ZVW  VW DQ500 - reversing back to ori after tune
Hi, I have Multivan T6 with DQ500 transmission, DSG was tuned, but it's tuned incorrectly. Can I reverse it with odis E ?
I have currently 0BT 300 012C sw5302.
Will it work if i flash it with 0BT 300 012A and then back to ori 012C ?
Thanks for any help

Time a go we've working in a ttmk3 with dq250 that was worng tuned.. Laptop goes off when file was writing. In our case we take a complete file from another ttmk3 and path the total back up to first ttmk3. Then we programe cp and flash with the correct frf that we have to buy. 

if the software structure isn't damaged may you could flash with that frf but use the correct file. Other way is taking another back up from other car

flash it straight with 012c, dont need the extra 012a step, it should be fine. Use odis-e
