Hi all, new here.

I recently bought an Audi A4 B7 06 about a month ago. It has done around 50xxx kms when at the time of purchase. So far I love it, and there haven't been any issues. I just recently took it for a service and also got the pink and green slips done. However, I do have a slight concern with the car. There are two separate buzzing noises in the car. The first buzzing noise seems to be coming from the dash. It buzzes when the road gets a bit bumpier and when I accelerate normally. Funnily enough, when I accelerate a bit harder it goes away (weird). The other noise seems to be coming from the front A/C vent. The only way I can describe this noise is like putting paper onto one of those desk fans. I really hope it isn't a major problem but has anyone had any experiences similar to this?

Thanks

I have buzzing noise coming from my dash. I believe it comes from the info screen. Super annoying but I just try to ignore it because it prob a pain in the *** to fix if vw even makes it possible for me to do.

I have a B7 avant, and it makes a buzzing type sound when the car starts. as vce1232000 mentioned, hvac flap motor issue. I researched it a bunch, pretty sure there are threads on here that speak to the issue. I recall some suggesting it's an easy fix, a broken clip that causes the sound when vibrating when moving to adjust for airflow. "Noisy recirculation flap motor" is how i've seen listed on youtube. This may be your issue? It's what i've been dealing with, as it only happens when the car starts, lasts for like 10 seconds, and it's gone. Heat works fine, AC is fine, and all other airflow systems seem good. Here's the youtube link, hope it helps:
