We present new phenomenological analysis for the discovery of the heavy neutral MSSM Higgs bosons at the LHC. We analyze the search reach of the CMS experiment for the heavy neutral MSSM Higgs bosons with an integrated luminosity of 30 or 60 fb^-1. This is done by combining the latest results for the CMS experimental sensitivities based on full simulation studies with state-of-the-art theoretical predictions of MSSM Higgs-boson properties. This includes the the variation of the 5 sigma discovery contours in the MA-tan_beta plane with the variation of the SUSY parameters, as well as the precision that can be achieved for a measurement of the heavy neutral Higgs boson masses. It could be possible in favourable regions of the MSSM parameter space to experimentally resolve the signals of the two heavy MSSM Higgs bosons at the LHC. We furthermore present results for the discovery reach in diffractive Higgs production at the LHC. This will allow to probe interesting regions of the $\MA$--$\tb$ parameter plane of the MSSM with the Higgs bosons decaying to b \bar b.
