Hello everyone! I need help with the ecu of my audi s3 8pa 2011, it has a med9.1 ecu. While I was reprogramming it to have pop and bang, I inadvertently moved the usb cable a bit and I couldn't recover anything, so my bdm was broken, and my impatience pushed me to solder cables that worked at first but when trying several times I broke the ecu, I know I'm stupid for that... I made an immo off to an ecu with the same reference and adapted it for me car with vag com, everything has been correct except the fuel tank needle, it works badly. Any solution??? How about virginizing if anyone knows or tells me how I can do it? the knowledge. forgive the text. Greetings.
