MPPS 21, 04L907309L

Hi, my car is AUDI A4 B9 2016 engine DETA ecu number 04L 907 309 L

I have soft 9970 uploaded, I would like to downgrade to 1969, I have mpps v21 cable.
Can I even do it without opening the ECU with this cable?


thank you in advance for all

I will have the original soft from another car, will the VAS 5054A be sufficient? what version of odis do I need?
