I get the sound when lifting off the throttle but also when revving to about 1350 rpm. Only happens when (very) cold outside!
at least I am not alone. When I purchased the car in May last year it didn't do it. Neither did it do it through the summer. It only started when the temp outside dropped to under about 15%
