Hi guys,

I've got an issue with HBA (5AC) on an 2008 F01.
Car has kafas, no error on ista (all green). 
With light switch on auto, when i press HBA button, nothing happens: no light on dash, high beam does not turn on with low light.
In ISTA, i can see button status changing ok. 
But if i  code FRM, the HBA works (green light on dash, high beam auto on when on dark roads as expected) until ignition is turned off. 

Any ideas? HBA is original, FRM was replaced a long time ago (on dealer, hw is compatible).
Car has F001-19-07-520 i-level.

Thanks
