CEL came on, reduced power... Help
On the way to work.. Taking off at a red light, CEL came on, lost power, Message came up about reduced power drive-train issue... . Turned around made it back home. Engine was struggling to idle at lights, shifted into neutral it would run smoother. Taking off it was way down on power. Sometimes it was like it didn't wanna shift, would let off the accelerator and then it would shift. around 30mph it would shake. I drove home slow and babied it...
So where do I start, to diagnose or look 2014 535i Msport RWD, N55 8-speed 110k miles These are the codes I am getting (Bimmer-link) Error Memory 140010 misfire, multiple cyl detected 140610 misfire cyl 6 detected 140001 misfiring, multiple cylinders, injection switched off 140601 misfire cyl 6 injection is switched off 11A002 High Fuel Pressure, plausibility, pressure to low 140510 Misfire cyl 5 detected 140310 Misfire cyl 3 detected 140210 Misfire cyl 2 detected 140410 Misfire cyl 4 detected 140004 Misfiring, multiple cyl, harmful to exhaust gases 140505 Misfiring cyl 5 harmful to exhaust gas 140304 Misfiring cyl 3 harmful to exhaust gas 140204 Misfiring cyl 2 harmful to exhaust gas 140404 Misfiring cyl 4 harmful to exhaust gas 140301 Misfire, cyl 3 injection switched off 140202 Misfire, cyl 2 injection switched off 140401 Misfire, cyl 4 injection switched off Info Memory 140011 Misfiring injection shutdown 231501 Error Memory entry: Send buffer full 11A401 High Fuel Pressure when injection is released, Pressure too low Permanent Errors FF1400 Unknown Error EC1406 Unknown Error |

Pulled my plugs to inspect them..
The plugs are about 6 months old, when I changed them last. #1,2,& 3 looked pretty good #4 & 5 had slight fouling #6 was fouled Any idea on what could possibly cause this? I don't wanna just start changing parts. Are there any test I can run to help determine the cause? I have a picture of the plugs but not sure how to add it to the board. |

Start with your most cost effective options if you feel you need to replace, misfires are usually ignition, it is directly related to fuel and air, so start low (cost) and work your way up as necessary (in terms of cost) even cleaning for a start. Eliminate one by one the possible variables. (a check list so to say)
Ignition Coils, Spark Plugs, etc, examples are Injectors and Fuel pump being on the higher end in terms of cost, decide wisely and we here as a community are here to assist! |
