- I show how to bypass the EWS II security system on a 1995 BMW M3. I did this because the EWS II failed and it would have been very expensive to have a BMW dealer fix the problem. $500 to $2000. dollars US depending on the dealer. This was a no crank problem started as intermittant and went to permanent. The system matches a code on a chip in the key to a code in the DME (engine control unit). by froggy
Here are some still photos of the EWS II

Dear 1947froggy, I just want to say you are my hero!, this worked perfectly on my 97' BMW 3.18is. The video can be shorted to 30 seconds where you explain which cables needs to be cut & combined. It took me 3 minutes to fix a 6 month problem. Thank You!
Froggy, you are a life saver! The transponder chip fell out of my only key when the BMW logo popped out, and I couldn't find it. My e36 325i convertible is also production date 7/1995, so I looked at the DME and sure enough, it's a silver label Bosch 413 just like yours. I jumped the green and black wires on the EWS II like you did and voila! I don't have to pay a penny to the stealership for a new transponder key, and now my car starts up like a champ! Also, I can get new keys cut from Ace Hardware or Home Despot and they will work too because the EWS II is totally bypassed! Please keep posting videos when you do work on your M3 so people like me can save a ton of money and headache! Thanks again!
+K Bear So glad this helped & thanks for the feedback. I hope other people who use my videos to get their car running and/or save money will post back, as you did.
:)
did this really work for you? i'm in the same predicament where i lost the chip out of my key and couldn't find it, and currently waiting on a new fuel pump before I can try and start it again new with the wire jumped.
@@wettsoggynoodles Yes, when I did have that 325i years ago I jumped those wires and was able to bypass the EWS II, energize the fuel pump, and start the car without the chip. That was years ago and I no longer have the car, but as long as your E36 matches what froggy said then it should work.
Make sure to follow up let us know here in the comments how it went for you after you try it.
You didn't have bypassed the EWS2. I try to explain why this "trick" does the job on your car. When you turn your key, the EWS2 check if you have a good key (password check). If the check is successful it switches a relay inside of the EWS2 unit. This relay simply connects the two wires you have connected manually together. These two wires are only for the starter. BUT, the EWS2 does more. It sends a coded signal to your ECU on another wire that the ECU should allow the following start. So, whats happend in your car, is simply that the relay inside the EWS2 has failed. This means, that you just have bridged the relay, and forced the starter to turn, but you cannot prevent the EWS to send signals to the DME and check if the DME and EWS2 are aligned. If the start was successful your EWS2 sends a new "password" to your key for the next start via the ring antenna and only this password will "unlock" the EWS2 for the next start after the ignition was shut down for 10 seconds at last. I bet, if you remove the chip of your key, the car won't start. The car will crank, because you connected the to starter wires together, but it will not start. You can not disable the EWS2 with cutting and connecting wires. If you will fix the failed relay inside of your EWS2 and reconnect the two wires back to the ESW2 your car and start immobilizer will work as designed.
You are probably correct, this "tricks" the ews2. I don't have the time/tools/parts to fix it as you describe. Mine works.
Thanks for the thoughtful comment.
:)
Which relay is it?? You sound like a bmw mechanic!! We DIYers are doing this ourselves....with no help. And we sure in the hell are not coming to your stealership!!! Because honestly that all what these relays and modules are about!!! They go bad so people can come to the service department and you the advisor tell us its a head gasket blown....overly charge us.....change the relays or module....and the car works fine... While we pay thousands... Hell no!!! Thanks froggy
Mr3, THANKS for a very clear explanation: this is the ONLY way one can do repairs,by KNOWING; thanks
thanks for the thoughtful insight and time to type all that. That is great insight so we others can innerstand the system and what's happening.. people who are thinkers will use this to investigate the bigger picture and see it.
thanks
Thank you sir! You are a gentleman, a scholar, and a fine judge of liquor.
Just wanted to clarify something. Your wiring modification jumps the starter relay which is located inside the ews module. This however does not disable the EWS system. if you tried to start the car with a chipless key it would crank but not start because the ews still inhibits spark/fuel. Similarly if a different component of the EWS was to fail this bypass would not fix the problem.
