EWS 4.3 no crank after reading eeprom

[KZR]

Hello friends,
this is my first post.
A customer of mine tried to change the key battery himself on his last key.

By trying he killed the key.
Car can no longer be started.
Since the car was not close he brought me the EWS4 and the defective key.

Usually I read the eeprom of this EWS with autel im608 and write a transponder with Tango
and never had problems, this time I was too lazy to solder and wanted to use the EWS4 adapter with a real xprog to read the eeprom.

Eeprom read was without erros.
then wrote a transponder with tango.
car can not be started, with key I made.

Now i have an EWS interface error.
I think the eeprom dump is curupt.

What do you think was the problem Xprog or the adapter ?
Could someone of you check the eeprom file ?

EWS DATA:
EWS4.3
PART NO.: 9 127 086
HW: 05
SW: V2 03 0004

VEHICLE:
X3 E83 DIESEL WITH MANUAL TRANSMISSION

thank you in advance

It happen one time to me when read eeprom from CAS3 that XprogM partly erase flash part or MCU. Yours eeprom looks okay. You must read flash from MCU and search problem there.

much thanks to kiszka,

i wrote your file back, this time with autel im608 and made a key with it by using tango.

the engine started immediately.

How you fixed it ?
what tool you used ?

i think you misread the eeprom

[martinsixto47]

I read with vvdi prog first time, test with xp400 and same file. I think vvdi prog corrupted eeprom

Hi,

Why people are bricking those EWS4? I've done like 5 of them with vvdi prog and never had problem but because of such posts I'm always scared to touch it... I read so many feedback and many people use solder free adapters and never messed up, so I don't understand where is the problem?

Maybe the problem lies with the person working on it and not with the equipment
or even equipment, depending on which Chinese hands made it
The friend below knows how it happens

yes it happens that VVDI prog kills this EWS, I killed it myself, a colleague post above helped me to put it up, there are opinions that this EWS is better read with an old R270 programmer, yes, five times you will read the sixth you will fail,
