The present invention relates to a vibration damper (1) comprising - a damper tube (2) which is at least partially filled with damping fluid and in which a piston rod (3) is movable back and forth, wherein a working piston (4) is jointly movable with the piston rod (3), by means of which working piston the interior space of the damper tube is divided into a piston-rod-side working chamber (5) anda piston-rod-averted working chamber (6), - a damping module (7) for frequency-dependent control of a comfort bypass which is formed between the piston-rod-side working chamber (5) and the piston-rod-averted working chamber (6) and which has a comfort path via which damping fluid can flow hydraulically in parallel with respect to the flow through the working piston (4), - a control piston (8) which is accommodated, such that it can perform stroke movements, in the damping module (7) and which, at a side averted from the piston rod, delimits a pressure chamber (9) arranged in the damping module(7), wherein the pressure chamber (9) has at least one inlet (10), wherein the damping module (7) comprises a damping module housing with a housing cover (11) arranged at the piston rod side and witha housing pot (12) arranged at a side averted from the piston rod and comprises the control piston (8) and at least one first disk valve assembly (13), wherein the at least one first disk valve assembly (13), in the comfort path, forms a comfort valve together with the housing cover (11), and the at least one first disk valve assembly (13) has at least one bypass control valve with at least one bypass inlet opening (16), wherein, via the at least one bypass control valve, bypassing the comfort valve, damping fluid can flow via a bypass control path hydraulically in parallel with respect to the flow through the working piston (4), wherein the bypass control valve is controlled by means of the stroke of the control piston (8), and wherein the first disk valve assembly (13) comprises at least one bypass disk (17) with at least one bypass disk opening (18) and comprises at least one spacer disk (19) and one comfort disk (20).
