I have one FecContainer.fec from VW's discover pro (MIB2HIGH). I did some basic check... The file size should be 4 + (195 x FeC counts). The first 4 bytes means how much FeCs inside the container.
For each FeCs, Start with 0x000000AB and end with 0x000000FF (little endian)
For each offset of individual FeCs
byte00 ~ byte03: 0x000000AB
byte04~ byte05: 0x0211
byte06 ~ byte09 : FeCs in big endian (i.e. FeC 0931002f would be 09 31 00 2f)
byte11 ~ byte15 : VCRN code
byte16 ~ byte33 : VIN + \0 (18bytes)
byte34 ~ byte37 : Date time of the FeCs (Epoch time in big endian)
byte38 ~ byte46 : All 0x00
byte47 ~ byte174 : variant data, signature? (128 bytes)
byte175 ~ byte 178: 0x00000001
byte179 ~ byte182: FeCs in little endian (i.e. FeC 0931002f would be 0x0931002f)
byte183 ~ byte186: 0x00000001
byte187 ~ byte190: 0x00000003
byte191 ~ byte194: 0x000000FF
