W220 EZS 4J74Y PROBLEM

[mati-rk]

Hi mates. Can anyone can see if this dumps from w220 s500 ezs are correct? Customer told me that car was somtimes started fine but sometimes he can not turn key in ezs. Now i can not turn key, remote doesn't work, keyless go doesn't work. It tells me that key is not present. I think that dump is corrupt. Here is my dumps from EZS. EZS number 220 545 06 08

1- Make new Key.
2- Change 4J74Y to 2J74Y full dump.

Good Luck.

If you desolder mcu , check carefully soldering.

I usually no have 4J but 2J yes.

The two are compatible but can not be read 4J on board.

Try to make the key 8 and see if it works.

I can read 4J74Y on board :) (just EEprom)

HI mates. Thanks to all for help. As panderetamix said i read old mcu 4j74y full dump with ETL. Replaces this mcu with 2j74y. Then programmed new key with AVDI to positon 8. JOB DONE.

[mati-rk]

No advantage. 2j74y and 4j74y are problematic. just replaced to new 2j74y
