Hello All. 1st post here. Short story. Love my R350 2010 Bluetech but it’s not loving me lately with the EGR valve codes and now has another engine light on error p2004 Engine manifold runner stuck control open. Anyone have experience with this? Love this car and nearly get 30mpg on highway so would like to keep but having a hard time finding a shop in Chicago that knows diesel and knows mercedes. Wife would like me to get rid of it if I can’t find an honest shop.
Thanks all
Will of Chicagoland
