EWS Deletion Chip
One of our customers, Jerryvan Rosado, sent us some valuable information on his experience with this method. It is as follows:
“Thank you for the chip it worked perfect. Just wanted to comment something since I didn’t see it in the Tech docs you guys posted about bypassing the EWS-II system. I installed the chip and cut connection #66 from the ECU but it still needed the key’s chip to start so I went into the EWS Module behind the glove box then cut and joined wires 1 and 3 from the EWS. They are the ignition and switch cables in order to properly bypass the EWS Module. After that, now even my remote started works from up in my apartment with no chip in sight in or out of the car. Just though I could point out that I did since I didn’t see it in your post here at EWS Deletion Chip.
Thanks.

Once again, thank you very much Jerry, for this valuable information. We are sure that you are helping many BMW users by sharing your experience.

First of all, what is EWS? EWS is an anti-theft system installed in BMW cars around 1995 (EWS-II). Later cars use EWS system too, but different versions (EWS-III, for example). It is similar on its idea, to the immobilizer system used in other cars, like Toyota, Honda and VW.

In the 1995 325i / 525i, it is used the EWS-II. Those cars have module (EWS Control Module), pictured above as “EWS II”, that connects to Read the rest of this entry
