Hi, Peter, I hope you are well. I'm sorry to hear you are having issues with your Audi starting and I totally understand how frustrating this can be after already replacing parts. Do you know what scan tool was used to try and reset the safe mode and is it a used module that was fitted?

Customer: replied 13 days ago.
No, I don't know. He tried 2 of them but failed
Customer: replied 13 days ago.
Can the SAFE mode be cleared without needing an auto electrician with a diagnostic machine?
Expert:  Kevin replied 13 days ago.

ok so if a used ECU is fitted it will not work properly unless a dealer online tool is used to remove what is called component protection, sadly there is no other tool I'm aware of that can carry out this procedure

I boufht a used ECU which I took for data transfer. The car is starting but not picking
Expert:  Kevin replied 13 days ago.

ok it sounds like the data transfer hasn't been completely successful and the next step is to get another or get this one on an audi tool

Customer: replied 13 days ago.
I need to contact the dealer not any other garages?

Expert:  Kevin replied 13 days ago.

you will need to go to the dealer as you have to be licenced to use the tool it is not widely avaliable. Thank you again for visiting JustAnswer, please let me know if you need me to clarify anything or if you have any additional questions-I am happy to help!
