I did a search but could not find my problem being discussed. While I am listening to the radio it periodically cuts out. At first I thought it was the station but it happens on all of them. I have just noticed it recently and im not sure how long it has been going on. It is hard to recreate on demand but is very annoying when you’re into the song. The only thing I can think is I recently started using my bluetooth phone, but that should not be affecting it. Any ideas?

SITUATION
The customer states that after setting a radio station preset with RDS (Radio Data System) active, and then deactivating RDS, the audio mutes briefly while the customer is driving. CCC-ANT FC "DACA watchdog reset" is stored.

CAUSE

CCC (Car Communication Computer) software error. The problem only occurred after the vehicles software was updated using CIP V19.1, V19.2 or V20.x.

CCC-ANT hardware defective.

PROCEDURE
On a customer complaint basis only:

Using DIS V45 or later, follow the test plan of the GT1 for CCC-ANT FC "DACA watchdog reset". The test plan could have either of the following results:

The test plan result prompts you to program the CCC complete, refer to the following procedure: Update the complete vehicle per SI B09 05 01 (Coding, Individualization, Programming) Procedure B using Progman V21.00.00 (Target Data Status E060-06-03-510, E89x-06-03-510) or higher. After the vehicle software has been updated, turn vehicle off and let vehicle enter sleep mode.

The test plan result prompts you to clear the faults and reset the CCC (press rotary knob along with both drive eject buttons simultaneously). Turn vehicle off and let vehicle enter sleep mode. Retest system and if FC DACA occurs again and only with a customer complaint, submit a PuMA case to the Electrical Group Hotline.

Cool thanx for the info sounds pretty close except im not turning the RDS off and it does it every so often. So I guess a software update is in order.

Thanx a bunch

try turning RDS off and then re-storing all of your fm stations.

this solved it for me.
