Ecu 8D0907557T does it mean that its not programmable via obd2?
If somebody has a chip for sale for this ecu so send me private message
I think that 8D0907557T is M382 then it is not flashable through OBD2 port, but you can always migrate to a M592 or m383 flashable ECU, like an 8D0907557P M592 ECU.
