2008 BMW X5 idrive with CAS3++ all keys lost. Autel IM608 says no support for reading ISN for ME9.2. I need long ISN to write to CAS3. What is everyone else using for this DME?
CAS3 could be done via obd2, Cas 3 ++ Istap it best to pull eeprom bin file and make key with DME ISN. It can’t do 64 attempts if it’s got ME9.2 N62 engine ECU, this CAS3 is encrypted. These V8 models can have encrypted CAS3+ asking for 32-digit ISN to decrypt, but DME only uses 4-digit ISN.
AutoHex II, Yanhua Mini ACDP, Ktag boot mode, BDM100, CGpro, MPPS etc. Even then it’s just gonna give you 4 digit ISN, You’ll have to send it to someone with AutoHex and have them convert it to 32 digit ISN! ME9.2 sucks!!
Read ME9.2 ECU with ECU programmers and send dump to someone with autohex to help extract long ISN from flash or read it with autohex/ACDP.
Yanhua ACDP will read both 4-digit and 32-digit ISN code for old/new ME9.2 DMEs
Here is the operation guide to read ME9+ ISN with ACDP.
