It´s possible to create a obd-unlock container with mpps for touareg/phaeton CP04/CP14, release note was only "More types of FRF/SGO added to OBD unlock file function" but in amt-board was some more information. But you always need a sgo for it first from which it is done.

To clarify that, with MPPS you can create "mpps-containers" and "obdunlock-containers" from sgo/frf, also sgo/frf -> bin is available for nearly all MEDC17. Only these containers are flashable with mpps, sgo/frf direct is not possible. This can only be done from sgo/frf, not from bin-file. So if you do not have sgo/frf you cannot use obdunlock, the way with full bin-file similar kess is not possible. He did it this way for safety that nobody can use possibly faulty bin-files from somewhere. Sure a disadvantage, but for most MEDC17 is a sgo/frf available. For these CP04/CP14 are both option available standard container and obdunlock container and there is no hint in k-line container option that obdunlock is not supported. He also posted that these EDC17CP14 k-line is tested, so i assume it should work. Time intensive obdunlock is always done with standard file, after that you can write partial file (also newest MEDC17), so flashing new file to already unlocked MEDC17 needs only short time, no need to make a full flash including unlock every time. There are pro and contra for every tool for sure.

Old topic, but i want to clarify that MPPS RSA bypass is 100% working for K-Line ecu. First time will write about 20min, then you can write calibration only as usual. And no advanced checksum calculation needed anymore, so no need to "patch" in boot / bench before. Untill now i do not know any other tool which is able to do it. Btw you need a good charger, had a constant 80A current while writing with fan on full speed...

No misstyping. 80A during whole 20min flash. There was also brand new battery inside, so all this power was needed for car and most likely running fan about 50A. My 70A charger was at the end, so i connected another 25A charger.