This is right. My e36 1996 can crank with no start
Can any body help me to start?
1997 328i - Works!!
I missed work today because of this. But thanks to you I'll be there tomorrow. Can't thank you enough!
hi Brian that's great I'm so glad my video helped you
The ews bypass is used when you have diagnosed that the ews circuit board is broken. ALL other components of the starting system including the chip in the key and the antenna around the key, must still function. All I did was bypass the ews circuit board & it started & ran as new.
FYI! I JUST BYPASSED 2000 X5 E53 4.4i EWS AND IT WORKED FOR THIS MODEL TOO ! THANKS A MILLION FROGGY!!!!
Wow, I am glad it worked, but also surprised. I only documented it to show how it works on my 1995 M3.
So that is great to know, thanks a LOT for the post.
:)
AFTER MANY HOURS OF BIMMER FORUMS AND TH-cam DIY VIDEO I QUICKLY LEARNED THAT YOUR REMEDY WAS THE MOST EFFECTIVE AND MORE LIKELY TO WORK (SO WHY NOT TRY IT IN SAME STEPS YOU TOOK BUT ON MY E53 4.4Ii X5). EVERYTHING ELSE JUST DIDN'T MAKE SENSE BASED ON EVENTS LEADING ME HERE. REPLACED BATTERY, REPLACED FUEL FILTER THEN NO CRANK NO START. SOMEWHERE IN BETWEEN THE EWS AND DME ACTIVATED THE ANTI- THEFT SYSTEM NOT AUTHORIZING IGNITION TO START ENGINE. I WAS TOLD I NEEDED A STARTER OR BANG ON IT TO UNFREEZE IT BUT AFTER BY PASSING IGNITION STARTING X5 FROM STARTER I KNEW MY STARTER WAS FINE. SO THEN I DECIDED TO TRY "THE FROGGY METHOD" AND WITHOUT A HITCH THE X5 STARTED ON FIRST TRY. THANKS AGAIN FROGGY
AND THANK YOU TH-cam!
Glad that it helped & thanks for posting the comment.
:)
Froggy. thanks for this great video man. i have a simple question. Do you need to plug the EWS back in for the car top start? I removed my ews and the car turns over but no start.
I have a 2004 BMW 525i Touring...... It some time starts and some time do not. I suspect the key is not talking to the receiver assembly. To get one new key here (Norway) costs 550 USD :( and then also I am not sure whether it will fix the problem and work. Any possibility to bypass all these "great" features and at start my car and keep going.... The car sometime do not start (After few days it will start and work smoothly like nothing happened. I think the transponder on the key does not talk to the receiver on the steering assembly (When the car do not start, Dashboard do not start or light up - No Crank - No Start - Power seat adjustment, power windows, steering level adjustment, central locking etc all work - Battery Good). Private mechanic could not find the problem after troubleshooting for 5 hrs (120 USD $/per hour). They say they do not get any error code and they are not able to find the problem. BMW say they cannot assure to find the problem and it could take 1 hr or even 20 hr ( x 150 USD $/per hour) to troubleshoot and identify the problem, and also they do not commit they can identify. Repair cost will be extra. on top of this. I am in a dead end situation. Any help is very much appreciated. jcbjse@gmail.com
Unfortunately the start "security" systems change a bit year to year. So what worked on mine might not on yours. Try to find an INDEPENDENT BMW mechanic with GOOD REFERENCES and let him try. That's crazy money for a key, try amazon/ebay? Has to be exact key for your car/ignition system I had a spare key for one of my Vettes & no wear on it, so when my "main" key went bad, just switched. Always have 2 working keys any car. Thanks!
@@1947froggy Thank you very much. I will try to find a independent mechanic.
Thanks for the kind words, I do sometimes "over explain" stuff, but my viewers include folks that are really new to auto repair up to technicians that do it for a living, so I am always balancing being brief with verbose. And I do like to throw in little tidbits that may be slightly off topic.
Cheers!
froggy yes I have a BMW I8 when I tried to start it it won't start but the alarm is going off when I say when I try to start it it won't turn over or make any kind of noise just alarm go off if anybody have any ideas let me know please thank you
I'll be giving this whole thing a whirl on my 95 325i Convertible tomorrow. I *think* I've narrowed my problems down to this EWS nonsense. Great tutorial, froggy. Thanks so much!
