Viewable online/downloadable from the Bundesarchiv are:

RL 10/576: 3./NJG 11, Kriegstagebuch Nr. 1 (Einsatz: Rheinisch-westfälisches Industriegebiet) (Aug., Okt. 1944; 4. Nov. 1944 –12. Jan. 1945)

RL 10/577: III./NJG 11, Kriegstagebuch Nr. 1 (Einsatz: Rheinisch-westfälisches Industriegebiet) (12 Jan.–5 Apr. 1945)

RL 10/880: 7./NJG 11: Kriegstagebuch Nr. 1 (Einsatz: Großraum Hamburg, Norddeutschland) (5 Apr.–16 Juni 1945)

I think though that these cover mainly operations further north (at least that's what I was looking at) but the last one may help you.
