help remote control ezs mercedes w169

[kenza287]

good evening
I ask for your help because I am annoyed
with a Mercedes class A W169
here is the concern is that centralization does not work
I did several tests
I got another mercedes that does centralization the same


by changing esz without just reprogramming the connection the centralization works again but does not start normal


the problem comes from ezs or the key until ok


I have avdi and the virgin avdi which can reprogram the same key as many times as necessary


I reprogram an additional key on each ezs
to see


with ezs original new key starts but still no centralization


with ezs occasion the new starting key is centralization works


I tested the keys if it give the radio frequency
yes it gives all 433mhz


so the problem is not the keys


I then clone the 2 EZS PART eeprom


result is the same centralization works only with the ezs occasion file
and originate cloning with other gives the same result


so it's not ezs in itself
I'm not cloning the flash
only eeprom


so the problem is normally found by elimation on eeprom
origin that does not centralize


because ezs origin I have cloned eeprom from another and the centralization works again but with another car


ezs origin works is does not break physically
the proof


my original eeprom is therefore the culprit


please try to fix it
thank you


I enclose the 2 dump of the esz
