BMW F31 acc retrofit help - Pedrom92 - 15-01-2022
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.

Did properly Code everything? With SA Codes did you use?
Does ACC Sensor show up Correctly
RE: BMW F31 acc retrofit help - Pedrom92 - 21-01-2022
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.

Did you replace your grill?
RE: BMW F31 acc retrofit help - Pedrom92 - 22-01-2022
Yes. Normal bumper. Need put cover.
RE: BMW F31 acc retrofit help - moreply - 22-01-2022
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 - Pedrom92 - 22-01-2022
I will check. but if it was something in the wires you should receive an error message in the ista type disconnected no?

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?
RE: BMW F31 acc retrofit help - Pedrom92 - 22-01-2022
yes it had to be changed too.
