If the VW pump 5Q0 121 599 P is to be replaced by the MSI pump 7.08002.02.0, the VW holder 5Q0 121 093 CH must be removed and replaced with the VW holder 5Q0 121 093 AK if necessary. If the old VW holder 5Q0 121 093 AK is still intact, only the VW pump 5Q0 965 561 B can be replaced. For this, it must be dismantled from MSI pump 7.08002.02.0 in the correct way.
