ESYS Activate FA Issue - MobileBmwCoding - 04-11-2020
Alright guys I have a weird issue after trying to code a Cafd backup to a customers car. Customer been having issues with their FRM for a while and had some pretty heavy tunes and retrofits from other shops. The Cafd failed to complete after I click code. After that I was was trying to go through the process of flashing the FRM and learned I can no longer Activate the FA. I tried everything possible and have a backup ESYS and psdzdata program in case it was that and still got the error unable to activate FA. When I use ISTA(D) I get FRM has a short in the communication com bus. I'm going to have the customer replace the FRM but wanted to get a idea from you guys because the FRM shouldn't prevent me from activating the FA.

Hi, i just had a similar issue the Activate FA would run for a few minutes and then fail - try clear all codes using ISTA.
Sometimes there are too many errors in Central Gateway to allow FA to be activated.
My problem occured on F84 - the car had just had BM3 tune and there were about 10 orange modules in ISTA.
Once cleared FA activated no issues.
thanks to my brother @Adel -BimmerFixes-
