Happened to many of us. I addressed it at my 90 day courtesy inspection back in August, in fact it stuck right in their parking lot when I dropped it off. When I got the car back, the paperwork said "no problem found". But they clearly did something, because I haven't had the problem since. Doesn't make sense that they wouldn't want to take credit for fixing it, unless they've got orders from VW to sweep those kind of issues under the rug. Recall avoidance measure perhaps ?
