BMW No Crank No Start After Battery Replacement

[@mlmov3417]

Thank you for your service. I had so many problem related to this issue. I have finally found your video, did all the troubleshooting, replace the battery, register the battery, reset the ELV and CAS counter, after 3wks the problem came back. So now I think I have isolated to the battery sensor. So many hours wasted on this car troubleshooting and the inconvenience car not working in the middle of nowhere. This video was a Gems!!!! Thank you...

[@DTEAuto]

Glad it helped !

Hello Sadel, I have to say you and your presentation are remarkable. I replaced the battery in my wife’s 2006 BMW 530 XI. I thought I took all precautions but I was wrong. I must have shorted out the battery sensor. I put a new battery in, and nothing happened with the starting circuit only messages that nothing else was working. Thank God, that when I looked on KZbin, I decided to watch your video. You are very clear, concise and patient while speaking in a manner that we can all understand. I did exactly what you said by unhooking the connector to the starting sensor. I inserted the key into the ignition heard the steering operate and when I push the start button, the car started immediately. I can’t praise you or thank you enough for all your efforts, and I will certainly follow any and all of your videos. I highly suggest anybody with an issue look up DTE engineering and watch Sadel’s 0:48 videos. Thank you again so much!!

Thank you Sadel. That's exactly how i like to diagnose & share with others using a lab scope and checking signals with the connector connector & disconnected to see who is supplying voltage and that way we know the voltages with a known good waveform. That's how i do it & i take notes on every car. As you know most manufacturers don't give us enough information on waveforms neither voltages. Thanks for sharing.

Hello Sadel, Your explanation of how the CAS works, along with the wake-up signal, was excellent. Thank you for sharing the details of the system with us. A++ once again.

As your pulling out the brown wire out of the IBS, what SHALL cause harms to BMW?? Or IT means only that the CAS MODULE is always waken up even locking??

[@reagancampher2421]

Hi Sadel your video just saved me so much money i would like to know where did retrieve the schematics on the bmw as depicted in your video

[@DTEAuto]

glad to hear that, and it's from a paid service online, there's a few that offer them (Alldata, Identifix, Mitchell, etc)

My car Bmw x5 e70 has problem : sometimes it occurs the case: the Ignition On is still ok ..but the car does not start.. If i try more times try to start, the key signs stuck /hard to ignition On or Off, adding some clicking sound coming from in the fuse box area, behind the glove box, and adding My tail lights will not turn off when the key is out of the ignition..(the tail lights seemed to have finally gone out after being on for quite a long time) But whenever at that times, if i take the CAS out of the car and unplug the wires for a while and I plug again in the wire jack of the CAS box, the car starts immediately as normal lịke "RECALL/WAKE UP the CAS"... for long long months.. but afraid that like used to, it maybe shall occurs like above in the future... As your video , May i ask ? The CAS is not bad/lose programming . Cause I change the new batterry (VISTA) without register? It damages to the battery sensor on the negative cable and it shorts out the wake up signal and prevents it from starting at all.rite??? So, whenever it occurs, i shall pull out and plug again the Cas plug to reset the CAS counter ?? Or should I do as your video??

Thank you so much i have this same model car an this video is a jewel.i needed this video just incase

Can y show me how to test as your video reading Voltage when ignition On/and off?

[@clueless6559]

So the ibs is not required for starting but is on the wake up circuit for ews and powertrain etc , wonder if the battery was changed for this faulty ibs ? when i saw the esl code i went for that too , great video and follow up diag with the scope , that sort of information is often overlooked , thanks again.

[@DTEAuto]

Correct, it's not required for starting but in this case took down the wake-up circuit which affected the ews/cas. Thank you for watching and glad you enjoyed!

