P1404 Diagnostic Issue with 2002 VW Golf 4 1.4 16V BCA EGR Valve
I'm experiencing a P1404 diagnostic trouble code on my 2002 Volkswagen Golf 4 equipped with a 1.4-liter 16V engine (BCA variant). The error code indicates that the basic settings for the EGR valve have not been performed. Can anyone explain what this means and how to resolve it? Thank you for your help.
