SIMOS 8.xx was installed to Audi with large motors. SIMOS 8.1, 8.2, 8.3, 8.4, 8.5 work via OBD, without the need for any action. For 8.3, 8.4 and 8.5 provided the base ori files (full dump, it is possible to upgrade the software). SIMOS 8.6 requires unlocking in BSL mode by the appropriate module. Instructions below.
ECU PCR 2.1 were installed on various vehicles group VAG diesel engine 1.6TDI requires BSL unlocking.
Please note: where available real reading, only the calibration area is subtracted (not the full dump), in this case, pay attention to the version of the calibrations coincided with the current version of SW, otherwise you will get a brick after write. Work very carefully, only SIMOS 8.1/8.2 ECU can be restored via module 53 (Tricore BSL). The rest will have to change to new ones.
Simos 8.4 ECU can also be unlocked, in which case real reading will be available. But I recommend using the ori files that are attached.
ECU marking usually includes another digit at the end of the name, for example SIMOS 8.23. For us it does not matter, from the point of view of the program is 8.2.

The current lock status is displayed when the unit is identified (works for SIMOS 8.4, 8.6 and PCR2.1):

The digital signature verification check: Disabled
If the check is disabled, you do not need to unlock it.
The essence of the unlock-modification of the external EEPROM installed in the unit. So before unlocking it is suggested to read EEPROM and save. For ECUs PCR2.1 loader displays the current lock status when identifying in BSL mode (if set). For SIMOS 8.6 does not displayed.

Each press of the “Initialization”button in BSL mode changes the lock status to the opposite. So be careful what you do.
How to work with blocks that require unlocking (PCR2.1, SIMOS8.6):
1) Check the current lock status in the car, if the check is disabled, you can go to read-write, otherwise follow the instructions
2) Remove the unit from the car, open it, transfer the processor to BSL mode using the connection below (PCR2.1, SIMOS8.6), the work as a whole as in the package 53 (you can use tools like powerbox, and you can do without them)
PCR2.1
Red – +12, Black – GND, Yellow – CAN-HIGH, Blue – CAN-LOW
SIMOS8.6
Red – +12, Black – GND, Yellow – CAN-HIGH, Blue – CAN-LOW
3) Choose “SIMOS8.6 (EEPROM/UNLOCK/BSL) or PCR2.1 (EEPROM/UNLOCK/BSL)” depending of ECU type
4) Click Identification – save ECU data somewhere in a text file.
5) Click Read – save the EEPROM
6) Given that ECU is blocked, we perform Initialization once for PCR2.1 get something like this (for SIMOS8.6 status will not be displayed):
Инициализация модуля
Вход в режим программирования
Передача загрузчика
Проверка
The digital signature verification check: Disabled
Выполнено
On this mission BSL complete. ECU can be closed and put in the car.
7) If you need to return the EEPROM content to its original location, you can select the previously saved file and use the write button.
Work with ECUs after unlocking (2.1, 8.6) or if it is not required (8.2, 8.4, 8.5)
It does not present any difficulties. It is important only to understand that when reading the unlocked ECU you get not full dump, but only calibrations. In this case, recording is possible only if the SOFTWARE version is the same. If ori file was taken from base ori files attached to the module, then there are no such restrictions, the ECU can be “updated”.
