Out of topic question, i got a e60 3.0d 218bhp did a egr and dpf delete + stage 1. At the moment i got a maf and map sensor error and increases emission message. My question is, the map sensor should it be replaced with a higher boost one as in to read 3-4 bars or just the stock one would do? Or should i try one out of 535d?
Hi , very good videos , lots of info new to ownership of e60 , I’m getting taillight failure come up even tho all brake lights work, also what’s thoughts on auto box on 520d 06 is there a filter to replace got malfunction fault once ? Any help would be appreciated! Thanks
Hi Dean, I have been watching almost all your YT videos regarding e60 and you really helped me alot with other issues now fixed, now I am stuck with a CAS error A0C0 terminal 15 output 3 ... my car is a BMW E60 520i M54B22 2003. The car cranks but no start and also get the Ignition Faulty on screen and a red car on stand with diamond key in position 2. I changed the battery, ibs ,ignition switch wire harness to cas (14pin) the transponder. Key is ok checked with Inpa. With Ista i get the same a0c0 cas error but no other issue. I did checked all fuses in rear fuse box, glove box. Changed terminal 30 relay, the green relay in globe box. Checked voltage on battery ok, front under bonnet ok, grounds are ok, starter connections are ok. Looking at your videos for this type of issue i am stuck at why the car shows ignition faulty on terminal 15 output 3 Value above threshold and no voltages or amps to be able use a voltmeter. I pulled out as much information as i could from ista+. If you are aware of this type of issue please help with advice. Regards.
He I have problem with my bmw e61 530xd 08 No power to left side headlight,rearlight And got this terminal 30B with no power. What is needed to be replaced?
Truly one of the most experienced BMW experts I’ve ever seen if not the most, and I’ve seen a lot trust me, never useless videos nor useless infos, wondering how u still haven’t been hunted by one of the giant corporations man, Many of BMW owners went or going through hell from dropping their cars over and over from dealership to another just to know what’s wrong with their cars and what’s causing but no luck, while u my friend lying it all out, the cause, the diagnose, solutions, and in a very straight forward style... thanks a lot It’s highly appreciated, wanted to tell you this in a while before asking any question or anything, it’s is very nice of u, thanks a lot and God bless
Being American in America I realize more and more Europeans understand BMW 1000X better than we do here smh. Fixed starter, alternator, and starter when it was something this simple 🤦🏿♂️ you definitely have a new subscriber boss!
I came out to my car a few months ago and it was DEAD. its a 2014 550i. someone was looking at me and said the headlights had been on and flashing. alsoihear some clicking in my glove and trunk. I didnt know what the hell was going on, it was like the devil was controlling my car...lol. I pulled a relay out or the glove that was clicking, and again in the trunk. I measured the battery it was doun to 9.9v. after looking into it i found out about terminal 15, 30 and there was one other. i love learning about my car, Im mexican and i love learning about my german babe!! This guy is awesome, look at his videos before your car breaks down so you know what's going on with it.
The IBS Battery sensor is there for the stop/start system to ensure there is enough power in battery to restart the car. It reads the battery health. By disconnecting this sensor stop/start does not function, it effects nothing other that stop/start and variable charging. When the sensor fails the car may not start, if it does the battery charge rate reverts from variable to a standard charge of around 14 volts and the stop/start system seises to work, that`s it. I removed that sensor on my Porsche Cayman 3 years ago and my Audi TT mk3 12 months ago with no issues. I do not like stop/start.
The key doesn't wake up the car if you don't touch the door handles. If you don't have CA there is not even a physical way for the car to activate the key, if you do have CA you need to touch the door handle to activate the key (and hence start the fuel pump priming) What does wake up the car is pressing the key, opening the door, touching the door handle (if you have CA), or even moving the car 1 cm. But if they key is stationary inside the car or next to the car, even if you have CA, it won't wake up the car (unless there is a different problem with the car). We always have many cars in our showroom with the key inside. They don't wake up until you touch them. Priming the fuel pump is not a check, it actually makes sure the car starts quickly. I do still agree that it's a very bad idea to remove the relays.
Interesting stuff. Just replaced the entire rear power distribution unit on my e61 today as it had been soaked by sunroof leak under previous owner and was heavily corroded. This solved a few electric problems I was having, but still left with 2 annoying ones: 1) heated rear window is ALWAYS on even when ign is off 2) car will not wake up using remote key fob but will on key in lock. Once unlocked and awake remote fob works as expected Both issues doing my head in. Was interested to see that red wire bridging 2 looms in your video. I have the same and assumed it wasn’t factory
Brother, you are amazing in your expertise. The information you are providing in this video answers what I have been researching and asking for a long time. Thank you!!!
I have a 2012 750 xDrive that sometimes throws errors on ignition start related to ABS, Parking Brake, and Traction Control. Othertimes it will show DriveTrain Malfunction. If I crank in a certain sequence it does not have the problem. I have to Power the car off, driver door as if exiting the vehicle, close the driver door, and then wait for the dash lights to go out on their own based on the timer setting. It is usually 30 seconds. I was looking for a faulty ground wire, but I am going to check your relay suggestion as well. Very good video. Thank you! --Matt
Hi great video very well explained, I have seen terminal 15 reset on my wurth diagnostic tablet when plugged into a 2012 520d, I've got no front or side left indicators and both halos not working and a long list of fault codes, can you recommend anyone who will test the frm? Is it possible to fit standard lights (not the expensive hella afl xenon) and be able to have lights without any coding needed?
