2011 Touareg TDI - I would like to read/write the OEM ecu and save the code. How do I need to accomplish this? Software and hardware. Thanks

If you mean a Tune, you may need a Flash tool, depending on the vehicle, and the tuner. I know for my Treg, the ECU can't be flashed, and has to be removed to upgrade it.
