Battery voltage 583926492916V HALP!
Hello everyone, made this account because I'm running out of ideas as to what the source of the problem might be.
The car burned out 4 starters so far ( lifetime warranty AutoZone wohoo) It seems to only recharge the battery for startup only, so I'm not able to turn on anything because then there won't be enough juice for it to start. Tested battery ok Car will not start (everything lights up but starter won't crank) if I unlock the car with the handle sensor, I have to unlock the car with the key and it turns on no problem. Official Carly Diagnostics Report 3 (E90), Build Year 2006 categorized as Middle class was diagnosed with Carly on Sep 21 2019 Carly found 22 control units. 19 fault codes were detected.

 My next guess is the alternator voltage control, or the IBS on the negative terminal |

However, you have to understand what each Module does, what it controls, and its circuit diagram (power supply, Inputs & Outputs) to understand the True Importance (or irrelevance) of a particular fault in a particular Module. Does your vehicle have any security system of any type, either factory-installed, or aftermarket? I am NOT familiar with any such system, but it appears that when you lock the vehicle, thereby activating the security system which includes a Start Signal immobilizer (disables CAS Start signal to Starter), CAS is NOT "Enabled" when you unlock vehicle with Remote, but it IS Enabled when you unlock with mechanical key (rotate driver door lock cylinder). Does everything else in the vehicle operate normally when you unlock with Remote Key and enter? Does the Radio come on when you insert Key in Insert Compartment? Do the Windows operate? Does the Instrument Cluster light up when you press START button without foot on Brake? Here is the CAS circuit for your 2006 330xi. Note the Starter Motor Solenoid (M6510a) gets a signal from the CAS to activate the Starter via Pin #22 of the CAS Connector X13376. Note also that the Steering Lock, M137a, ALSO is controlled by the CAS (does your steering remain locked when START button does NOT activate Starter?): https://www.newtis.info/tisv2/a/en/e...system/r14Nexa So even though Carly is giving a "Bogus" Voltage readout, your battery and charging system are probably fine, but your CAS Module is NOT Activating the Starter Solenoid after locking/unlocking using the Remote Key. Test that theory by doing the following: 0) You should probably Lower your Driver Window to do this test, as if the Central Locking System does NOT work properly, you may need to use the mechanical key from outside to unlock driver door.  A) Start Vehicle (after entering WITHOUT using Remote to unlock) & then shutdown engine and restart. Does THAT work OK? B) After successful restart when NO locking of vehicle, Test Central Locking System effect on Start circuit by: lock all doors using Central Locking Button on Dash. Unlock by using that button again, and try to START. Does THAT work OK? C) Test use of Remote Key to Lock/Unlock: remaining seated in vehicle, use Remote Key to Lock, and then to UNLOCK the doors. Try START. WHAT happens? I'm NOT absolutely claiming that any of the above is actually what is happening with your vehicle, but that is the most likely explanation I can think of upon facts provided so far. Please do the tests suggested above & let us know the results. BTW, have YOU ever used Carly before on that vehicle? Do you know how to read the mileage/km when a particular fault code was saved? INPA & ISTA will give that mileage data and also tell you if a particular fault is "Currently Present" or not. That information is essential to wading through 20+ fault codes. My suggestion is to record the fault information NOW displayed by Carly, and then CLEAR all codes and start fresh. NEXT time you read codes, get ALL Freeze Frame Data and Details related to any Code and post here. If Carly CANNOT either do that, or provide documentation that explains HOW to do that, then let us know if you have a Windows Laptop, Android, iPhone, etc. and someone can suggest a Diagnostic Tool/ Software (such as INPA or ISTA) that will actually give useful and intelligible information. BTW2, there is MORE to Diagnostics than Fault Codes. INPA or ISTA will allow you to read Live Data showing voltage at the various "Terminals" which will show you if Terminal 30G is activated (powering many systems); if Terminal 15 (Ignition) is activated when pressing START button; and if Terminal 50 (CAS Starter Activation Function) is active when pressing START with foot on Brake. Challenging issue, please let us know what you find, George Last edited by gbalthrop; 09-22-2019 at 12:48 PM.. |

Maybe you should use and actual voltmeter to make sense of things.