I just ran across your video when I was trying to fix my dead drivers side window. Car was at dealers for new radiator. It took them 30 days to replace and when I got car back(e39 m5), the time and date had to be reset. I’m guessing that they disconnected my battery while it sat there and that has caused the window problem. When I plug in a generic diagnostic tool it says that terminal 30 is off and also that fuse1 on the GM is off. Except for the drivers side window, everything else works perfectly, each individual window works using its own door switch and also using the drivers master switch. Only the drivers window doesn’t operate and I need a logical place to begin.
I have been receiving the a559 fault for a long time and my battery is quite dead. I changed it 2 years ago and it shows me 61 and 54ah, it doesn't charge more than 49 or 50 percent. Could it be that they are poor quality batteries or a problem with the ibs? xo.or detect it?? Thank you
Dammit my friend!! If I could bet on one thing today on this 08' 328i ive got from my customer is that any person who knows that they think they know ,, well its just that, think ya know" ....LISTEN TO THIS MAN EVERYBODY CAUSE HE ISNT BLOWIN SMOKE. Any problem before you even go tearing into these rides , watch and listen to the words that come out of a pros mouth.. he just saved again for the 30th time , my time, customers being without their cars and got me on to the next customer.. Thanks again B est M echanic W orldwide... 😁🤘👍
Thanks very much for sharing all that information and trust me I believe you and I honestly don’t know why anyone with a brain in their head wouldn’t believe all what you have told us either. This type of video gives everyone who is paying attention to what is being said a valuable education and if they are a owner of such BMW are also saving them a lot of money for the whole time they own the car. Even if you don’t own a BMW there is still plenty of valuable information to be gained from this video so I for one am most grateful for your time and effort in making this video and sharing your knowledge. I hope that your channel has all the success you deserve. Peace out ✌🏽
Hi @BMWDoctor, First I’d like to thank you for this Vid. Lots of infos that you just don’t find like that on the Web. This year I had some bad luck with a BMW F07 my battery drained out of power over the winter and on March while trying to jump it with a friends car the cables where connected on the wrong poles. Battery side. Now the nice car doesn’t do anything at all. Completely dead. Where would you advise to start checking to at least be able to unlock the doors. Right now only accessible on the drivers side with the key but all the electronics are dead. Already checked that Relais (30) you mentioned on the Vid. Any ideas where the troubleshooting should go on?
Great video! G12 bmw. Front end smash airbags deployed. Now power to the tailgate and unable to open boot. Anyway of opening the tailgate from front fuse boxes?
Thanks for making this video. I've got codes for 2DC3 and 2E8D that I've been putting off. You mentioned the clock resetting and mines been doing that along with the car not always unlocking when I grab the door handle.
Was changing blower motor on 2012 650. Didn’t disconnect battery and contacted the positive to metal where the electrical housing is above blower motor. Everything else works but car won’t start. Wants to turn over but doesn’t. Loaded question but what do you suspect blew?
Terminal 15 is hard wired / soldered to the board ? Is it meant to be removed .. mine doesn't seem to want to come off. I've got no crank , all my lights and battery are fine.
Same question....and a second part to this, is there a "good" way to jumper the distribution to simulate that relay coming ON to test? I have no terminal 15 voltage...
Is there a similar distribution box on the F10? Could that main relay affect my valvetronic actuator? I don't want to pull the top off the engine if this may be part of my issue with the drivetrain malfunction.
Hey doc, firstly, thanks for sharing your knowledge, much appreciated, for I'm a first time bmw owner. So my 2008 528i started draining my battery, my scanner showed ibs sensor defective. I replaced the ibs sensor, bought a new battery cause existing battery was 5 years old, and when I go to register the battery, the scanner says to turn on terminal 15. Btw, I'm using launch creader V2. Is it safe to say that relay for terminal 15 is faulty? If so, do I just disconnect the battery and replace relay for terminal 15? I know how to check relays but my concern is that I do it using proper procedure. Please help.
He mate I did a manifold clean of soot out on my BMW 520d f10 and forgot to unto the battery now the car won't start after putting it together any help will be much appreciated sir.
Hello is that the audio wiring with all the different colors wrapped up in the black tape? I'm trying to tap into a speaker wire to run a low input rca box? Thanks

My car's battery is often weak even though it has been replaced with a new one, so I often unplug that relay every time I leave the car for a few days to avoid battery deterioration. However, I don't know what the consequences of removing this relay will be?
Would you have a fuse map for a 320d 2008? I’m having an issue with the electric windows on driver side and both keys stopped locking/ unlocking the car. Any is the maps I’ve looked at appear to not match my fuse board. Thanks in advance
Driving to work today the dash light up everything for a few seconds then back to normal, after in the car park I was backing happened again, check error code and this came out 4C18 I believe is terminal 15, should I go ahead and replace it ??? Thanks in advance
I have two codes CAS (Car Access System - CAS/FEM/BDC) DTC( 1) Count 930751 Abnormal 1 Output, Terminal 15: Short Circuit To Positive and ECM (Engine Control Module - DME/DDE) DTC( 1) Count 1B5101 Abnormal 1 Terminal 15_3, Line From CAS, Electrical: Sho rt Circuit To B+ Could this be related to relay? Sometimes there is a slight vibration that feels like misfire. Thank you for any and all help.
I have a similar problem with a 2005 X3. 3.0. If it sits for a few days or more there is no power anywhere. When I hook up jumper cables under the hood still no power. I have jump it directly at the battery. Then I’ll g get lights on the dash. Where should I look. Is this video the same for the x3 ? Thank you from Phoenix Arizona.
I have a m57 e61 2005. Crank no start. Car was on parning lot for few mounths and battery dead. Charged the battery and car crank but not start. What happend? Car worked fine when parked it.
