Need help Mercedes W164 ZGW

[miki18]

Hello,

Can someone help me with this ML320 W164 ZGW module.

Attached is read of flash and eeprom (29F400 + MC9S12DT254B mask 1K79X)


Friend bought this car (non runner) that was "fixed" by many mechanics and still dead so previous owner sold it.....

I checked few things and firstly I can't do any diagnosis trough obd. Only ZGW responds but no dtcs .... Just like it was erased or in some kind of boot mode (it was also water damaged). I cloned zgw to another used one but same problem. Can lines are OK. Checked with oscilloscope and if I bypass zgw and connect tester directly on PT CAN I can dagnose many ecus....

I know that DAS online would help but I don't have access. I have Vendiamo but I don't know if I can use it for this....

Please help me with those files or suggest me how to proceed.

Thanks

Hello. if you have other control unit, first need reset this module do default, next change vin and coding this car

I thought of that but I'm not shure it would work since I see that used zgw is from W251 not W164.

I can't do coding because I don't have MB online.... I tried to run initial setup but it required MB login....
