FIXED IT! Problem With speeds off 70 mph and more, I experience wind noise in the A-pillar. I perceive it as a non-constant crispy sound, which depends on the wind speed and direction. Very annoying. It occurs on both sides. Root cause The A-pillar is open on the front end. Air can enter from the fender as well as the windscreen area. This causes vortices in the a-pillar / sound that resonates in the a-pillar. The A-pillar opening is partly closed a by a rubber flap. But this flap is not attached very well and may lose when opening the frunk. Solution Close the A-pillar opening to prevent the vortices / resonance. In order to establish this without dismounting any parts, a sponge can be inserted from the windscreen side to close the A-pillar sufficiently the remove the noise. It appears that this solution not always eliminates the crispy sound, but the overall wind noise. Do-it-yourself 1) by a household sponge like these AH Schuurspons hard bestellen | ah.nl 2) use scissors to cut off a 1,5cm strip as shown below 3) cut off the green part. You don't need that. 4) Push the rubber flap away from the a-pillar opening (as shown below) 5) push the sponge into the hole. Make sure to pinge the sponge with your thumb and index finger so that it will fit through the hole and can expand once inside. 6) the end results should look like this. The yellow stipes indicate the position of the sponge. It doesn't really matter if it sticks into the fender or the A-pillar. The effect is the same. Putting it perfectly into the A-pillar will keep the sponge more dry. 6) put the rubber back in place. 7) enjoy silence 8) donate any remaining sponges to the housekeeper. Disclaimer: a sponge may hold water, causing the a-pillar humidity to be higher than normal. This may cause rust if the a-pillar is not well protected against that. Thanks to the root cause of the wind noise, the sponge will dry quickly with every dry drive.