Hello I’m having a random no start no crank issues with my 135 2008 n54 The car drives great with no faults And till now,happened 3 times ,it won’t turn on. I leave it for 30 minutes, and it’s fires directly. No codes,,battery new,starter changed 2 weeks ago ( had a code on scanner so i changed it) I Tested the grounds,,,all fine. Any idea what to check?
Hi BMW Dr,. Today after I started the car, my wiper started moving , central lock and trunk, backup camera all malfunction. I noticed that when its a hot sunny day, it goes crazy. When I scanned the car, I got this error "Code 8021D3 Terminal 30F: no reset / shutdown due to error in terminal 30B input" Does it mean I need to replace the RELAY ? After 1 hr , the car went back to normal. What do you think the problem is ? My car is a 2011 F10 535i
Hi just quick question I have bmw f10 and after diagnostic scan come out with terminal 30 relay under voltage is that mean I need to replace the terminal 30 relay ? If yes should I disconnect battery before replacing this relay ? Many thanks for your response.
So the relay 30 will cause no power at all to the cabin??? I have nothing at all. No dash no lights no nothing. The alarm wants to keep sounding too. Car was fine yesterday!
I there I have been looking at your videos great stuff I have just bought a f40 128 ti and because I work away all week when I come home the battery doesn’t turn over very good can I put a solar panel tricycle charger on the jump connection under the bonnet I used to use this on my Golf GTI and had no problems hope you can help mike
Hi Dean, do you have any experience with the error retrieved from ISTA code 000090 IKE: Voltage supply, terminal 15, faulty or INPA code 144 Terminal 15 open circuit ECU: IKI. Vehicle: 04/99 BMW e39 m5, Symptoms: when engine is at operating temp longer than usual cranking required to start the car, but if you turn key to pos "0" and try again all is ok Thanks in Advance
DO YOU KNOW WHERE THE TERMINAL 30G-F IS ON E90, 2006 E325i, I have A731 code and 2DED code. My radio stoped working as well. The car starts and runs well, but these codes persists and there is a slow drain on the battery, therefore is A731 code. But where is the FN terminal 30G-F?
Hi doc, my 2005 BMW e90 320i cranks but no start. I have checked the fuse and relays still no start. What I have notice is there's no power going to the coil's no spark going to spark plugs. Can help with information to fix this problem
I get intermittent no crank no start issues. Change/charge battery will be mint for a week then intermittently do it again no rhyme or reason to when it does it. Sometimes if it no crank no start leave it for 10 Minutes and off it goes. Do you have any idea what this would be would it possibly be one of the issues. I get a cas code for starter no start.
I have a 2007 550i V8 that after trying to jump start it (yes properly) I got a crank no start. Checked all fuses, have good fuel pressure and getting spark. It appears my injectors are not activating. Changed the Crankshaft Position Sensor and had my DME tested. Still crank no start. Could these relays be the problem?
Hey doc,i got a 2005 bmw 525i 5 series and i got a code AOB2 supply, terminal 30E/30L Can't find nothing on the web for this code, do you have any idea??
@BMW Doctor I have BMW E66 730D 2006 No crank no start, was working fan know when I push the start stop button nothing doesn't turn starter motor, lots of electrical faults on the dashboard, call Sos, safety system! , PDC faulty, go audible charm when I put the key in the dashboard, when I press it it says preheating with a coil logo, then I hear audible clicking from the DDE under bonnet pass side. Also my radio won't show stations to tune in, no TV in back on etc, car battery fully recharged still same. Do I have these fuses and relays as shown on your video in my version of my car E66 and would this cause these faults? Ps car still locks and unlocks with the key fob, I was beginning to think the DDE or ECU has packed up or started motor failed, but with everything else electrical not powering on like the radio I thought it must be something else. Please advise if these relays and fuses would cause my symptoms, and please where are they located on my model
What would cause the vehicle to crank but not start So I replaced the battery in my 08 528xi and then went to start the next day and it was running rough and went to limp mod now it will just crank and won’t start
I've got a 2007 bmw 525i e60 and I've got traction and handbrake light on but handbrake light goes red when handbrake is on. Also have abs light come on when hit 15kph do u have any idea what it could be
I swapped my fuse box due to terminal 15 failing whenever it got over 85F, now the new one has no signal to DME but everything else is great. Would you have any suggestions? IF i paid you would you walk me through it remotely?
Where are these relays found on the e90's? I've seen the relay 30 in the glove compartment, but I don't think I know where the terminal 15 and those 100amp fuses are.
Can i get a part number for the terminal 30 relay please, my 2009 535xi doesnt even have one installed. I was away from my car for 2 years and a bunch of things are fuvked
E90 2005. Auto trans runs fine on smoth road, but once hit road bumps or hard accelerate gearbox start to fail.. Even on park just heavily acceleration makes P icon on dash blink. Where should I look for problem? I think it should be electrical fault? Maybe some demaged wires or plugs? Please help.
Do you know which fuse will cause my interior lights to stay on. For ex my lights turn off and the cluster and I drive but the lights for the shifter and AC and heat are still on all night.
