so my little china box took a dump and i needed to flash a ecu without the car present. ecu in question is a 03h906032c. Without powering up the ecu reas the e2p from the 95160 with a chip burner then immo off the e2p and write back. little hot air to stick it back to the pads then you can read threw port as if it was in the car. i also realised its dam near impossible to brick the ecu when writing thew obd too i uploaded the wrong file by mistake the first time and to my suprise i was able to recover with just a reflash with the right file. if need be re-enable the immo after. Do not power the ecu up outside the car without immo offing the eeprom first you may be sad if you do

I want to add to this...
It seems that med9 is more forgiving then the masses say. I got a 3C0907115C passat  2.0 fsi ecu. Opened and read the 95160 info offed and put back on the ecu. Then i read the flash threw port. After that I ported the data from the beginning of the original flash all the way to 5A5A5A5A into a 1K0907115B 0040 mk5 fsi file. Flashed the 1K0907115B 0040 to the 3C0907115C ecu without any issues. I used vcds and changed longcoding from auto to manual  and from 3c to1k. Tested no codes car mk5 starts and runs as it should

So you changed the first part of the data in the bin file from start to 5A5A5A5A then inported that data into the 7115B bin file, then flashed  7115C ecu with the bin file of 7115B and the car started.
