Does anyone know where could I find the EGR valve? I know its usually by the manifold, but with these newer cars never know. Detailed location please.
Thanks,

P0401 is EGR Flow Insufficient. The EGR valve on a Series II 3800 is located on the back side of the driver's side of the engine by the throttle body and upper intake manfold (UIM). The electrical connector is located at the top. There are two 13mm nuts holding the flange.