I got a question, I got bmw 328i f30 2012 and I’m having trouble of finding out what’s making my car not start. I got a scan tool that show these store code from FEM which are 8040B9 : De-activtion of terminal 30B: Top startability limit reached. 8040BD : Reset or deactivation of terminal 30F. 0300A0 : front passenger door power window regulator. System not normalised. AND DME 102A01 : Air mass flow sensor, signal electrical fault, 135808 : Valvetronic servomotor, position sensors, electrical: malfunction. Could these Intel help me indicated the effects my car from not starting? Im trying to understand where could these link too. I was told to use a insta+ but idk if it can work on a HP computer. And also told to restart the battery through a scan tool? . Cause I took off the negative thermal for safety for changing a sensor and I was told the car goes on save mode and I have to restart it? But it’s getting power. I bought another battery too cause the old one I had was bad. but It seems fine. I get in several times and it tells me the car battery low. But has a crank but won’t start. I just hope it’s not the timing chain or something else. I’m no tech nor mechanic but I’m doin my research to see the problem.
Do you know about f31 its like most of the its ok but know it would.t start for 2 weeks now first it taps the starter but it didnt turn over. Know even of i charge the batt or NOT. It does NOT make a diff but i change the batt maby it whas No good... Anyways u get too the CAR SIT down the Lock comes off i push start it says preheat.. And then nothing or it taps the starter...
Hi Dean, I have an E70 which is having the following issue, CRANK BUT NO START, NO POWER, WAKE-UP LINE (acc) ON CAS MODULE with 0.13V all time. Already replaced junction box JBE and FRM modules, also starter. What do you think the problem may be? I'm desperate
Hey nellely, do you have a multimeter? If you're getting it to do a good crank (typical crank usually enough to start.) the first thing you want to do it check the ignition fuses, and fuel pump fuse/relay. Also check if you are getting power to your fuel injectors, a NC fieldsense multimeter is fastest and great for this, but if you're just fixing your own car and don't tinker with electronics much, I'd save the hundred (s) and go without. Let me know if you've tried what I said to no avail, and I can walk you through some more troubleshooting procedures. I highly recommend buying a blue driver obd2 reader. They're worth every penny, made in Canada i believe,and constantly getting updates. it doesnt use glitchy, ripped 🇨🇳 code, and is perfect for the average vehicle owner/all the way up to a seasoned journeyman mechanic when they don't want to bust out the giant snapon /autel scantool
hello can i ask have you had this relay cause canbus issues i am testing one at the moment and the faults keep moving around the car ,abs ,then it clear's up terminal 15 and 30 faults then after checking connections , ok, then i had canbus faults on other modules ,intermittent faults .
Hi mate i have an ibs problem(ibs not recognized by the dme ,ibs supply voltage circuit open.Bsd interface between dme and ibs circuit open or loose contact)Made me change alternator,ibs cable etc etc.What could be the problem?
My Car does not open or close when i Push the key Buttons. After a ride it sometimes works again . Like normal . Then after 30 min of sitting it stops working. What can this be . The key is good . Diversity antenna is good . The fuses are good .
Thanks for that bro. My 2008 135i has that no crank no want to go thing happening to it and every time l go to start it l get this buzzing sound coming from around the fuse box some where. What's going on there bro?
On bmw e60 and e90 same thing? i have same problem on e90 2005.. 2.0d. 120kw. no start.. no crank.. faul code a111. changed elv, ibs, battery,, i have emuliator but nothing helps..
When ISTA+ says " carry out a terminal change" does it concern unplug and plug one of these ? I'm trying to service function my new valvetronic (n55) but it fails everytime..
Hello Doc.Can you please let me know the location of cooling fan relay, on a 2010 e60 528i xdrive according to BMW dealership Its in the trunk but it's not there or neither in the glove box or neither inside fender box. can you please let me know if you have the knowledge.Thank you.
My car is giving me this error? It says FRM: Terminal 30A connection, power window faulty though. but I have abs, traction, and brake light on even though I fixed all my abs sensors and tested my passenger headlight with my other and it doesn't work even though the driver one works. any tips? I have the codes if you have time I know you're busy..
I have a 2007 530i no crank no start only now replaced starter and car delays like 5/10 secs turning n turning till it finally catches whatever it's catching to turn over all the way and start but what's causing this I'm clueless and mechanics say all diff things

I'm currently battling a bad IBS and battery on an 2017 F15 X5 with 60k mi. The car died, was towed to dealership they found little to none, died again, boosted several times, died again. After an CEL came I scanned it and it gave me a code for a bad IBS. The car battery won't charge on a DEFA charger (the bad IBS fully depleted the battery 4 times or more). Will be replacing the battery and IBS in one motion, the register it, reset the DME and clear the codes. If this doesn't cut it then I have no idea what to do next...

The terminal 15 on e92 it's not located in the trunk. At least on the UK version. Where can I find him? There's no crank
Thanks a lot
Out of topic question, i got a e60 3.0d 218bhp did a egr and dpf delete + stage 1. At the moment i got a maf and map sensor error and increases emission message. My question is, the map sensor should it be replaced with a higher boost one as in to read 3-4 bars or just the stock one would do? Or should i try one out of 535d?
Hi , very good videos , lots of info new to ownership of e60 , I’m getting taillight failure come up even tho all brake lights work, also what’s thoughts on auto box on 520d 06 is there a filter to replace got malfunction fault once ? Any help would be appreciated! Thanks
Hi Dean, I have been watching almost all your YT videos regarding e60 and you really helped me alot with other issues now fixed, now I am stuck with a CAS error A0C0 terminal 15 output 3 ... my car is a BMW E60 520i M54B22 2003. The car cranks but no start and also get the Ignition Faulty on screen and a red car on stand with diamond key in position 2. I changed the battery, ibs ,ignition switch wire harness to cas (14pin) the transponder. Key is ok checked with Inpa. With Ista i get the same a0c0 cas error but no other issue. I did checked all fuses in rear fuse box, glove box. Changed terminal 30 relay, the green relay in globe box. Checked voltage on battery ok, front under bonnet ok, grounds are ok, starter connections are ok. Looking at your videos for this type of issue i am stuck at why the car shows ignition faulty on terminal 15 output 3 Value above threshold and no voltages or amps to be able use a voltmeter. I pulled out as much information as i could from ista+. If you are aware of this type of issue please help with advice. Regards.
