Replaced EGR valve and still getting code P0404
Hi Guys,I had a check light coming on and off a while ago and it was P0404 which relates to the EGR sensor so we replaced it.Well, the check light still comes off and on a few times each month and it's always P0404.Any ideas what else could be causing this?