Please comment back how it goes.
:)
froggy Well. I did it. Key works every single time now. Come to find out though I had my main relay swapped with my Fuel Pump Relay. I still can't get the fuel pump to turn on. Only when I manually force it to turn on via 12V. Any suggestions? Anyone? =\
Well a relay is sort of like a switch, if you swap one for the other it doesn't matter, just a switch, so long as the "rating" is sufficient. Coul be a BAD relay, they were out.
ATCRyderX© did you find the answer to your problem got same issue after bypass ?
Gary Van Hoozer After bypass, I can crank all the time but still no fuel pump or start.
It's common for some oil to be in the wells where the plugs are. Valve cover gasket kit includes new gaskets to fix that. Would not affect starting. You may have a bad solenoid/bad starter, but I can't be sure.
Back in the day one guy would turn the key and one would take a long tool and bang on the starter, be careful. You could short out the wires there.
Can you take a reader & get some codes?
Jumping those two wires takes ignition switch cranking voltage strait to the starter solenoid. It just bypasses the internal relay of the EWS2 module that closes the crank circuit when proper conditions are met. After the key, antenna ring, transmitter, EWS2 module, and DME all shake hands meeting starting requirement, the car will start. The DME also controls fuel injection and igniter packs. The rest of your EWS2 module must have been ok. 🤷🏻♂️
Could be the case, these are quite different year to year, mine I did not need to touch the DME (1995) but later years got more complex. Worth a try if you can get the parts. I don't know if there is a SEPARATE chip for ews in your DME.
What year is your car and what month was it built? It seems that BMW changed this system almost every year.
My solution is for 1995 M3 only.
Cheers for showing the bypass. I used this mod on my 95 E38 750IL and I got the engine turning over, but no start.
It uses the same EWS II system, but the difference is the DMEs ( Engine ECUs) have a rolling code that comes from the EWS to enable the fuel and ignition circuit.
Therefore, without the EWS working - the DMEs won't wake up to RUN the engine.
What I have confirmed, is that the EWS is cactus. The BMW INPA software shows that it's not getting the signal from the keys either.
So how you fix it?
Hi Gene,
Thanks for checking back. I found a few of the emulators, it seems some (all?) need a diagnostic tool to program the emulator to the car. The difference, it seems, is my procedure does not require these emulators and does not need to be programmed to the car with a diagnostic tool.
Other than those points it seems they accomplish the same thing, get the darn car running!
Thanks!
Andrew, did you confirm that the fuel pressure is within the proper spec before you crank?
From what I see it's NOT ews, a bad ews would not let you spin it over.
Hi thank you for the video , I have ews2 on my 96 m3 and same issues , I had to get the key reprogrammed and worked but after the car was under mechanical work I had my battery un hooked and it was like that for like 6 months and so now it won't start . I'm thinking doing the bypass your way . Is your m3 still running good ?
I sold it. ;0
Thanks, found this old video and helping me a lot on what wires to head for.
Good bypass, for others that cant do all that. You can get a DME, key w/ tumbler, and EWS from a downer car (bout $250 for set / ebay). Install ignition (key), EWS module, and DME in about half hour. The car will never know the difference, no programming (plug and play).
Thanks for the bypass tip, sure I can use in the future.
Guys & gals, I don't have specific bypass procedure for every year & every model of BMW. There are changes. This is for 1995 m3 and "MAY" work on some others.
Hello froggy. After you jump the wires together from the EWS do you plug the yellow connector back in? Never saw that in the vid. Also thanks in advance
I have the saem question.. does he connect the ews back? would this work if ews is damaged?
Yes you plug the connector back in, and depends on what the damage is to the ews.
:)
1998 BMW 328i wont turn over with the key but if I shouldn't the starter it will run
Did u start it with the ews module out?
froggy, thanks for the response. I've read that in the event the air bags are deployed there is a wire that connects to the battery not sure where it goes but goes bad. what happens is car won't start all doors unlock and 4way flashers come on. one very strange thing that also happens to me is the 4way flashers came on when I reconnected battery.