He I have problem with my bmw e61 530xd 08

Being American in America I realize more and more Europeans understand BMW 1000X better than we do here smh. Fixed starter, alternator, and starter when it was something this simple 🤦🏿♂️ you definitely have a new subscriber boss!
I came out to my car a few months ago and it was DEAD. its a 2014 550i. someone was looking at me and said the headlights had been on and flashing. alsoihear some clicking in my glove and trunk. I didnt know what the hell was going on, it was like the devil was controlling my car...lol. I pulled a relay out or the glove that was clicking, and again in the trunk. I measured the battery it was doun to 9.9v. after looking into it i found out about terminal 15, 30 and there was one other. i love learning about my car, Im mexican and i love learning about my german babe!!
This guy is awesome, look at his videos before your car breaks down so you know what's going on with it.
It's always good to see your YT BMW videos. Hopefully my Z4 roadster is not suffering IBS - Irritable Bowel Syndrome. Another 👍🏻s up
The IBS Battery sensor is there for the stop/start system to ensure there is enough power in battery to restart the car. It reads the battery health. By disconnecting this sensor stop/start does not function, it effects nothing other that stop/start and variable charging. When the sensor fails the car may not start, if it does the battery charge rate reverts from variable to a standard charge of around 14 volts and the stop/start system seises to work, that`s it. I removed that sensor on my Porsche Cayman 3 years ago and my Audi TT mk3 12 months ago with no issues. I do not like stop/start.
The key doesn't wake up the car if you don't touch the door handles. If you don't have CA there is not even a physical way for the car to activate the key, if you do have CA you need to touch the door handle to activate the key (and hence start the fuel pump priming)
What does wake up the car is pressing the key, opening the door, touching the door handle (if you have CA), or even moving the car 1 cm. But if they key is stationary inside the car or next to the car, even if you have CA, it won't wake up the car (unless there is a different problem with the car).
We always have many cars in our showroom with the key inside. They don't wake up until you touch them.
Priming the fuel pump is not a check, it actually makes sure the car starts quickly.
I do still agree that it's a very bad idea to remove the relays.
Interesting stuff. Just replaced the entire rear power distribution unit on my e61 today as it had been soaked by sunroof leak under previous owner and was heavily corroded. This solved a few electric problems I was having, but still left with 2 annoying ones:
1) heated rear window is ALWAYS on even when ign is off
2) car will not wake up using remote key fob but will on key in lock. Once unlocked and awake remote fob works as expected
Both issues doing my head in. Was interested to see that red wire bridging 2 looms in your video. I have the same and assumed it wasn’t factory
Brother, you are amazing in your expertise. The information you are providing in this video answers what I have been researching and asking for a long time.
Thank you!!!
I have a 2012 750 xDrive that sometimes throws errors on ignition start related to ABS, Parking Brake, and Traction Control. Othertimes it will show DriveTrain Malfunction. If I crank in a certain sequence it does not have the problem. I have to Power the car off, driver door as if exiting the vehicle, close the driver door, and then wait for the dash lights to go out on their own based on the timer setting. It is usually 30 seconds.
I was looking for a faulty ground wire, but I am going to check your relay suggestion as well. Very good video. Thank you!
--Matt
Invaluable information on these cars which I am very grateful of, not had any of these problems as of yet but still find this very interesting 👍
Hi great video very well explained, I have seen terminal 15 reset on my wurth diagnostic tablet when plugged into a 2012 520d, I've got no front or side left indicators and both halos not working and a long list of fault codes, can you recommend anyone who will test the frm? Is it possible to fit standard lights (not the expensive hella afl xenon) and be able to have lights without any coding needed?
I just ran across your video when I was trying to fix my dead drivers side window. Car was at dealers for new radiator. It took them 30 days to replace and when I got car back(e39 m5), the time and date had to be reset. I’m guessing that they disconnected my battery while it sat there and that has caused the window problem. When I plug in a generic diagnostic tool it says that terminal 30 is off and also that fuse1 on the GM is off. Except for the drivers side window, everything else works perfectly, each individual window works using its own door switch and also using the drivers master switch. Only the drivers window doesn’t operate and I need a logical place to begin.
Ive got this problem on my e91
I have been receiving the a559 fault for a long time and my battery is quite dead. I changed it 2 years ago and it shows me 61 and 54ah, it doesn't charge more than 49 or 50 percent. Could it be that they are poor quality batteries or a problem with the ibs? xo.or detect it?? Thank you
Dammit my friend!! If I could bet on one thing today on this 08' 328i ive got from my customer is that any person who knows that they think they know ,, well its just that, think ya know" ....LISTEN TO THIS MAN EVERYBODY CAUSE HE ISNT BLOWIN SMOKE. Any problem before you even go tearing into these rides , watch and listen to the words that come out of a pros mouth.. he just saved again for the 30th time , my time, customers being without their cars and got me on to the next customer.. Thanks again B est M echanic W orldwide... 😁🤘👍
If you want to replace the relay. Can you remove terminal 30 relay with the battery still connected? Just wait for sleep mode to engage ?
