  Let $(A,\mathfrak{m})$ be a complete intersection ring of dimension $d$ and
let $I$ be an $\mathfrak{m}$-primary ideal. Let $M$ be a maximal \CM \
$A$-module. For $i = 0,1,\cdots,d$, let $e_i^I(M)$ denote the $i^{th}$ Hilbert
-coefficient of $M$ with respect to $I$. We prove that for $i = 0, 1, 2$, the
function $j \mapsto e_i^I(Syz_j^A(M))$ is of quasi-polynomial type with period
$2$. Let $G_I(M)$ be the associated graded module of $M$ with respect to $I$.
If $G_I(A)$ is Cohen-Macaulay and $\dim A \leq 2$ we also prove that the
functions $j \mapsto depth \ G_I(Syz^A_{2j+i}(M))$ are eventually constant for
$i = 0, 1$. Let $\xi_I(M) = \lim_{l \rightarrow \infty} depth \ G_{I^l}(M)$.
Finally we prove that if $\dim A = 2$ and $G_I(A)$ is Cohen-Macaulay then the
functions $j \mapsto \xi_I(Syz^A_{2j + i}(M))$ are eventually constant for $i =
0, 1$.
