You guys out there are great at sharing your immensely helpful diagnosis and opinions - I have a weird one for you.
I have a 2006 V but posting to the larger audience here. There is a noise inside the car coming from approx the center stack. It sounds exactly like a bad blower bearing - periodic soft whirring/grinding about 1 cycle/second. It is intermittent, I can often but not always make it stop when I turn the HVAC completely off (power button), however sometimes it takes a second or two after button push to stop. Same with turning on the HVAC and making the noise start. But neither is consistent. It changes tone somewhat with faster engine RPM, but is not directly coupled. It only happens in cold weather and is intermittent enough that it is hard to troubleshoot - not enough time to change all the HVAC settings while it is happening. When it is happening it will last for minutes. I did see in searching the threads that there is a "rolling film" door in these cars - I can guess but I don't have any idea how that works - but since it appears to be a moving element perhaps it's the culprit? By the way it is definitely not the HVAC blower. Has happened two winters now, never heard it in summer with A/C. Any ideas?
