Hi, can you please advise more information of the car for our engineers to check, eg. VIN code, engine type, etc. Thanks!

According to your question I understand you want to replace the Engine ECU rite.................?

Now the replacement ECU is it a new one or, a used one................?  If its a used one than you will need a Pin Code for both ECU........A pin code from a used ECU and from your the vehicle you want to replace it.............And as your vehicle is 2007 Jetta I don't think Autel Tool can extract the pin code from this ECU............you will need to look for a tool which can extract the pin code before you can adapt this ECU to your vehicle.................
