Help, My instrument cluster randomly went out??
I am new to this so sorry if I make any mistakes. So just yesterday I drove my 2007 e90 BMW 335xi and the instrument cluster was working just fine but now I get in my car to drive it and it doesnt work at all. My OBD II socket works just fine. I need help please, I just bought it.

Hey Cyless welcome!
To clarify what do you mean by "doesn't work at all". Like the gauges don't work or just the displays? Is there no backlight? The more information you can provide with as many specific details as possible will help us point you in the right direction. There are sort of infinite possibilities at this point that could point you to where to even begin looking. Step 1 would be to get a good BMW specific scan tool theres plenty of options out there from commercial tools like sold on Amazon to phone based app tools like bimmergeeks protool or laptop based applications you can download like INPA or ISTA. A BMW specific scan tool might be able to read a code for an electronic fault or loss of communication to a specific module that could cause that issue. If you are new to the BMW life a tool like this will pay for itself many times over and is a great investment for you. For your door issue, each door has a door contact sensor/trigger that is pushed in when the door is closed you could have one that is damanged physically, disconnected or just failed entirely. Look at whatever door is showing as being open and ensure the pin pushes in and out correctly and is detected by the car as "closed" I also found that some models needed to have the FRM reprogrammed due to the same issue but unsure if your car fall under that service bulletin. I would have to research more and well... I'm lazy right now. |

Apparently cluster issues are not that uncommon. Here's a sticky about it in the 'coding' section; not sure it applies here, but just in case it comes back:

Does Outside Temp display remain shown? Time as well? What about Fuel Level? B/C Buttons on Turn Signal Lever? Fuses do NOT normally function intermittently, on/ off/ on, etc. Attached is ISTA ScreenPrint of KOMBI Wiring Diagram with Lines ID showing function of the 7 wires. Note Outside Temp display & B/C buttons are ONLY hard-wired functions. All other inputs are via CAN Bus, K_CAN_H (Orange/Green wire) & K_CAN_L (Green wire). If the K-CAN Bus Inputs are intermittent, then I would check the Connector X11175 on rear of Instrument Cluster, and also Connector X14272 (Black) at the JBE, per the attached Location & Connector View ScreenPrints. Check for any corroded/ damaged Pins/ Sockets, clean & reassemble. These locations and Fuse identification are for LATE 2007 335i, built AFTER 3/1/2007. You want to check Power Supply (pin #9) and Ground (pin #18) as well as K-CAN pins. If you have an EARLY 2007 335i, those items differ, so post back with your Last-7 Characters of VIN. George |

Currently I've unplugged and cleaned the plug for the gauge cluster, checked all fuses related to gauge cluster OBD and looked over the power distribution box and nothing really looks out of place. I will double check all the wiring you have referred too and check back. Just weird to me the radio turns off as well but my build date is a later model 07 so everything you outlined should apply. |

If Radio Display goes out (A/C Control Panel display too?) along with KOMBI functions, that suggests a K-CAN bus issue.
Any loose connection or short to ground in that "bus loop" can cause communication issues between Modules. That could be confirmed by reading Fault Codes in ALL Modules, and if you have multiple modules with "Message Errors" (no message received from 'X' Module) then almost certainly an issue with one of the Orange/Green, or Green wires, or Pin/Socket at one of the connectors. While Fault Codes will NOT precisely identify the location of the fault, they MAY offer some clues. My "layman's concept" of the K-CAN bus is that it is like a computer network, where each Module/Computer sends and receives signals via the "cable" (Orange/Green & Green wires). Any electrical issue that disrupts or scrambles those signals causes abnormal Module behavior. Voltage spikes due to faulty Alternator Voltage Regulator can cause a "Light Show" on the Instrument Cluster, but that is NOT what you are reporting. Your issue sounds MORE like a wiring or connector issue in one of the bus wires. ISTA SSP of K-CAN bus is attached. I would begin with the X14272 connector at the JBE, per earlier Connector View.

Hi, sorry for reviving an old thread but I’ve been have issues too where my cluster is on receiving power with all emergency lights on (no LED Screen or backlighting) and when I flash high beams they brighten but nothing else.
Any help is appreciated |
