Bosch MED17.5.20 Immo Data — for VAG (Audi, Seat, Volkswagen)
Immo Data reads the immobiliser parameters straight from an ECU dump: VIN, PIN/SKC, ISN, immobiliser status and the identifiers of the linked modules. The file is not modified, so the operation is safe and suits diagnostics.
When you need Immo Data
- Buying a used unit — check which car the ECU is tied to before fitting it.
- Key programming — get the PIN/SKC or ISN that your programming tool needs.
- No-start diagnostics — find out whether it is really the immobiliser blocking the engine.
- Cross-checking the modules — make sure the VIN and identifiers match between the ECU and the cluster.
What you get: the immobiliser parameters of the unit are read and displayed — the dump stays untouched.
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 Immo Data 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 «Immo Data» 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.