+Anthony Anderson I think that you may want to proceed with a connection between the airbag & the issues. Please post some comments as you go, it will make the video & the subsequent comments more useful to others. THANKS!
:)
Does it spin over or just give a weak try to spin over?
Hello, Froggy! Thanks for the video. I had this exact problem, I would turn over and nothing would happen. Similar to the example in your video. I followed your instructions and now the engine tries to start, however it just sits there emptying the battery trying to start. Do you have any idea if I can have a problem with fuel not reaching the engine or something similar? What do you suggest I do to find out from here? Thanks a lot for the video once again!
not too clear which two wires you jumped/connected Froggy . I got the two you cut.
Check the spark at each one of the 6 coils, one at a time. They all need good spark to fire it up. How good/old are each of the injectors?
Do you know anything about EWS 3.3? Will I be able to cut and fuse the wires together like you did in the video?
Greetings Froggy I followed this procedure on my 97 (10/96) 528i with an EWS 2 system, it was located in the same place yours was with a few differences, I to had the no crank problem and after splicing the two thickest wires on the EWS connector I finally got it to...crank! .....
Hmmm. The history of BMW EWS security is that they added stuff every year. In 1995 it killed fuel & starter. In later years it "could be" more was disabled. You need to see if power is getting to the coils. How did you diagnose "no spark" What specifically did you test?
I've got the same issue my key ring antenna is damaged vehicle will not start I did the bypass it cranks but I'm getting no fuel at injectors was there another wire cut at the DME
I have just done this to my 95 328 and it worked well. Considering I did the full replacement of ecu, ews just two years ago at the cost of $300 I was skeptical but sure enough...........it did it again. So thank you Froggy for your efforts and your posting.
Thanks for taking the time to post up your success!
:)
In your video, did you start the car without the "Ring Antenna" attached? Or did you start the car with the new "Ring Antenna" AND a "Chipped Key?"
I still needed the ring antenna & chipped key, only problem was the circuit board.
:)
Very clear and understandable video. I am mechanically inclined, but I have a 99 323is and I am going to investigate this scenario. I was lead to believe that I have a bad DME, but it could be a bad EWS I suppose. the car turns over but no start no fuel pump no power to DME. If it is the security module, I wonder if this will work on mine. I’ll try hopefully in a week and post. Also my son found a 96 318 in really good condition. Only the owner says it has “a bad security module” so that would be a win for that too. Thanks
Good luck, post on your progress, thanks!
hey, i have same symptoms as you. my issue on top of the crank no start is i think i accidentally opened my key and lost my chip in it without realizing because i checked mine just now and it's not there. did the bypass work for you?
I have a 95' 325i that has no crank issues. Ok, so I've done exactly what you did. I have not yet put evwrything back together (manifold, bc I thought it was starter), but after bridging the two wires it cranked after not doing that before. I'm reading about this stuff online and everyone is saying that bridging the two wires will indeed make it crank, but NOT turnover. But in your case, that is all you have done, correct? Just want to make sure, I'm hoping I'm having the exact problem you had
Did you plug the ews back in after the wires were jumped?
and if there is not what is my next step? im very mechanical but this harness is pretty crazy. I am thankful for any help!
Hello Froggy. first i want to applaud your thourogh understandable video. my 2 green wires on ews antenna broke and antenna uncoiled from its seat. do i need to replace or repair it or just remove it before jumping the two wires at the other end and when taking cables off the battery which one do i remove 1st (returning cable which 1st?
My video works with a correct functioning antenna & key chip, so fix those first (not very expensive) then if the ews2 board is still causing a non start you can jumper the wires as I demonstrate.
:)
As I worked thru mine, I did find a guy in CA (I believe) who had a web site & rebuilds the ews circuit board, but he only does certain ones (as they are different year to year). He could not do mine but maybe do yours, cheaper than new ones from dealer. Sorry I do not have contact info, but if you google enough you should find him.
On my 95 ews killed the fuel pump and the starter, not sure if it also killed spark. Once I did my bypass it just fired up & ran. German anti theft laws required car makers to up the security in later years, so you may have an additional level of security to bypass. Post a comment if/when you crack it. Wish I had more.