Thanks very much for sharing all that information and trust me I believe you and I honestly don’t know why anyone with a brain in their head wouldn’t believe all what you have told us either. This type of video gives everyone who is paying attention to what is being said a valuable education and if they are a owner of such BMW are also saving them a lot of money for the whole time they own the car. Even if you don’t own a BMW there is still plenty of valuable information to be gained from this video so I for one am most grateful for your time and effort in making this video and sharing your knowledge. I hope that your channel has all the success you deserve. Peace out ✌🏽
Man it's hard to watch a key being shaken about. Good info man , thank you.
😓
Hi @BMWDoctor, First I’d like to thank you for this Vid. Lots of infos that you just don’t find like that on the Web. This year I had some bad luck with a BMW F07 my battery drained out of power over the winter and on March while trying to jump it with a friends car the cables where connected on the wrong poles. Battery side. Now the nice car doesn’t do anything at all. Completely dead. Where would you advise to start checking to at least be able to unlock the doors. Right now only accessible on the drivers side with the key but all the electronics are dead. Already checked that Relais (30) you mentioned on the Vid. Any ideas where the troubleshooting should go on?
Good day, what causes the positive power terminal to get hot?
Great video! G12 bmw. Front end smash airbags deployed. Now power to the tailgate and unable to open boot. Anyway of opening the tailgate from front fuse boxes?
Thanks for making this video. I've got codes for 2DC3 and 2E8D that I've been putting off. You mentioned the clock resetting and mines been doing that along with the car not always unlocking when I grab the door handle.
Was changing blower motor on 2012 650. Didn’t disconnect battery and contacted the positive to metal where the electrical housing is above blower motor. Everything else works but car won’t start. Wants to turn over but doesn’t. Loaded question but what do you suspect blew?
I have a fault code (A0B2 Supply, terminal 30E/30L), does this mean I have to replace this relay?
Will fitting a 'kill switch' to the fuel pump as an added anti theft device to a 2014 BMW 640d cause any unwanted issues. Thanks.
Terminal 15 is hard wired / soldered to the board ? Is it meant to be removed .. mine doesn't seem to want to come off. I've got no crank , all my lights and battery are fine.
I have the same problem. Do you have any idea how to get it off?
Glenn, I have the same problem. Did you figure out how to get to terminal 15 and was there a Relay behind that cover that can be replaced?
Same question....and a second part to this, is there a "good" way to jumper the distribution to simulate that relay coming ON to test? I have no terminal 15 voltage...
Anyone sort it ?
@@mopetersen6696 I popped mines right out 2011 335i was pretty easy my relay box kept chattering and wouldn’t turn over
Is there a similar distribution box on the F10? Could that main relay affect my valvetronic actuator? I don't want to pull the top off the engine if this may be part of my issue with the drivetrain malfunction.
The terminal 30 you're pointing out, is that terminal 30A or terminal 30B?
Hey doc, firstly, thanks for sharing your knowledge, much appreciated, for I'm a first time bmw owner. So my 2008 528i started draining my battery, my scanner showed ibs sensor defective. I replaced the ibs sensor, bought a new battery cause existing battery was 5 years old, and when I go to register the battery, the scanner says to turn on terminal 15. Btw, I'm using launch creader V2. Is it safe to say that relay for terminal 15 is faulty? If so, do I just disconnect the battery and replace relay for terminal 15? I know how to check relays but my concern is that I do it using proper procedure. Please help.
Thx Dean i hope my car Starts en Run ,because its cranking but no start...No fuse are blown..I.ll hope its Runs, I.m out of options dock
He mate I did a manifold clean of soot out on my BMW 520d f10 and forgot to unto the battery now the car won't start after putting it together any help will be much appreciated sir.
Hi there, great video. My 2012 bmw is will not crank at alll. Battery is good, will this apply?
I have a 2011 528i and my relay is ticking nonstop when connected to the battery should I replace the relay?
Hello is that the audio wiring with all the different colors wrapped up in the black tape? I'm trying to tap into a speaker wire to run a low input rca box? Thanks
My car's battery is often weak even though it has been replaced with a new one, so I often unplug that relay every time I leave the car for a few days to avoid battery deterioration. However, I don't know what the consequences of removing this relay will be?
Would you have a fuse map for a 320d 2008? I’m having an issue with the electric windows on driver side and both keys stopped locking/ unlocking the car. Any is the maps I’ve looked at appear to not match my fuse board. Thanks in advance
Will it do something with the starter??
I park in the garage & in my previous Chevy Malibu, I used to just leave the keys in the vehicle. Should I not do that for my 2012 X3?
Driving to work today the dash light up everything for a few seconds then back to normal, after in the car park I was backing happened again, check error code and this came out 4C18 I believe is terminal 15, should I go ahead and replace it ??? Thanks in advance
I have two codes
CAS (Car Access System - CAS/FEM/BDC)
DTC( 1) Count
930751
Abnormal
1
Output, Terminal 15: Short Circuit To Positive
and
ECM (Engine Control Module - DME/DDE)
DTC( 1) Count
1B5101
Abnormal

Terminal 15_3, Line From CAS, Electrical: Sho rt Circuit To B+
Could this be related to relay? Sometimes there is a slight vibration that feels like misfire. Thank you for any and all help.
Fantastic information, Dean! 👍🏻
The electrical info is super interesting.
The only Bimmer TH-camR I believe ❤
Inspired by you I started my channel on Bimmers as well
I have a similar problem with a 2005 X3. 3.0. If it sits for a few days or more there is no power anywhere. When I hook up jumper cables under the hood still no power. I have jump it directly at the battery. Then I’ll g get lights on the dash. Where should I look. Is this video the same for the x3 ? Thank you from Phoenix Arizona.
