BMW F31 acc retrofit help
hello, I retrofitted the ACC on a BMW F31, the system works and there were some errors, I took the BMW to calibrate it, thinking that was the case, but it remains the same. it works for a while and then the error. anyone had a similar problem?
I read these faults with bimmerlink. 1C Integrated chassis management 3 errors 4827BF: LDM function HighLevel operational readiness ACC sensors 48002C: LDM function - high-level operational readiness brake control unit D01B2A: Signal error (actual position EPS, ID: AVL_PO_EPS) - Invalid 29 Dynamic stability control MK60 E5 3 errors 4809AB: Global power supply - external undervoltage D35A53: Signal error (actual steering angle front axle, ID: AVL_STEA_FTAX) qualifier D35A62: Signal error (lateral acceleration center of gravity, ID: ACLNY_MASSCNTR) - qualifier 5D Camera-based driver assist system 1 error E06C43: Signal Status_Availability_Kette_Bremsung received invalid or brake chain not available |

RE: BMW F31 acc retrofit help
Did properly Code everything? With SA Codes did you use?
Does ACC Sensor show up Correctly |

RE: BMW F31 acc retrofit help
Yes, i code 5AS already fitt and add 5DF.
sometimes it is 1 or 2 days without fault and then the fault appears and does not call for a while. I flash DSC, ICM, FRR, KAFAS, FEM to same ilevel. I do not know what else to do. |

I would check the wiring. Had it on an G30 ones. Sensor went on and off. After 4 Hours searching i found a plug that was bad.

RE: BMW F31 acc retrofit help
Did you correctly mount the acc radar bracket? Also if I remember correctly the lower bumper support is different with and without ACC where you put the bracket on. Has that been changed or not needed for your car?
