Thank you ASEMaster6371 for your replay
there is An important point not mentioned previously in last post. I've replaced my oem radio system before this issues com up and installing new After market system (Dynavin D99A for bmw e39 ) with ibus unit. The unit work normal with all option's PDC and OBC features. So it was my belief that the problem is from this unit and I worked the following removed the ibus unit that com whit. And unplug main harness from D99. Today driven my car for 35 mile whit no issues. Could this be the cause of the problem? If this. Is it cause a permanent damage to ecm or other modules.
Thank you for your help.
