e61 car thinks it has active cruise control
Hello all
maybe someone can help me. Have customer which came with error - 45F8 - message (torque acc, 0xb7) defective, receiver dde, transmitter ACC/LDM issue is car have ordinary CC, nothing like ACC (b510677). all parts looks ordinary, no other vin in list of units, all units flashed in 2008 last except DDE and CCC. CCC as Headunit cannot have any issues iwth it, and was repaired. So as first i try to recode whole car with VO $540 which was in list correctly saved. Nothing changed, so as next step i try to flash DDE. from UIF 7802544 to 7811481 (btw i have same UIF number, also with basic CC). As next step, i want to flash whole car with istaP to newest istep, which i hope will solve this, but customer is quite away from me, so i want to have some backup plan if this wont solve the issue. |

Is car from factory ACC?
Will normal CC work? There are instructions how to turn from ACC to CC, adaptions from DME(DDE) must carried out. |

RE: e61 car thinks it has active cruise control
what is your customers concern? Is there a check control message on the dash saying Active Cruise Control malfunction?

no check control message, it only don't work, istaD says, there is no message from LDM to DDE (but car never had LDM as it has no ACC or dynamic cruise control)
