2002 Jetta GLC: Intermittent loud noise (with vibration on accelerator peddle) that appears to come from under the center of the dash. This happens only on warm days with AC on. If I turn AC off it goes away. When it happens the car loses power.

I beleive I have an answer for some of the related posts.
I recently bought a 2009 jetta. Vibration noise comes at highway speed and comes and goes with the fan or when tailgaiting a truck or not. The vibration frequency does not change with engine speed or road speed. The amplitude changes with wind speed. It can be felt on the steering wheel and pedals.
 
First I thought it was wind vibration of the body screen below the engine .. I modified it and the vibration remained. With that body panel/protection off, I noted the AC fan and water cooling fan hood is very flimsy and vibrates exactly at the same natural frequency as I am experiencing. By now I am so sensitive to the noise that I can hear it at speeds as low as 35 to 40 mph. I tied back the fan hood temporarily and it changed the speed at which it starts.
I am going to request that VW fix this as a warrentee item. It is clearly a design flaw.

#19 of 45 Jetta "squeal" at startup by bizineer

I recently bought a used 2002 Jetta (manual, 2.0, with A/C) with 144k miles. It has started making a short (2-3 seconds) squealing noise at engine startup. The noise seems to come from just to the driver's side of the engine compartment. It only happens at start up and the volume and duration of the noise do change randomly, but only slightly, The check engine light is on and it gives a code that indicates that there is a misfire in the 4th cylinder (it has been reset 3 times and each time comes back with the same code). I do not have maintenance records for the vehicle. Any suggestions?

#20 of 45 Noise under the dash on passenger side by santiael

I have a 2007 Jetta with just over 27,000 miles on it. Recently I started hearing a noise under the dashboard on the passenger side, kind of like a grinding noise, like a bad stepper motor sound. I hear the noise only for a few seconds when I first turn the car on, regardless of whether the engine is on or not. I also hear the noise when I push the air recirculation button on and off, as well as when I put the car in reverse. Any ideas?

Have you had any answers for this? I just started having the exact same problem. I origially thought it had to do with the recirc because mine has not worked in a few months but I also have the noise when I switch between reverse and drive.

Yes. It turned out to be a bad recirculation flap motor (part # 1K0-907-511-C) under the dashboard on the passenger side. It was replaced and noise went away and still hasn't come back.

I just bought a 2006 Jetta. My first one and yes I hear that similiar noise at startup and then after about 30 seconds it goes away and the engine is humming. How much does it cost to replace that flap motor.

I don't know. I took mine to the dealer and the part was still covered under warranty.
