Online VAG BCM2 decoding, changing and cloning tool
BCM2 is the comfort/central electrics module of Audi A4/A5/Q5 (8K), A6/A7/A8 (4G) and related platforms. The service works with the EEPROM dump (95320/95256) and covers the typical workshop tasks: viewing and editing immobiliser data, synchronising BCM2 with ELV and MEDC17, repairing the classic 02811 / steering-defective / ignition-defective errors, and cloning immo data from a damaged unit into a new or used one.
You upload the dump, the tool decodes the immobiliser block, shows VIN, CS, MAC, key data and CRC state, then returns a corrected file. All block checksums are recalculated so the module accepts the file after writing with your programmer.
