We construct an explicit free resolutionTfor a maximal Cohen-Macaulay moduleMover a local complete intersection of codimension 2 with infinite residue field. The resolution is minimal when the moduleMis a sufficiently high syzygy. Our starting point is a layered free resolutionL, described in [7], of length 2 over a regular local ring. We provide explicit formulas for the differential inTin terms of the differential and homotopies on the finite resolutionL. One application of our construction is to describe Ulrich modules over a codimension 2 quadratic complete intersection.
