I have been battling a PO411 code for quite some time. I recently fixed a cracked Vacuum hose and the fittings and hoses seem tight fight. However I do notice a slight gas smell from the engine upon initial start up. This leads me to believe the EGR (Combi/Kombi/air Valve) is not closing.
Does anyone know how to remove this part? Its located behind the air intake below the throttle body. If no solutions on how to DIY how much for the shop to fix or even clean out this part?
ANY HELP IS APPRECIATED THANKS
