RPM Fluctuation in lower end

[BumbleBeeTDI]

2006 VW Beetle TDI 6speed DSG w/81k+ miles ~ New DMF
As the title says. I posted this on TDIClub.com and out of 49 current people that have viewed, no one has an answer yet so I figured I would post on here and have a little luck. While in park, if I put slight pressure on the throttle and get the RPMs around 1400-1600, in that range, keeping it steady, it will fluctuate between 50-100 RPMs or more at times, if I give a little more pressure it steadies right out and climbs up just a little past 2k with the turbo fully engaged then.
Along with this it seems to have messed with my 1st-3rd gears. Surges just before it shifts. But, if I go real gentle or a little harder on the accelerator, works perfectly.
Just had the DMF replaced with new good part number. Battery was pulled for over 24 hours during the process. Drove about 600+ miles by now since the battery pull. Hope someone on here can help out or get back to me on TDIclub. Thanks in advance.