:)
I have a 1995 525i E34. My car won't start/crank. I have the same EWS 2 version but, I noticed there are two black wires on the yellow connector that about the same size and I'm not sure which one to cut. I'm trying to see the close up angle on the connector in your video but, it's too difficult to tell. Can you let me know the location of the black wire? Thanks!
Hi Chris,
With the bypass I did I still have a key with a chip. Not sure why but that's what worked. Go figure.
Hello, Once you cut and jump the two big wires for the EWS do you need to plug the yellow plug back onto the EWS module before starting the car? Or do you leave the yellow plug unplug?
So sorry that car has been gone for years, I don't recall. :)
I have the same problem dude! I had to query so many different ways to see if anyone else had my problem. Lights are on, but no one is home!
I will be checking this out tomorrow, I am glad I will not having to be taking off the undersides of the drivers side dash, I read about the jumper issue but your video makes it pretty clear! THANK YOU!
Scott McNeal I will be away for about 10 days, but feel free to post questions & I'll catch up when I'm back. Good luck.
:)
Greetings Froggy I followed this procedure on my 97 (10/96) 528i with an EWS 2 system, it was located in the same place yours was with a few differences, I to had the no crank problem and after splicing the two thickest wires on the EWS connector I finally got it to...crank! Lol but still no start, I feel like I made progress but I may be missing ONE LITTLE thing to make it fully start. Any input would greatly be appreciated for there are ALOT of people with e39s who are in the same predicament
did you use a seperate piece of spare wire to connect the two? you described a green and a black wire but you were holding a red one. Do I need to use a seperate wire?
+adam moore Well, yes, an extra piece to allow some room to work, color does not matter for the jumper piece.
:)
Hi there froggy,I have a bmw 318i the car was completely dead I followed your instructions and joined the 2 big wires together then the car would turn over but not start. I think it is still immobilised do you have any thoughts or ideas on how to get the car to start. Many thanks for posting this video u have been very helpful. Is there any way to communicate with you other than you tube if so please let me know.
Yours is a different car, so the security systems are likely not 100% the same. Turning over means you have successfully bypassed the starter kill. Now you need to determine if fuel or spark is missing. Do the standard tests for fuel & spark.
:)
Neonsmaw did you figure out how to get spark?
Great video. Bypass worked for me. Fired up first try. I didn't even bother messing with the key antenna. Mine is a 01/95. For those people saying it doesn't work for them, I believe is because this is for obd1 with ews2. The later models had a fuel and spark cut along with the ignition. Thanks froggy.
I have a e36 318is from I think January or February 1995 with OBD1 will it work ?
Do you know how to do it the the fuel and spark ? I have a 99 M3 auto and I need to do something similar but would like a more confident plan
death by sr20 do you know how to do it with the fuel and spark cut out ? I have a 99 M3 auto . Thanks in advance
okay awesome after chasing fuses, relays and starter watched your video followed you hello again she starting cranking, but I'm not getting fuel. I checked it with starter fluid and almost started. any ideals? I know you said the ews blocked the fuel/spark also.
What year is your 3 series?
Correct, if I was not clear on this, sorry. I think I did say you still need the chip/key. It's a very "insidious" security system, for better or worse.
I've seen many videos about bypass. Most of them are extremely complicated and require more than basic skills with a solder iron. I will try this method on my car if and when I install remote start and start button. If it works it will save me a 100 hours of problems. Thank you very much for the video :)
+MrRoyalbeers Hope it helps, it fixed MY SPECIFIC problem 100%. Trouble is some people have a different issue and think THIS will fix it, not so much.
:)
As I understand it, and I don't claim to be "expert" in this, the bypass "allows" the use of the red label dme, but does not "require" it, I just kept the original dme & it worked.
FYI, very important, there is also another wire to cut so that your DME is not looking for the signal, I would recommend doing both this procedure and the other ..
both together.
Thanks, for MY CAR this was all I needed to do.
:)
So which is the extra wire to cut? E39 528i cranks no start
Could we know please which wire to cut if the car now cranks, but is a no start after splicing the two thickest wires. I've read pin 4, which should be green, but mine is black :( Or if there is any other alternative.
