Stereo problems on cold morning
Thanks for looking,
Went out to the garage yesterday morning on an usually cold day for our area (approximately 2 degrees out) and when I started the car the stereo starting making odd screeching sounds. I immediately shut off the stereo, however I continued to hear odd sounds for the drive in. This included popping/static/screeching and would come and go despite the stereo being off the entire time.
Later in the day the temperatures rose to approximately 25 degrees at which point the stereo worked fine. Is this normal? I'm assuming it was the factory amplifier acting up but haven't experienced this before, even in my other vehicles at the same temperature.

So I am not concerned about it.

1st thing I would try under those circumstances would be to do the MMI reset. Then a VCDS scan as a followup measure for peace of mind.

I have a feeling that it's fairly normal, and that phenomenon is originating in the amplifier. Things like mosfets, transistors, and capacitors all behave differently in the cold. Especially if there are electrolytic capacitors, the electrolyte could freeze, altering the behavior. In my old ford, the gauges would sweep all the way back and forth continuously until it got above 25 degrees inside. It seems electronics don't like the very cold.

I was just about to create a new post when I say this one. My speakers don't work at all until it warms up to at least 10 degrees out. It's getting annoying. At least I can hear the roar of the W12 better.

It was zero out this morning headed to work and once again the stereo was completely silent minus the occasional hissing/popping sound. At lunchtime it was 10 degrees and it works fine. Still seems so strange to have this issue with the Audi. Our other cars (with amplifiers) are all working perfectly.
