Bosch MED17.5.20 Clone: VAG (Audi · Seat · Volkswagen)

Bosch MED17.5.20 Clone — for VAG (Audi, Seat, Volkswagen)

Cloning transfers the immobiliser data and identifiers from the original control unit into a donor one. After the operation the donor answers to the factory keys, BCM and CAS of the receiving car, and no dealer coding is required.

When you need Clone

• Board beyond repair — the board is flooded, burnt or mechanically damaged — the data moves into a donor.
• ECU reads but will not start — the contents are intact while the unit is faulty — the donor receives the same immobiliser data.
• Used donor unit — a unit from another car is tied to a foreign key and BCM.
• No access to dealer coding — the clone starts without a visit to an official dealer.

What you get: the donor unit works like the original — the keys, BCM and CAS of the car accept it without coding.

Bosch MED17.5.20 memory and reading

The Bosch MED17.5.20 unit uses on the TC1766 processor the following: INT FLASH — TC1766, INT EEPROM — TC1766. The Clone operation works on the INT FLASH [TC1766] · INT EEPROM [TC1766] area — that is the one to read out and upload. If OBD reading is not available for this unit, the dump is taken on the bench via Bench or Boot mode.

For the Bosch MED17.5.20 block on the TC1766 processor the «Clone» operation runs online from the ECU memory dump (access — INT FLASH [TC1766] · INT EEPROM [TC1766]). Read the file via OBD, Bench or Boot and upload it — the system detects Bosch MED17.5.20 and checks whether the operation applies for free. You'll get the ready file with recalculated checksums in your portal account.