I have a 95' 325i that was not cranking. I thought it was the starter, so I replaced it and it still no crank. So I went ahead and did what you did and bridged the two wires and it cranked up. Now, I haven't tried to fully start it yet bc I forgot to put on an important hose so had to take manifold again but am doing that after work. I've been reading that this will only make it crank and not start, and im worried mine will do the same. So ALL you did here was bridge the two wires. Right??
Now I can get to work tomorrow morning!!
You the man Froggy!
Many Thanks
Glad to help.
:)
hello did you change the ring antenna ore dosent matter if thring antenna is bad ? thanks
i have the same year and model of car, how did you fix your no crank problem. i connected the two big wires like the video says and it cranks but doesnt kick over. is it the coils??
You need to test if you have voltage AT the starter when you twist the key.
hello, im not native american or english and this question is probably a bit silly.
As far as i understand all you did was to loop #1 and #3 out of the ews2 control unit and left the DME untouched in original condition, am i right?
going to try this tomorrow, thanks in advance.
I have never heard of a connection between ews and the hazard lights, but could be possible?
I am thinking starter also.
Could you push start it to see if it runs once it starts (careful) You would need a couple of buddies & a hill.
:)
Thank you so much for this. This fixed our problem exactly. We just did a manual swap on a 96 e36. Worked perfect untill we drove it home, all lights on and no crank. Replaced the starter, changed nothing. Cut the same two wires and spliced them together and presto!
Great that this old video is still helping, have fun with the car!
:)
Did you get any reply on this or did you perhaps find a solution yourself?
Both fuel and spark are missing we have checked fuel pump and spark plugs and we have checked it's the same ews2 , if you have thoughts or suggestions on how to pass the immobiliser. Thanks for your prompt reply all the way to Scotland .
Is the key chip and the antenna at the ignition switch present & working?
:)
Hey frog quick one for ya just got a 95 325is same problem as you. So when you turned key in on position did fuel pump engage ? Or just silent and no crank no start. Mine is silent and wondering before I try your solution and jump the wires
Total silent when mine was having the issue.
Chris Lyon is your car automatic or manual?
Stick.
Where did you get the i formation on location the schematics you showed where the ews is and goes to
Old school way was if the starter clicks but no spin, bang on the relay if you can reach it, it's on the starter. If that spins it you have a bad starter/relay. Always be looking at your elec. wire connections for short/fray/break.
:)
hello how u doing ... i have a bmw 1995 325i with a 110k every thing was fine till few days ago the gauges on the cluster is not working the fuel an the temperature the speedometer an the rpm not working but the car run an drive fine the lig the signals is working....an another thing happend that windows stop working but if i take out the cable of the battery for a minute an but it back everything start working fine ... idk if u have any idea about this problem
just done an M50 engine conversion on my buds compact with ews2 and have come to the no start problem, will try this at the weekend and hopfully it works.
thnx for the simplicity of the vid :) this stuff gets overcomplicated very easy
+SuicidalSlider Good luck & post back how it goes.
:)
Nice vid froggy! If i change my ecu to a surplus donor ecu with same part number, then i do the bypass, will it work? Bec i bought a surplus ecu, plug it in but yeah, didnt even crank. :(
I never tried to change the ecu, but I think it needs to be "paired" sort of to the vehicle. Maybe tech2 or trip to dealer.
When I turn my key to on, I'm just getting the airbag light. Were you getting lights with the no crank or did you not get dash lights as well? Needless to say, I get no crank. If I test my fuses... I'm getting no power to quite a few fuses including starter, etc.
Honestly I don't recall which dash lights I got, it may show in the video if you ck it again. Sorry.
:)
We cut the two wires and connected the EWS. Now the starter is cranking but still no spark and no fuel.
Hi froggy I just wanted to know if a remote start solve the problem too? I have a bmw e36 328i sedan.
Even with a remote start I would think the broken EWSII would prevent starting.
:) IMO
Thanks for the info and do I just buy the EWS II module and plug it in? By the way what color would the connector be blue, yellow, or white? It would be great if you could help thanks.
