The pressure induced quantum phase transition of the weakly itinerantferromagnet MnSi is studied using zero-field $^{29}Si$ NMR spectroscopy andrelaxation. Below $P^*\approx 1.2GPa$, the intensity of the signal and thenuclear spin-lattice relaxation is independent of pressure, even though theamplitude of the magnetization drops by 20% from the ambient pressureamplitude. For $P>P^*$, the decreasing intensity within the experimentallydetectable bandwidth signals the onset of an inhomogeneous phase that persiststo the highest pressure measured, $P\ge 1.75GPa$, which is well beyond theknown critical pressure $P_c=1.46GPa$. Implications for the non-Fermi Liquidbehavior observed for $P>P_c$ are discussed.Comment: 4 pages, 4 figure