I have a m57 e61 2005. Crank no start.
Car was on parning lot for few mounths and battery dead. Charged the battery and car crank but not start. What happend? Car worked fine when parked it.
i appreciate you BMW DOCTOR THANKS A MILLION .IF YOU EVER THINK OF VISITING FLORIDA I LOVE TO SEE YOU
Hello
I’m having a random no start no crank issues with my 135 2008 n54
The car drives great with no faults
And till now,happened 3 times ,it won’t turn on.
I leave it for 30 minutes, and it’s fires directly.
No codes,,battery new,starter changed 2 weeks ago ( had a code on scanner so i changed it)
I Tested the grounds,,,all fine.
Any idea what to check?
Hi BMW Dr,. Today after I started the car, my wiper started moving , central lock and trunk, backup camera all malfunction. I noticed that when its a hot sunny day, it goes crazy. When I scanned the car, I got this error "Code 8021D3 Terminal 30F: no reset / shutdown due to error in terminal 30B input" Does it mean I need to replace the RELAY ? After 1 hr , the car went back to normal. What do you think the problem is ? My car is a 2011 F10 535i
Hi just quick question I have bmw f10 and after diagnostic scan come out with terminal 30 relay under voltage is that mean I need to replace the terminal 30 relay ? If yes should I disconnect battery before replacing this relay ?
Many thanks for your response.
Is this the same relays for 2011 528i ?? No communication with dme and transmission??
So the relay 30 will cause no power at all to the cabin??? I have nothing at all. No dash no lights no nothing. The alarm wants to keep sounding too. Car was fine yesterday!
I there I have been looking at your videos great stuff I have just bought a f40 128 ti and because I work away all week when I come home the battery doesn’t turn over very good can I put a solar panel tricycle charger on the jump connection under the bonnet I used to use this on my Golf GTI and had no problems hope you can help mike
Hi Dean, do you have any experience with the error retrieved from ISTA code 000090 IKE: Voltage supply, terminal 15, faulty or INPA code 144 Terminal 15 open circuit ECU: IKI.
Vehicle: 04/99 BMW e39 m5, Symptoms: when engine is at operating temp longer than usual cranking required to start the car, but if you turn key to pos "0" and try again all is ok
Thanks in Advance
Hi my rg terminal 30 relay is clicking ..would it be stuck or jamed
DO YOU KNOW WHERE THE TERMINAL 30G-F IS ON E90, 2006 E325i, I have A731 code and 2DED code.
My radio stoped working as well. The car starts and runs well, but these codes persists and there is a slow drain on the battery, therefore is A731 code. But where is the FN terminal 30G-F?
Hi doc, my 2005 BMW e90 320i cranks but no start. I have checked the fuse and relays still no start. What I have notice is there's no power going to the coil's no spark going to spark plugs. Can help with information to fix this problem
I'm no expert.I got A731 error, terminal 30g-f.Should I just pull that black thing and replace it with the new one. I hope you reply. Thanks
Ok completely understand what your saying but if terminal 30 ever shorts out then is it possible it can drain thank you
I get intermittent no crank no start issues. Change/charge battery will be mint for a week then intermittently do it again no rhyme or reason to when it does it. Sometimes if it no crank no start leave it for 10
Minutes and off it goes. Do you have any idea what this would be would it possibly be one of the issues. I get a cas code for starter no start.
I have a 2007 550i V8 that after trying to jump start it (yes properly) I got a crank no start. Checked all fuses, have good fuel pressure and getting spark. It appears my injectors are not activating. Changed the Crankshaft Position Sensor and had my DME tested. Still crank no start. Could these relays be the problem?
@@gnptravels2540 great question that never got answered.
I am currently having the same issue Find the Issue?
Hey doc,i got a 2005 bmw 525i 5 series and i got a code AOB2 supply, terminal 30E/30L
Can't find nothing on the web for this code, do you have any idea??
@BMW Doctor
I have BMW E66 730D 2006 No crank no start, was working fan know when I push the start stop button nothing doesn't turn starter motor, lots of electrical faults on the dashboard, call Sos, safety system! , PDC faulty, go audible charm when I put the key in the dashboard, when I press it it says preheating with a coil logo, then I hear audible clicking from the DDE under bonnet pass side.
Also my radio won't show stations to tune in, no TV in back on etc, car battery fully recharged still same.
Do I have these fuses and relays as shown on your video in my version of my car E66 and would this cause these faults?
Ps car still locks and unlocks with the key fob, I was beginning to think the DDE or ECU has packed up or started motor failed, but with everything else electrical not powering on like the radio I thought it must be something else.
Please advise if these relays and fuses would cause my symptoms, and please where are they located on my model
What would cause the vehicle to crank but not start
So I replaced the battery in my 08 528xi and then went to start the next day and it was running rough and went to limp mod now it will just crank and won’t start
Great info. My car stuck in park, mechanic has had it for almost 4 weeks. I asked them to check fuses first.
Hello. Did you figure it out? thank you G
How do I replace this relay ? Done car diagnostic yesterday, and terminal 30 fault was detected. Can't find any for sale though 😕
I've got a 2007 bmw 525i e60 and I've got traction and handbrake light on but handbrake light goes red when handbrake is on. Also have abs light come on when hit 15kph do u have any idea what it could be
I swapped my fuse box due to terminal 15 failing whenever it got over 85F, now the new one has no signal to DME but everything else is great. Would you have any suggestions? IF i paid you would you walk me through it remotely?
Where are these relays found on the e90's? I've seen the relay 30 in the glove compartment, but I don't think I know where the terminal 15 and those 100amp fuses are.
