How to Write BMW EWS3 Key with Xhorse Super Chip?
Question: Is it possible to use an xhorse vvdi super chip to start an ews3+ bmw x3 or ews4?
Answer: You can use the super chip to generate all keys lost EWS3 and EWS4 no problem. But no clone (add key).
You just need to preload the chip first then just add key file.
Some people configure the super chip to an ID44 new 7935 to write the chip. It needs luck. A few started and a few did not.
Configure the Super Chip to an ID44 New 7935, if it’s id44 pcf7935, then generate one from xt27 and program it into ews.
Working experience:
1).
Not trying to clone it. I’ve read the ews3+ chip and generated key. First set transponder type as 7935 then make dealer key from dump to position 1. If I select vvdi super chip it says clone start not supported in position so i select 7935 and it makes dealer key but my dump is not modified to write back to chip in ews module so says empty position. Car won’t crank.
2)
Vvdi prog, vvdi2, super chip no problem. I generate once id44 (7935) with super chip and worked just fine.
3). Ews4 didn’t start for me.
4)
Generate id33 vw. Super chip WV id33 will always work, no problems.
If failed, use real 7935 and the original 7935 poof immediately works.
