Need help on how to permanently disable Bmw Elv direct from the CAS without using the ELV emulator. Thanks in anticipation

To give you accurate guidance, I need a few details first:

• Which CAS version — CAS2, CAS3, CAS3+?
• Part number (HW/SW) from the CAS module label or read dump.
• What vehicle (model, year, engine)?
• What tool are you using to read/write the CAS (VVDI, CG Pro, Xprog, other)?
• Do you already have a full dump of the CAS (EEPROM / flash)?

The general approach involves editing specific bytes in the CAS EEPROM to tell the module that ELV is not fitted — essentially changing the ELV configuration flag so the CAS no longer queries the steering lock. But the exact byte locations and values differ between CAS versions and hardware revisions, so without the info above it's not possible to point you to the right offsets.

Post those details and attach the dump if you can — then we can walk through it properly.

Cas3

CAS3 noted — but I still need a few more details to give you the correct byte locations:

• Part number — HW and SW from the module label (e.g. 9147195 / 9226238)
• Vehicle — model, year, engine (e.g. E90 320d 2008)
• Read tool — VVDI, CG Pro, Xprog, Orange5, other?
• Dump type — full EEPROM read (D80 / 9S12 / 0M89C) or just an OBD backup?

If you can attach the EEPROM dump (or at least a screenshot of the first lines in a hex editor), that will make it straightforward to identify the exact revision and the bytes to modify.
