Review on Enhancing Engine Performance with Delphi EG10176 EGR Valve by Allan Ryser

Suitable for 2002 sc2. Unfortunately, like the other reviewer, he sets the EGR flow code for insufficient flow (p0401). I made sure the EGR passages in the manifolds are clean and flowing. Replaced with a NAPA branded valve (twice the price) and passed all emissions readiness tests. It may work on an early generation S-Series, but it looks like the valve is not opening far enough to allow the expected EGR flow on a late-generation Saturn S-Series.
