I've got an '03 Turbo S with the Monsoon AM/FM unit and it has developed a rather strange, rhythmic "pat-pat" sound but only on AM which I listen to the great majority of the time. It's got a certain "rhythmic" quality to it and also could be described as a somewhat muffled "ticking" sound. The sound can be quite annoying, but it's somewhat in the background and doesn't overpower the speech or music coming from the unit. It's been there for quite some time and is more noticeable at various times than at others. Also, at times the unit will inexplicably, suddenly go into "Safe Mode" and remain there for a while, but always comes out of it after a few hours of being turned off or overnight. Anybody else out there have this problem? What could be causing it? :confused:

Thats interesting; I have the same car/head unit; I hear that sound, when I am running a auto scan with VCDS and the radio, happens to be on! I wonder if you are having some connectivity/power issues within the unit or with the connector or a bad/poor connection on the back or with the fuse that is on/in the head unit? :confused:

You have it when you run an auto scan? Well, I have a Scan Gauge II hooked up to my OBD port so now I wonder if that's what's causing the sound and perhaps causing the unit to go into Safe Mode, also? Many thanx for your reply. (at least I'm not the only one who's hearing or heard it..) :)

Maybe; you should pull the head unit, clean all the connections and check the fuse in back and see if it is in good shape... no melted, cracked, have intermittent continuity issues or something. I really like the CRC electrical cleaner; stuff works awesome, available at any auto parts store or even walmart.

CRC Electric Parts Cleaner QD (11 oz) - CRC Industries 05103

QD® Electronic Cleaner, 11 Wt Oz - Product Information

The above; may have nothing to do with it: if you think about it, BOTH VCDS/Scan Gauge II are connected to the OBD II port and access data, so that probably is the cause of it, seeing how the head unit is directly connected to the whole data bus/port. Makes sense to me..
