipe so that shouldn’t be an issue here????

Note: full bolt on, with MHD Stage 2+ tune.

Any thoughts?

Similar happened to me - unfortunately they couldn't diagnose the error

Hey,

I finally got around to scanning the car, here are the codes that came up:

DME ACTIVE CODES:

120308- CHARGING PRESSURE CONTROL, PLAUSIBILITY PRESSURE TOO LOW. 1FBD08

DME SHADOW (INACTIVE CODES):

- 1FBD08 - DRIVING READINESS: MSA DEACTIVATION REQUEST FROM BDC.

Thoughts?

Did you end up figuring this out? I am on a custom tune off of MHD and my symptoms are on cold start (first start of day) my revs will dip low then pop back up. Almost as if it is about to die. Then the rest of the day no issues. Clear code it goes away.

Did you solve this issue?
