  The elliptic flow ($v_{2}$) event-by-event fluctuations in PbPb collisions at
5.02~TeV are analyzed within the HYDJET++ model. Using the multi-particle, so
called Q-cumulant method, $v_{2}\{2\}$, $v_{2}\{4\}$, $v_{2}\{6\}$ and
$v_{2}\{8\}$ are calculated and used to study their ratios and to construct
skewness ($\gamma^{exp}_{1}$) as a measure of the asymmetry of the elliptic
flow distribution. Additionally, in order to check if there is a hydrodynamics
nature in the elliptic collectivity generated by the HYDJET++ model, the ratio
of $v_{2}\{6\} - v_{2}\{8\}$ and $v_{2}\{4\} - v_{2}\{6\}$ distribution is
calculated. The analysis is performed as a function of the collision
centrality. In order to check the HYDJET++ model responses, the results of this
analysis are compared to the corresponding experimental measurements by CMS. A
good qualitative and rather good quantitative agreement is found.
