UPDATE: I was foolish and arrogant during my 2nd attempt at breaking through bmws ews system. I didn't do my homework and that's why I failed. Not this time. ROUND 3! Please scroll all the way below for more info.
Truth and speculations about lies told by bmw regarding their dme & ews. This is a prologue, telling you why I believe it's worth risking over $70 to try this experiment. If I'm right, it will free us all from the chains that bound us from our overlord, Bmw. Don't get me wrong, I love their car and I know that in order for me to be able to drive a bmw, they need to make money. That's all good but what I don't like is people making money off another in a dishonest way. Hey, if a key is going to cost me $300, then tell me that. Don't bs me and say there's a 10 key limit (which I have already proved to be not true. Well, you can't have more than 10 key active at one time but you can have more than 10 keys that was once registered to the car) and tell me that I need to have both my ews and dme switched out afterwards. Come on man. $1800?! Well bmw, i hope my hunch is right about this because if I am, this will be my show of defiance against your ruthlessness against us, the owners.

The following procedure should be adhered to when replacing the EWS 3.3 control unit: Before replacing the EWS3 control unit: Leave defective control unit installed in vehicle and in the coding program (Encoding ZCS) select point "1 New coding -1 Replace control unit - 1 Read out data from defective control unit". Coding data and vehicle-specific data is read out of the EWS control unit with this part of the program and buffered in the MoDiC or DIS tester. Now install new EWS 3 control unit. After replacing the control unit: Encode new EWS 3 control unit with coding program selection point "1 New coding - 1 Replace control unit - 2 Transfer data to new control unit and encode control unit". The buffered data is now transferred and EWS - DME/DDE matching is carried out. Note The procedure described above must be adhered to as all the data necessary for vehicle identification is also stored in the EWS control unit. It will be necessary to do without the data readout from the old control unit only if the EWS 3 control unit no longer has diagnostic capabilities. Proceed as follows in this case: Install new EWS control unit in the vehicle and encode with the encoding program and selection point "1 New coding - 2 Re-encode control unit". Then carry out matching with selection point "EWS - DME/DDE matching". In this procedure, the vehicle data necessary for automatic vehicle identification cannot be written to the EWS control unit.
Replacement of engine control unit (DME/DDE)
After replacing the engine control unit, "EWS - DME/DDE matching" must be conducted with the coding program or in the diagnosis program. Important The ignition must then be switched off for at least 25 s.
Hey guys, I just found this while digging through the wds spaghetti online site looking for a schematic in the dwa section. From. What i am able to translate from what I copied and pasted up there, it seems that what bmw has been saying all along is really a lie. I think what all that is really saying is when switching out the ews, if it's still functional, all you have to do is copy the info from the mcu, and rewrite it to the new EWS or.... Why not write it to a used one? With the ak90, i can even write the vin and mileage to it, so why wouldn't that be possible? Seeing that because the ak90 allows me to add, delete, rewrite keys into whatever key # slot i want to, I wouldn't need a new EWS say for example if i reached the 10 key limit.
If for some odd reason you fry your ews unit, BMW claims your dme must also be replaced whenever you change an ews or vice versa. Now based in what was said above, it states that if you cannot obtain the old info on the ews, all you have to do is install a new EWS, program the dme to recognize that module, which, for almost every single module we know of, all you need to do is write vin and maybe mileage right? For a very long time, none of us really experimented in this area and the hardware wasn't really there for us to connect to the mcu for reading. So what makes the ews any different than say a dsc unit? Nothing really. What did you say? Something about rolling code randomization or complex technical nerd jargon that no longer sounds impressive? Why then does inpa and other software have the option to sync ews and dme code? Lol. The rolling code security feature has now transformed from incredible hulk to a fly on the wall. If at any time your key falls out of sync or you have a key that the ews recognizes and the dme doesn't (or vice versa), syncing them solves that problem.
This all leads me to conclude that all those who have had this lie pulled on them can now realize the truth. When you reached your 10 limit and bmw told you they had to switch out your dme and no, you can't just buy another ews or use a used ews was a lie. All they did was erase all the keys on your ews, rewrote in new key transponder numbers in all 10 key slots (so they can once again control this same process), happily accepted your savings, and laughed as you limped off with your tail in between your legs. I mean, did any of you even see the new units? Oh they looked new to you? If you look at my diy for the ak90 for example the computer board itself, which is covered by a plastic housing, has rarely ever been observed by 95% (or more) of bmw owners, in person with their very own eyes. How would you know? Oh because they told you they did? LOL. All they had to do was change the plastic housing on the outside and you would've never know any better. It probably costed $1 to make, $.05 if they allowed china make it.
What if you fried your ews or dme? If it was your ews, all they had to do was get a new EWS, kept your old dme, program the 10 keys to the ews and sync them together. If it was your dme that fried, they'd just get a new dme, resync it to your other modules and ews, reset the keys registered to your ews, syncing them together and done.
So if all that is possible, I don't need to repeat the obvious and tell you then that in theory, you should be able to use a used ews, and dme (this one I have yet to mess with much but should be no different than any other module) and have it programmed and synced without needing to change both. It isn't that hard, doesn't take much time, and shouldn't cost that much. But because it deals with technology that, especially when it came out, was equivalent to witchcraft. They have done a very good job keeping the lie up, which then kept a lot of people from experimenting, having psychologically implanted failure into their brain. It was a brilliant plan. I mean who in their right mind would experiment on their beloved super expensive bmw to mess with something most knew very little about to test their theory? One wrong move and your experiment fails, which then allows bmw the opportunity to implement their "fact" on your a$$ to show you a real good lesson.
Now, all I need is someone in in the Bay Area with an ews or dme issue for me to try it out on and prove my theory. Message me folks! I will do this for the 1st person with this issue for free as long as you get the parts. Let me know whats up.
