The pseudorapidity dependence of flow coefficients, $v_n$, is presented over a large range in pseudorapidity ($-3.5 \leq η\leq 5$) in Pb$-$Pb collisions at 5.02 TeV. The flow coefficients are measured with 2- and 4-particle cumulants with $|Δη| > 0$ and $|Δη| > 2$. The difference between $v_2\{2,|Δη|>0\}$ and $v_2\{2,|Δη|>2\}$ implies changes in either the de-correlation of flow vectors or non-flow effects between the two methods. The AMPT model shows a qualitative agreement with the measurements.
