Hey Guys,

Im using a 07K906032AQ ECU for a 2.5 swap into a MK1 Audi TT

I've pulled the bin file and modified the immo hex and now it states that the immo is basically the same as a new ECU in VCDS

The IMMO chip is 95160 and I had to use CS pin 6.3 to get it to pull the file in argdubs tool.

I have read a lot on this topic but i am still having issues with the checksums.

What does it take to properly check the checksums as Turboat"s tool will not do it as the bin file is 2kb

I will post the fees but i don't want it to be someone does it for me.

Anyone willing to help?

So either vag commander worked and modified it a couple times or I'm doing the checksums wrong.

how can i check the checksums as me7sum and me7check has an error with the file?

Vag com adaptation says 0 on the immo section not 1

Any ideas?

me7sum and me7check are for Flash .bins only, not the Eeprom. The only checksums that would need to be fixed from a normal immo defeat would be the two pages at 0x010 and 0x020.

So change 0x012 and 0x022 (should originally be 01) to 02 and subtract 1 byte from the checksum (last two bytes of 0x010 and 0x020).
