i took my car to pull the code and it says P0401 CAUSING ses to come on.should i bring it into the shop?help

 

Yes, I would.....

 

Take in to the dealer. Its EGR flow insufficient. Unless you were messing with your EGR valve, you shouldnt have anything to worry about. They should fix it for you under warranty.

just got back from the dealer and there is nothing they can do till mon when the senior tech comes in.but they said there might be a restriction inside the egr valve.whats weird is that on my way to the dealership the light went off and stayed off

 

any other suggestions guys?ty
