I made diagnostics with vcds but only error for egr thats why i wanted read it to disable egr..
Maybe someone else try to disable dpf but the new owner of the car dont know for sure so its can be locked by ecusafe.but if its locked possible to write it?

That it is possible to write again, but only with BDM, and just the same file that you read

If the seed key is messed the dealer will not be able to re flash your ECU.

I have the same issue, only BDM readout, repairing seed key and reflash with BDM. But if you have messed eeprom then this will not help you. Then you have to adapt your eeprom too.

I have same problem at my car and I know how annoying is this.

In ECUSafe you just check the check box "Protection", open the file and save it. Put this flash in ECU and try to read via OBD :(.

No way, you will get faulty response from ECU on Seed Key call :).

No need use BDM !!
I have same problem on my golf edc16u1

You have on fgtech tools vag then you must select erase error's. Use that tool(s) and you can read/write the ecu!

Succes

All DTC's were removed (using VCDS).
It looks like ppl who did DPF removal before locked ECU.
