Could someone be kind enough to provide detailed instructions on replacing an EGR valve on a 2002 C240?

 

its not that very simple it takes about 1 hour you have to remove the the top engine cover, then on the right side of the engine you will find the egr valve, you need to remove the 2 screws that hold the egr valve but sometimes depending on corotion is hard to remove the hose that goes from the engine to the egr valve but puting it back is more simple
