simos PCR 2.1

[elmer9]

I have a 1.6 75 hp polo,
it doesn't recognize me the ID and if I continue without ID it gives me a wake-up error


The control unit should be a simos PCR 2.1

this ecu is locked by default, either do it obd2 with VR or unlock it in boot mode

Jure, are you coming in zagreb sometimes? My brother has golf 7 2.0 tdi from 2015. And he wants remap. Ecu is probably locked. Can it be done with virtual read, and then flash it. Or needs to be opened with ktag?

[jurebv]

It can be done with virtual read and obd.

[figani]

If it's locked...
It can be done with the most of ori tools by obd...
It needs to be done on bench and or opened...

If it's unlocked before, even a kess Clone can do it by obd...

[elmer9]

blocked means that it does not recognize even id?

[Mooti]

It's best to desolder eeprom with PCR2.1 and insert here to unlock or unlock it yourself
240A to 252
xx xx xx xx xx xx xx xx XOR FF FF FF FF FF FF FF FF FF


There is memory
25640
Read the content and insert here. This will be the best
Then you can use OBD kess for reading

k-tag clone works well
kess clone don’t work

[jurebv]

even kess clone works if someone can get your matching VR from alientech

[vladimir88]

k-tag flex pinout unlock pcr2.1 no need open

[Myjector]

Ktag only original

Unlock then read-write works fine with Kess V2 clone, but obviously genuine tools are best - can be done full OBD no unlock with genuine Kess V2
