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!

Thank you sir! You are a gentleman, a scholar, and a fine judge of liquor.

1997 328i - Works!! I missed work today because of this. But thanks to you I'll be there tomorrow. Can't thank you enough!

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!

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,!!!!!

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!

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

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!

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!!!!

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.

Now I can get to work tomorrow morning!! You the man Froggy! Many Thanks

Thanks, found this old video and helping me a lot on what wires to head for.

Thanks! Really saved a lot of my time and money. Do more videos like this, really appreciate this!!!!!!

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 :)

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'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!

This video solved my no crank! Great information thank you. My car is a 1996 ews2 318ti with a swapped m50 vanos with a red label 413 dme.

FYI! I JUST BYPASSED 2000 X5 E53 4.4i EWS AND IT WORKED FOR THIS MODEL TOO ! THANKS A MILLION FROGGY!!!!

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!

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.

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 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!

Good info. On my 1995 this is NO clutch pedal switch. So this shows how each model year can be VERY different, which I have mentioned many times. Thanks for the comment. :)

Where did you get the i formation on location the schematics you showed where the ews is and goes to

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

will this work on a 1997 BMW 328i convertible? keys were stolen antenna ring wires are twisted off thank you so far

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 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!

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! .....

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.

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.

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.

i just done a conversyion used all the rite ste stuff and im still havin probss with starting no igition ay all execept reds on dasdh my car 1995 emws i wanna get rid of the w sysyem but if u can find way to crank car i need help

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?

Thank you so very much. You are the greatest help Ive had in years. I want to know what causes this problem but I can live without knowing. Just amazing I could get it to run from the solenoid on starter but just couldn't get it to go with key been driving me crazy for about a year now thanks again so much..... priceless info...this was on a 01/95 325is

Did you plug the ews back in after the wires were jumped?

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?

Does it spin over or just give a weak try to spin over?

Thanks Man, it's good to know. 1995 2000cc M52 automatic

hello did you change the ring antenna ore dosent matter if thring antenna is bad ? thanks

For Jason, I'm glad it helped you. :)

hi Troy,I fix emulator to DMA comp.that the immo don't work anymore and bypass in ews from Froggy video

froggy, would this procedure work to eliminate a key all together? i have lost my key and bmw wants a couple hundred bucks and a 4 hour car ride to the nearest dealer to produce id and registration. i know the ignition stitch pops out on the opposite side of the colum and can be engaged with a screw driver .any thughts?

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?

I tried the stomp test and didn't get any code other than 1444 which read there are no codes stored. I'm really thinking it might be the starter, but this was sudden and not intermittent which makes it even harder to diagnose. I had Jo previous symptoms, the only thing that would happen occasionally was my flashers would come on and then I had to push the hazard light and it would turn off. Any idea what that might be? I thought it might relate to ews.

Questino.....The yellow plug at the EWS computer is wired different for my car '95 525I E34 3/95 production. From the back of the plug RT to LT #1 BLK/YL (thick wire 14G?) #2 WHT/Purple (thin wire 20G) #3 BLK/YL (thick wire 14G) #4 GRN (thick wire 14G) Any ideas

Will this work on e36 m43 engine

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.

You need to test if you have voltage AT the starter when you twist the key.

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.

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.

I have 2. Black/yellows (95 e34) and the green do i link all 3? Tried the 2 specific ones from video (blk and grn) and nothing.

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?

Thanks man, worked like a wonder. great job.

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?

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.

Quick question my 325is built date next to the driver door says 12/94 but the title and all the documents say 1995 do I have EWS I or EWS II ? Greatly appreciate it

Hey I need help with my e36 it won’t crank up with the key

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!

not too clear which two wires you jumped/connected Froggy . I got the two you cut.

Hi, I have 1997 bmw 528i and want to bypass the EWS please help.

what dme is in the car? i have a 282 that i need to disable the ews on.

Hi I need help on my 2001 bmw 325i also have similar problem..no crank and just bought a new battery. i try self diagnosis and it came up with code P0604- PCM Random access Mem (Ram) error and also showed EWS and UCU issues. so do you have a way of resetting the EWS or modules?cause i think it just lost memory! thanks your help will be highly appreciated

Hi all! Can somebody help me where can I find the ews module in my e38 728i 1996 car? The immobiliser doing the same thing like in the video (it is doing nothing when I try to start the engine) and I decided to bypass the system. Please help me solve the problem. Thanks!

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 wires did u jump the 2 big wires

It is a loud click that's distinct. I tried jump starting it and nothing. I can try to see if it's a bad battery. But sounds starter or ews related, any ideas? Will oil in spark plugs cause the car not to start?

Very informative If you still can't fix on your own, there are auto locksmiths that can fix these . MUCH cheaper than dealer. They have a tool to test the antenna and diagnose. I had E 46 issue with the key , the locksmith cut a new key and matched to my EWS.

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. :)

OMG I'm so thankful for this video I'm jus keeping my fingers crossed an praying that it works I barely bought the car about a month ago n my car is doing exactly like this video.. God bless you thank you so much .. Pray it works for me thanks! Also what is the pricing on the AWS BYPASS? And we're can I find one that's cheap??

Hello froggy, I've got a 1995 bmw 525i I had disconnected the battery to remove air bag on steering wheel. reconnected battery with out connecting air bag. now car wont start power windows don't work pwr door locks dont work. Is this a security system issue also any idea's how to diagnose?

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?

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.

Hi froggy. so i got a 320i e36 95' the wires you have cut black and green, you tied them together?

Hopefully it helps someone with a car model like mine, by the way great videos!

will this not crank but also kill the fuel pump? I had this issue but at first I could push start it, but then It stopped push starting too, but after a couple days would work normal again?!?!??

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??

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.

Omg extremely helpful vid thanks m8

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.

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!

Having this issue on 1997 e39 528i would this be the same bypass setup ?

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?

hola soy de panama podrias mandarme la traduccion de este video tengo un bmw 318is del 97 automatico y la llave con chip no arranca de pronto la antena esta rota donde va la llave en el cilindro ..esto me podria solucionar el problema que tengo ..que tendria que haser por fabor ..gracias

someone please help i have a 97 bmw 3 series 1.8 i had a similer problem to yourself froggy i broke to green wire on the ews ring so re connected it and worked fine at the same time this happened the starter packed up obv i thought was the ews ring i put a new starter on but noting wont start from the key. i do have power to the starter but would it stil have power if the secure system was ingaged ?

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.

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?

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. :)

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

I did that it cranks but no fuel cut out any help

Now what if its already disabled the fuel pump. Will this work? Or is that for the starter only

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.

hey froggy... i have a 98 e36 my fuel pump turns on. but i still have a no crank issue. new battery and the dash lights turn on when the key is turned on. but nothing happens. no clicks or anything. any ideas?

Hello, You cut the Green wire ok but you or the branch? SamE for the Dark WerE The two Largest over Ews Housing Thank you

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

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 ?

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.

Such a good video !

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

Hi I was wondering if the bypassing on a ews module is the same as a 2003 325i, if so please let me know, thanks your video is a help.
