  This is a note to revisit interesting results of H. Esnault, C. Sabbah, M.
Saito and J.-D. Yu on the Kontsevich complexes from the viewpoint of mixed
twistor D-modules. We explicitly describe the V-filtration of the mixed twistor
D-modules and their relative de Rham complexes, associated to some meromorphic
functions. We explain how such descriptions imply the results on the Kontsevich
complexes.