Each model year can be different.
:)
If it EVENTUALLY starts and runs, then IMO I don't think it's EWS. EWS does not "give in" after extended attempts at starting. Nonetheless, watch the video carefully, it shows how to disable EWS.
You have changed a few things that make the situation different from my example on a stock 1995. If you hear a loud click, that sounds like power is going to the starter. When mine was dead I could not get any power to starter, so this sounds different. Did you try a jump start or different battery, a loud click with no crank usually means a weak battery.
:)
well i already bought a chiltons manual so i guess ill look at that. i hope its the filter. i dont want to mess with the fuel pump. the back seat comes off really easy so i guess ill start there. thanks for all your help. i can give you updates of my progress if youd like
I have the exact same problem as you. Hoping your account is something you check despite the name being sort of not indicative of that I would love to hear if you fixed the problem.
I do have the same problem with my BMW 320d E46 2001,do you think that if I do the same thing to mine it will work?Thanks
For Jason, I'm glad it helped you.
:)
saya telah melihat vidio anda ini. saya tertarik, dan punya masalah yang sama seperti dlm vidio anda ini. mbl saya BMW 5210i. apa blh di jumper jg? gmn detailnya.....
I translated comment, but do not understand question. Sorry.
:)
Terima kasih. ?...
froggy hi froggy great video . Would you have an idea on how to do it with 99 M3 that I think has the fuel and spark cut off . This is really a pain in the ass
With your experience, do you think that I will need a red label dme to start the car?
Now what if its already disabled the fuel pump. Will this work? Or is that for the starter only
Sorry car long gone, not sure. :)
Hi froggy. so i got a 320i e36 95' the wires you have cut black and green, you tied them together?
this is smashing Froggy. I wish I'd seen this before I got ripped off. I have exactly the same problem and they still cant fix it. bless you sir,!!!!!
Do I put back the yellow plug back after bypassing those wires. I bypasses the wires and I haven't put back the plug. There is no spark and fuel at the moment.
Hey, so am I suppose to take out the tumblr or does it have to do with bypassing the ews system and getting a new key? Do have the original key by the way. Car was starting fine until one night it got stuck on accessory mode so I unplug the battery. Once battery is plug in it goes straight back to accessory mode even without the key in the ignition. Been had an issue with the key spinning but never had it stuck on accessory mode or with the car on till a few nights ago. Also, it's hard to get the key to spin, have to play with it and even if you get it to spin it won't even crank or be able to turn the car off. Please, let me know. Thank you.
Your issue seems to be (as you describe it) all to do with the key and ignition cylinder. Does not sound like EWSII
i speak english a lot, but i have a question! The problem fix only jumping the 2 wires, or do something on the DME ECM?
What I present in the video ONLY involves the 2 wires.
:)
couple questions:
You cut the two biggest wires - green/brown and black/yellow on the *plug* side?
Then you connect them up on the *plug* side as well (as opposed to jumping them on the EWS module side)?
Did you reconnect the EWS plug to the EWS module?
It looks like I need to do this today, my car stopped cranking today. It had stopped a couple weeks ago leaving me stranded, but a new key fixed the issue. Now it won't crank even with my new key. :(
Watch the video at 15:00 CAREFULLY, replay it a couple of times. Yes you have to reconnect the plug.
:)
froggy It's weird, but this doesn't work for me. Your ecu looks like mine, I've spliced the wires together as you did, but no joy. :( Mines a 3/95 car
Sorry, so you have no starter crank and no fuel pressure - you measured it or listen for the pump to prime? Those are the two symptoms of a failed ews2.
Hi Froogy l have recently recently purchased a RHD 96 E36. My car is automatic and l wondered why it was able to be started in gear instead of only in park or neutral, after taking out the glovebox l noticed the two heavy wires you refer to had been disconnected from the ECU (somebody has discarded the device) (gone) and joined these two wires together. The plug is just hanging there now and doing nothing. Initially I assumed the starting fault was caused by a faulty inhibiter switch on the gear change, after watching your video and reading other comments. I am reluctant to replace the inhibitor switch if that's not at fault and I've gone to all the effort and expense to renew it to then find out it's not the problem
If anybody can offer me any assistance and advice l would appreciate it very much.R.
