Title: Please help Post by: RSC on January 15, 2019, 11:16:29 AM After i broke my original ecu , i boughted an ecu from passat awt me7.5 4B0906018DH 0261207928 and i started to readnit and after that to write my tuned sw from the otiginal ecu (06A906032DE 360165) and after completly wtited ,car doesnt start and vcds dont see the ecu module! Why and where the problem is ? Please help !

Did you drop it... checksum error perhaps? You need the correct ecu that matches your original or something that is known to be compatible with yours.

You need the correct ecu that matches your original or something that is known to be compatible with yours. yes ,original one i droped and broken, first ,when i buyed 2nd ecu (from passat ) i mounted in my car and car started ! After that i readed his flash , and writed my tuned flash from the original one! And ecu was blocked ,vcds dont see it ,car dont started ,and kess cant read/write it in obd ! I removed it from car ,writed it in boot mode with the software with ecu comes and car started ,0dtcs and obd reading and writing is available mow ,but i dont understand why car dont start with my sw , checksumed in ols ,kess do chksum when you write ! So no chksum problems ,no bad tune problems (i think ) but i dont understand why dont work ... same ecu.s me7.5 Title: Re: Please help Post by: Risky on January 15, 2019, 03:48:08 PM The file you are trying to flash isn't compatible to the ecu. For example, 4b0906018DN will not work on a 4b0906018CM even though they are still ME7.5. The part numbers you have are for completely different vehicles.

The part numbers you have are for completely different vehicles. to be more specific, the bootloaders are different, therefore the compatibility issue. me7info will print the BL version in its output. Title: Re: Please help Post by: Risky on January 15, 2019, 05:29:29 PM Quick question. Does comparing EPK lines give us a rough idea on compatibility?
Title: Re: Please help Post by: RSC on January 15, 2019, 10:17:54 PM I thinked the problem is becous i didnt write the eeprom ,pair of the flash in the new ecu! Can the broblem come from here ?

There is no fool proof way to know from just reading the ECU, unfortunately. Title: Re: Please help Post by: Risky on January 16, 2019, 10:56:41 AM Good to know, thank you.
