On my 2000 Volvo V40 it is located to the right of the gas peddle. I believe that it has a plastic cap over it although mine has been removed. Mine faces the engine compartment but I have seen a V40 (not sure of the year) that faces the gas peddle.
the module is to the right of the gas peddle,bolted to the floor.