Can i get a part number for the terminal 30 relay please, my 2009 535xi doesnt even have one installed.
I was away from my car for 2 years and a bunch of things are fuvked
E90 2005. Auto trans runs fine on smoth road, but once hit road bumps or hard accelerate gearbox start to fail.. Even on park just heavily acceleration makes P icon on dash blink. Where should I look for problem? I think it should be electrical fault? Maybe some demaged wires or plugs? Please help.
Where can I find the Park sensors relay?
Bmw 420i F32 model 2014
So this relay terminal 30 is always on? 24/7 my battery keeps draining and this is the only thing in my fuse box producing any heat
Do you know which fuse will cause my interior lights to stay on. For ex my lights turn off and the cluster and I drive but the lights for the shifter and AC and heat are still on all night.
I got a question, I got bmw 328i f30 2012 and I’m having trouble of finding out what’s making my car not start. I got a scan tool that show these store code from FEM which are 8040B9 : De-activtion of terminal 30B: Top startability limit reached. 8040BD : Reset or deactivation of terminal 30F. 0300A0 : front passenger door power window regulator. System not normalised. AND DME 102A01 : Air mass flow sensor, signal electrical fault, 135808 : Valvetronic servomotor, position sensors, electrical: malfunction.
Could these Intel help me indicated the effects my car from not starting? Im trying to understand where could these link too. I was told to use a insta+ but idk if it can work on a HP computer. And also told to restart the battery through a scan tool? . Cause I took off the negative thermal for safety for changing a sensor and I was told the car goes on save mode and I have to restart it? But it’s getting power. I bought another battery too cause the old one I had was bad. but It seems fine. I get in several times and it tells me the car battery low. But has a crank but won’t start. I just hope it’s not the timing chain or something else. I’m no tech nor mechanic but I’m doin my research to see the problem.
Do you know about f31 its like most of the its ok but know it would.t start for 2 weeks now first it taps the starter but it didnt turn over. Know even of i charge the batt or NOT. It does NOT make a diff but i change the batt maby it whas No good...
Anyways u get too the CAR SIT down the Lock comes off i push start it says preheat.. And then nothing or it taps the starter...
Hi Dean, I have an E70 which is having the following issue, CRANK BUT NO START, NO POWER, WAKE-UP LINE (acc) ON CAS MODULE with 0.13V all time. Already replaced junction box JBE and FRM modules, also starter. What do you think the problem may be? I'm desperate
did you find the issues?
this is my issue
Hey nellely, do you have a multimeter? If you're getting it to do a good crank (typical crank usually enough to start.) the first thing you want to do it check the ignition fuses, and fuel pump fuse/relay. Also check if you are getting power to your fuel injectors, a NC fieldsense multimeter is fastest and great for this, but if you're just fixing your own car and don't tinker with electronics much, I'd save the hundred (s) and go without. Let me know if you've tried what I said to no avail, and I can walk you through some more troubleshooting procedures. I highly recommend buying a blue driver obd2 reader. They're worth every penny, made in Canada i believe,and constantly getting updates. it doesnt use glitchy, ripped 🇨🇳 code, and is perfect for the average vehicle owner/all the way up to a seasoned journeyman mechanic when they don't want to bust out the giant snapon /autel scantool
Having this issue on f15 now
hello can i ask have you had this relay cause canbus issues i am testing one at the moment and the faults keep moving around the car ,abs ,then it clear's up terminal 15 and 30 faults then after checking connections , ok, then i had canbus faults on other modules ,intermittent faults .
Hi mate i have an ibs problem(ibs not recognized by the dme ,ibs supply voltage circuit open.Bsd interface between dme and ibs circuit open or loose contact)Made me change alternator,ibs cable etc etc.What could be the problem?
My Car does not open or close when i Push the key Buttons.
After a ride it sometimes works again . Like normal . Then after 30 min of sitting it stops working. What can this be . The key is good . Diversity antenna is good . The fuses are good .
Please is there anywhere else to find fuse to oxygen sensor heating I have tried under hood per another video and not there under dash no
Thanks for that bro. My 2008 135i has that no crank no want to go thing happening to it and every time l go to start it l get this buzzing sound coming from around the fuse box some where. What's going on there bro?

My car is giving me this error? It says FRM: Terminal 30A connection, power window faulty though. but I have abs, traction, and brake light on even though I fixed all my abs sensors and tested my passenger headlight with my other and it doesn't work even though the driver one works. any tips? I have the codes if you have time I know you're busy..
So how to fix under voltage on clamp30?
I have a 2007 530i no crank no start only now replaced starter and car delays like 5/10 secs turning n turning till it finally catches whatever it's catching to turn over all the way and start but what's causing this I'm clueless and mechanics say all diff things
Are the relays replaceable ?
Where can I find the replacements?
I have OCD... I couldn't have all those fuses reading different ways... I'd have to straighten them
do you know where i can tap to get a switched accessory 12v?
Doc please help 😊, i have 2006 e65 750 . It was parked in garage for 10months . Car not recognizing key for comfort access . Need to be insert in to work . All button on remote working.

I'm currently battling a bad IBS and battery on an 2017 F15 X5 with 60k mi. The car died, was towed to dealership they found little to none, died again, boosted several times, died again. After an CEL came I scanned it and it gave me a code for a bad IBS. The car battery won't charge on a DEFA charger (the bad IBS fully depleted the battery 4 times or more). Will be replacing the battery and IBS in one motion, the register it, reset the DME and clear the codes. If this doesn't cut it then I have no idea what to do next...
