Hello dear members,

I am in desperate need of help to clone a ECU based on EDC17C74. 

Original ECU (Audi A3 2.0l TDI 2018) is damaged due to accident and is not readable (short on board)

So i took another EDC17C74 but with other part number used.

I have an exactly same Audi A3 2.0l TDI 2018 with the same part number (04L906026RJ).

So i tried to clone it with magicmotorsport:

I first read donor ecu of working car, then flash it to used ecu.

Now when i connect to car, it is working but it has dtc internal checksum error and cannot adapt the ecus because it rejects any modification we are trying to do with odis online.

So how can i do this the best way?

Can someone recalculate checksum? or do i need to clone with other tool?