It seems to only recharge the battery for startup only, so I'm not able to turn on anything because then there won't be enough juice for it to start. [Sorry, your charging system does NOT work that way -- your CONCEPT of how the charging system works needs improvement. Suggest reading the attached] Thanks ill give this a read Tested battery ok [WHAT did you test it with? What was the Voltage?]I removed the battery and had it tested/ fully charged at O'reillys, cant remember the voltage at the time i believe it was holding 14V, the guys there told me that it was working perfectly Car will not start (everything lights up but starter won't crank) [THAT is what the A0B4 CAS code confirms] if I unlock the car with the handle sensor, [;] I have to unlock the car with the key and it turns on no problem. [So if you use Remote Key to Unlock the vehicle, the CAS will NOT send signal to the Starter Motor; BUT, if you unlock with the mechanical key (or don't lock car I presume) the START button activates Starter via CAS Module as it should?] I forgot to mention that theres been a few time that the car doesn't go into sleep mode if i don't lock it with the remote. I have not tried just unlocking it with mecanical key and starting it Official Carly Diagnostics Report [you can forget virtually everything Carly tells you with its "Faux Data" -- Carly "buried the lead" 'cuz the CAS module is NOT a simple "Immobilizer" and it is NOT fault-free as your summary suggests. The CAS Module is responsible for unlocking the car, activating other systems, and providing the START signal to the Starter Motor. The A0B4 Fault (A0B4 | CAS: Engine start, starter operation) tells you what is happening. What it does NOT tell you is WHY the CAS is NOT sending a Start Signal to the Starter when START button is pressed -- when you have used the REMOTE to UNLOCK.] This doesn't happen if i unlock the car with the remote first, i am just so used to the door handle sensors unlocking the car when i walk up to it I don't mean to be harsh with you -- it's NOT your fault that CARLY gives so MUCH BS, and apparently so LITTLE Instruction on how to use the Tool and proper diagnostic concepts. I haven't seen ANYONE post on any forum who seems to understand the "Faux Data" that Carly provides. It WILL at least give you the Fault Codes if you know how to wade through all the BS. No worries about being harsh or straight forward, thats what im here for to get someone elses opinion However, you have to understand what each Module does, what it controls, and its circuit diagram (power supply, Inputs & Outputs) to understand the True Importance (or irrelevance) of a particular fault in a particular Module.

Does the Radio come on when you insert Key in Insert Compartment? Do the Windows operate? Does the Instrument Cluster light up when you press START button without foot on Brake? Yes everything else works as it should usually, exept from time to time something weird and random will happen, ( once the windows would not function unless i pressed the window/childlock button on and back off) (one time the sunroof would not close all the way leaving a 10 inch gap wide open ) ( Here is the CAS circuit for your 2006 330xi. Note the Starter Motor Solenoid (M6510a) gets a signal from the CAS to activate the Starter via Pin #22 of the CAS Connector X13376. Note also that the Steering Lock, M137a, ALSO is controlled by the CAS (does your steering remain locked when START button does NOT activate Starter?): The steering only locked the very first time that the problem came up, hasn't happened since https://www.newtis.info/tisv2/a/en/e...system/r14Nexa So even though Carly is giving a "Bogus" Voltage readout, your battery and charging system are probably fine, but your CAS Module is NOT Activating the Starter Solenoid after locking/unlocking using the Remote Key.

Has the CA system been working as it should (other than the START button not activating? If NOT, is it functioning at all -- HOW is it MALfunctioning? Here is the TIS circuit diagram for the CA system Inputs to the CA Control Unit, and that Control Unit provides a signal to the CAS Module via Pin #30 of X13376: https://www.newtis.info/tisv2/a/en/e...access/fyynscY Note that there are separate modules & antennas for each front door, driver & passenger. You might test to see if unlocking using CA has EXACTLY the same results whether you unlock by proximity to driver door or passenger door. If the NO Start issue only occurs when you used CA when approaching locked vehicle, then any of the tests I suggested earlier should NOT cause a NO Start situation, and we know CA is the Fault area. Please let us know what you find, George |

Yes this is my first car I've gotten in debt with and that is one of my favorite features, along with not having to insert the key, since I commute a lot for work, I enjoy walking up to the car, hopping in and pressing start without having to reach for your key (until this started happening) Has the CA system been working as it should (other than the START button not activating? If NOT, is it functioning at all -- HOW is it MALfunctioning? the CA system has been working as it should, except for this one fault, I thought this issue could have been related to the mirror battery deep discharge code,I started troubleshooting this but have not spent much time on the mirrors since the fold in feature does not work (they hyper-extend and I had to cut the white wire coming to the motor in charge of this function so they'd stay in place) I'll be replacing them soon anyways, Here is the TIS circuit diagram for the CA system Inputs to the CA Control Unit, and that Control Unit provides a signal to the CAS Module via Pin #30 of X13376: https://www.newtis.info/tisv2/a/en/e...access/fyynscY Note that there are separate modules & antennas for each front door, driver & passenger.

If the NO Start issue only occurs when you used CA when approaching locked vehicle, then any of the tests I suggested earlier should NOT cause a NO Start situation, and we know CA is the Fault area. leaving the car unlocked for over an hour caused my car to struggle to start, seems like it never went into sleep mode, opened with mechanical key and starter did kick in Please let us know what you find, |

Turns out the battery had been previously replaced by a shop and they did not code it properly.
This in turn damaged the INteligent Battery Sensor, luckily I found a perfect one at a local junk yard and purchased a new battery with a higher CCA since I live in Chicago. No more battery drains since then! Key things to look out for is your battery, alternator or voltage regulator, grounding straps! There are two, and I also found out that by doing the stupid M3 coul filter mod, rain water would go into my engine compartment and drip directly onto my starter which I replaced several times trying to diagnose my issue and every single starter removed was heavily corroded. Good luck! |
