Start Stop button stays on! Battery discharge.
Start Stop button stays on constantly. Have a cc id 415 (battery discharge) code. What would cause the stop start button to stay on? Any experience here?

Have you checked after like 30 minutes after locking? That button, and some more lights around the shifter stay on for much longer than the rest. Might be something else draining the battery.

Sorry not to answer sooner. This seems to be one of those things "Everybody knows", but there is NO Documentation (Bentley, ISTA, etc.) to support that "Common knowledge". I've looked for anything in those references related to START/Stop button remaining lighted, and have NOT found anything (yet ;-). So here's MY Concept, based upon reading posts by others, and checking my own (properly-operating) 3/2007 328xi: The Light of the START button goes OUT (along with LED indicating Park Position on the AT Shift Lever), when the vehicle enters "Sleep Mode". That SHOULD occur ~ 15 to 30 minutes (depending upon whether vehicle locked or NOT), after remote key is removed from insert compartment and door is closed. "Quiescent Current" or "Parasitic Draw" occurs when a Module which powers (or controls relay powering) a particular electrical consumer does NOT go to sleep, OR the Module CANNOT go to sleep if there is draw by such a consumer line when NONE should exist. I do NOT have a comprehensive list of things that can prevent vehicle from entering Sleep Mode. However, based upon the PORTION of your Diagnostic Scan you have attached, the FIRST thing I would check is WHY you have communication (Bus) or Message errors, and several Modules (FZD & perhaps EKPS) which Tool reports: "No response from ECU: No response". Similar reports appear for LMV, NAV & PDC. Since it appears that the Door Contacts are involved in Sleep/Wakeup, and you have FRM Fault Codes for Door Contacts, diagnosing and fixing that issue MAY resolve your "Never Sleep" issue: 9CBC | FRM: short circuit at front door contacts | frm_70 | Driver's side footwell module 9CBD | FRM: short circuit at rear door contacts | frm_70 | Driver's side footwell module If your vehicle in question does NOT have such modules, then those are NOT error messages. BTW, it's ALWAYS helpful to specify WHAT the Brand/Model of Scan Tool used may be. I'm used to INPA/ISTA which provide LIST of all Modules in the Vehicle, and/or communication status of each. Your KOMBI (Instrument Cluster) code, "A3BD" has following definition: A3BD | Message error (junction box, 0x0C0), receiver instrument panel, transmitter JBE | komb87 | Instrument cluster That means the KOMBI Module did NOT receive an expected Message (via Bus system) from the JBE Module. Your FRM codes suggest you may have an issue with rear turn signals or door contacts. Do your Turn Indicator Bulbs light on either side in rear when turn signals operated with Ignition ON? Do "Open Door" warning lights appear when any door is opened, but NOT always on? If you would provide list/ photo of ALL Fault Codes in ALL Modules, make & model of your scan tool, that would be helpful. Also, please read any documentation for your Scan Tool/ Diagnostic App, and determine whether it can display either Freeze Frame Data related to a particular fault, or Live Data. Then let us know what you find. Also, check tool/app Documentation and see how/if it can display a list of ALL ECU's (Electronic Control Units) or Modules in your vehicle, and HOW/IF it can tell you if any Module physically installed is NOT communicating with the Hub (JBE) or your Tool properly. Please provide LAST-7 Characters of VIN so we can provide correct ISTA wiring. George |

In my case this was a draw from the instrument cluster confirmed by pulling out a specific fuse, which enabled car to go to sleep.
The fix was to replace instrument cluster in my case

Good luck I hope it turns out to be a simple thing and does not cost you a kidney and an arm.

Update. On Thursday I replaced the 7.5 fuses numbers 66 and 62, cleared codes and drove about 30 minutes. Then ccid 415 returned later in the day. Friday morning I moved the car in the driveway as we took the X3 on a two day trip. I expected to return to have the same problem, but it's gone. Did the module finally put itself to sleep while I was gone, was it the fuses or the long drive? I don't know. I suspect the culprit is the FRM module, but maybe it righted itself. I will keep you updated.

If the car sits outside a lot, the "Door Contacts" (in the latch I believe), or the Connectors in the door, or at the door hinge may be causing the issue, rather than the FRM itself. That would be particularly true if there are NO Lighting issues. The Door Contacts are connected to the FRM Module, and INPA/ISTA can test them for proper operation, WITHOUT disassembling anything. Just 5 minutes to connect computer and open correct INPA Screen, open & close each door. My understanding is that the "Door Contacts" are in the latch on each door. Simply "Exercising" the latch by opening and closing EACH door 3 or 4 times MAY restore proper contact operation. Of course that is just ONE possible cause of your CC-ID 415 and battery discharge. Unfortunately, most Shops are good at R&R (Remove & Replace). DIAGNOSIS: NOT so much! This MAY be one of those cases where taking an hour or two to install INPA and learn the basics, and investing $50 in a K+DCAN Cable is the BEST way to solve the issue. If you have another BMW, that makes that approach TWICE as advisable. George |

Well, we have noticed something. It appears when I don't wash the car for a few days the problem disappears. Could it be that water is creating these codes?
9CBC | FRM: short circuit at front door contacts | frm_70 | Driver's side footwell module 9CBD | FRM: short circuit at rear door contacts | frm_70 | Driver's side footwell module" |

Have you checked to see that the DRAIN HOLES in the bottom of doors are NOT plugged? If you shake the open door after washing, do you hear water "sloshing" inside? Are the seals at base of window glass in good shape? Do you REALLY wash your car every day? LOTS of new parts thrown when water, corrosion, etc. issues are easily fixed. The PROBLEM is Diagnosis & ANALysis. George |

I'm assuming you don't have any door open warnings when the doors are actually closed? It appears there was a SIB about a problem like this, but it would usually cause those door open warnings: https://www.e90post.com/forums/showthread.php?t=1587346
It does appear to be related to moisture/humidity - the FRM seems to read the contacts incorrectly if there's moisture in the area. Checking the doors and/or the FRM for any signs of water is probably a good place to start. |
