Thank you for your work!
After spending a month to fixing my car again. I'm currently in the process of coding. I was very motivated and killed a zFas control unit.
I was too quick and read the TSB/TPI too late.
!!! Please learn from my mistake and be careful!!!
I found the file for flashing SW 0295 and then unknowingly flashed it via the engineering menu. Big mistake!
I looked for help at Audi and didn't get any. Then I Was able to downgrade the software with ODIS E overnight and for 8 hours with a running engine.
Then I tried again and flashed the bootloader first after TSB. When flashing the main software, the process was aborted due to low voltage. I I used a 30a charger, but the battery was already too weak. The control unit was dead.
A new control unit costs around €4,000 at Audi. So I looked for a used one and got one for €450 with SW 0295 but from an Audi Q8. I didn't want to do any experiments and went back to Audi. They should just calibrate my cameras. But Audi was unable to flash the correct parameters.
Luckily I got help from another forum and someone was able to help me remotely. Flashing also took 3 hours.
An back again to Audi for calibration. Now everything is working so far.
Actually i can use my cameras, but the menu isnt available. Also the 360 view is there. But i can't choose the menu settings. I get no response by touching the Display.