[@Greasedagod]

Hey sadel, I just did the valve cover gasket on my 2010 bmw 535i xdrive myself at home and the car doesn’t start or crank for that matter, I made sure I did everything correctly well at least I thought I did, I’m guessing I was wrong .. hopefully you could help me

[@martingregory5955]

The thing that springs to mind is the battery was changed, why? Probably flat so would have been charged or jumped. The best way to fry the IBS is to either direct from the battery like normal cars. You can't do that as have to do either from remote contacts under the bonnet

[@princenyc9271]

I have a bmw 645ci that had a starter issue a few mths ago i replaced it and the car started up fine. the car is a project so its been sitting. i tried to start it up yesterday and it doesn't turn over no clicking from the starter. the ivm and battery was replaced also. just tried what you did in the vid and no luck everything else works on the dash and diamond key. im stumped

[@DTEAuto]

you would need to have the ability to do a complete system scan to get an idea of what codes are logged for a sense of direction.

Many thanks ... my BMW 1 series petrol 2005 model has the same fault. . The fault is intermittent where all the relays and solenoids all jump ... but when pressing "START" button ???........NOTHING . Mine is RHD and if i wiggle the wires around the OBD2 it starts and i'm "good to go" . I bought the car cheap as i was desperate but i think this is why ? . For one of the best car makers ever why make a back circuit ... for a back up circuit... for a up circuit... for a back up circuit ??? / WHEN I WONT START ANYWAY LOL . Many Thanks

One key starts the car but doesn't activate the door locks, my other one doesn't start but do activate the door lock. What gives?

[@automajstorijediy]

my 2006 bmw e87 120d wont start ewery time i replace battery or disconnect it. its the same with ibs wire conneced or disconnected. so a guy with diagnostic must set something to make car working again. as i remember its always something with CAS module problem. and maybe something else too. why is this happening ? and what is cheappest diagnostic tool i can buy ,to doo it myself next time ?

[@donkeyhog4321]

I had the same issue. For ( quick fix or emergency ) disconnect the negative terminal from the battery (Very Important) before you proceed the next step., then short the circuit from the front hood. There is a positive terminal that connect to the battery. used a wire clip connect to positive and touch the engine block for few second. This should reset all electronic. After that remove the wire clip. Reconnect the battery negative terminal. Voila your car should start. Remember this is a temporally fixed. The underlining issue is still there. Once you stop the engine. You will have the same issue. To rectify the issue, replace with a new same model factory battery. ie: Model H8 AGM . And register the battery and Reset the CAS counter for ELV and Cas. This should fixed the issue. For the Battery Registration and CAS counter reset. I was using the software tool 32. for window 7. But is a easy software android apps. MHD N54 download apps on your android phone. used the MHD bluetooth adaptor or K+DCAN car diagnostic tool cable OBD usb cable. The MHD N54 is very easy to used provided you are replacing the same battery. Otherwise, if you have a different battery, then it require coding the new battery. Hope this help! Good Luck!

[@curtlandgraff5380]

What does this cost to fix this?

[@DTEAuto]

would consist of diagnostic time cost and then the cost of the new negative battery cable with sensor on it and the labor

[@ahmetisler1829]

Thanks

[@ronaldbrooks5427]

Is that sensor on a BMW c 231i

[@DTEAuto]

most likely yes

[@ApexKilla49_]

This just happened to a customers car. Car sat for a while he drove it over to me, the battery died, when i went to give it a jump. Now it just cranks with no start. Smh

[@colebraman597]

BMW stealership quoted my brother $4500 for CAS module replacement after les Schwab replaced his battery. Do you think this is legit?

[@DTEAuto]

There are options when dealing with module replacement on these, including CAS module, where you don't have to use the dealership and get new from them. Like some of my videos, the option could be to get a used unit and program it to your brothers car via special tooling.

[@colebraman597]

When changing battery on newer models maybe 06 and newer. You have to program the battery, then this wont happen.

[@DTEAuto]

Registering the battery doesn't have an affect on if the ibs is shorted

[@stretch5832]

So this video is for what? 🤔

[@DTEAuto]

to show what can happen after a battery replacement if not done with care can damage the battery sensor on the negative cable and it shorts out the wake up signal and prevents it from starting at all.
