Hello.


VW Passat B6 2009 1.4 TK CDGA 150 h.p. LKP DSG7. This engine does use petrol and compressed natural gas (CNG) methane.
MED17.1
Original ECU with IROM. I have full backup (1037502824) KTAG.
Used ECU with XROM. I need full backup KTAG.


At the factory can be installed 2 types of ECUs - with IROM and XROM under single spare part 03C906021A. These PCBS are exactlly the same with difference between internal or external flash only.
PCB of original ECU with IROM is damaged. I've read it successfully with KTAG, but it's backup file can't be written directly into used unit due to difference in flash implementation. But VIN/CS/PIN can be transferred.



I got such ECU after someone who tried to adapt immo of this vehicle to this used ECU and killed firmware inside CPU Tricore 1796 (maybe trying to write incompatible soft). So ECU can't be identified usng KTAG now. There is no communication with it. But hardware seems to be untouched and in good order.


Does anybody have full backup for KTAG of such ECU with XROM?



Any help appreciated.
