Thanks for posting this.
This has happened to me also although not to often.
1st or 2nd gear at low revs 1500 - 2000 for a couple of seconds. Bit of a worry when you are exiting a parking lot with someone in front of you.
It seems to happen within the first several minutes after starting the vehicle, like a choke is on causing the revs to rise. My D3 has 31k's on it. I will speak to the Dealer when it comes up to it's 36K service interval
