In December 2006, while still playing for Osnabrück and was recovering from a cruciate ligament rupture, Feldhoff took over as manager at Landesliga club TV Jahn Hiesfeld,[2] which he was unable to save from relegation to the Bezirksliga.

Immediately before the start of the 2007/08 season, he decided to give up the post again in order to be able to concentrate fully on his active career after a lengthy injury layoff.

[5] In December 2008, Feldhoff was appointed assistant coach of Claus-Dieter Wollitz at VfL Osnabrück under an internship contract that ran until 30 June 2010.

[11] In October 2016, Feldhoff left his job at SC Paderborn 07 to join Bundesliga club Werder Bremen in a similar position.

[15] A year later, at the end of November 2019, Felhoff and Nouri became assistant coaches of Jürgen Klinsmann at Hertha BSC.