Kind regards from New Zealand.
Not at all sure on that, immobilizer is for security/stolen car, nothing to do with starting in gear that I know. Good luck.
Thank you so much froggy!! I have the same problem with a 2001 525i. You gave me some great direction. Now I just have to figure out which wires will bypass my ews... Thanks again for the great video!!!!
Thanks for watching, be advised, there are changes from year to year, a copy of what I did on my 1995 may not work, just sayin.
Good luck.
froggy brother my car is 1995
fation ismaili should work
Hi, a pro mechanic fixed the issue on my car, 318is 97 Manual, this info may be useful to someone else here.
The no crank issue was located on the clutch pedal. The EWS does not affect the starter, it locks the engine only (at least on my model)
When you push it, the clutch pedal makes a bridge connection that allows your car starter to crank, if you have a no crank issue, you should check the clutch pedal connection first, a slack cable on this connection was the issue for me.
Cheers!
Here's my issue, 6/95 Build Date M3, 3.2L OBD1 Swap, I used a red label chip in my 413, and snipped green wire 66 on the port or 7 on it, can't remember. It started right up. Flash forward 5 months later, my car will not crank! I hear a loud click noise and the hazard lights come on? Do you think this jumping of these wires will solve the no crank issue? I'm not sure why the hazards come on? If I double lock the car and unlock, it goes away then comes back.
Did some digging around, got the car to tumble, got the fuel pumping to the engine. Just one little thing I'm missing. Seems I'm not getting any spark. But everything else seems to be functioning. What can be done to the DME? Any helpful websites?
I had the same symptoms and I jumpered the two big wires on yellow clip but it only fixed not cranking. Still no start/fuelpump/spark. I did it on my 1997 328i. Obviously they were different cars. Any help appreciated.
I would just be guessing, sorry.
Good luck.
:)
Freehand did you figure out how to get spark and fuel?
Freehand did you ever figure this out?
Just to make sure, to bypass the EWS in the glovebox you just cut the two biggest wires on the yellow plug and connected them together?
Review the video at the 12:00 minute part. This is reversible if you do it neatly.
:)
froggy are you sure its ews II ? I did this same exact thing. I bypassed the ews by cutting the two biggest wires from the ews harness and connected them together. It cranks now but does not start. Maybe the difference is the dme? I don't think it's the a 413. If you have any idea why it's doing this, let me know. BTW the car is a 98 bmw 318ti. Thanks
Ricardo Nelson BMW made/makes a lot of changes to the security system from one model year to the next as the German government changes the anti theft standards.
My fix works on that 1995 car but I can't say if it'll work on a 1998, wish I could say more about it, yes it could be changes to the DME that are at issue with yours and yes mine is EWSII
Glad it helped, fwiw I think the little circuit board just fails (or some tiny part on it fails) after xxx years/miles. It's too bad the manufacturers have to keep putting more and more complicated anti theft systems in, but the consumers & the governments demand it & it's tough nuts to the second/third/forth owner when it fails. Locked out of your own car now that sucks.
:)
The links in your description did expire. May you have backups or a way to locate those again? I'm running into the same issue.
same problem man, no fuel and no spark, no sure how to bypass thought id see if you found something i didn't. lmk thanks
you right bro i did the ews by pass and still the same issue let me explain the problem that i just saw so at cranking there is no spark but if we press the gas pedal like three times eventually it wil fire up and give out spark weird right any way ill post more results latter and thanks for t quick response froggy
Put a fuel pressure gauge on and turn the key on, look up what the pressure should be.
Greetings Froggy. I followed this procedure on my 97' 318is. The key was broken and I now have a key without any chip. Before I followed your video my dash would light up as normal and then nothing. Now I hear that clicking sound when i bounce the starter but no tumble. Any suggestions as to what it may be?
Thanks for the post. On mine 95 m3 ews2 there does not appear to be a rolling code. Once the bypass was in, it started & ran like a champ.
Having said that, there are clearly differences from year to year and model to model.
You really need to research what you are dealing with in each case & not just try the bypass and cross your fingers.
