Hello,
My f30 has i-step 12-11-504. I have coded it with 3.18.4 and psdzdata 48.1.
After FA coding I decided to update ECU after i did that procedure Connect => Read FA => Activate FA => Read VCM => Left-Click on KOMBI => Click on "Detect CAF for SWE" => Select the CAFD matching your I-Level => Select OK => Right-Click on INHK (the ECU itself not the underlying CAFD) => Select CODE I think I have coded ECU with 12-11-502. If I use 3.128.4 and psdzdata 48.3 can I upgrade Kombi ECU back to 12-11-504?
Thank for advance.
