We report on results for the heavy flavor contributions to F2(x,Q2) in the limit Q2≫m2 at {\sf NNLO}. By calculating the massive 3--loop operator matrix elements, we account for all but the power suppressed terms in m2/Q2. Recently, the calculation of fixed Mellin moments of all 3--loop massive operator matrix elements has been finished. We present new all--N results for the O(nf)--terms, thereby confirming the corresponding parts of the 3--loop anomalous dimensions. Additionally, we report on first genuine 3--loop results of the ladder--type diagrams for general values of the Mellin variable N.
