Where is the EGR valve located on ML?
 

My car seems to have a rough idle. The EGR valve was cleaned once before by the mechanic. Does anyone know where this valve is located on the ML 320?

Thanks,
John

The EGR valve sets at the rear corner of the right cylender head. You will see a steal tube that bolts to it that runs to the intake on the backside between the firewall. The tube is what plugs not the valve, you have to get the tube out and clean or replace it. You have to take the intake tube out to do this.

Is that the passenger side?

Yes, it also helps to see it if you pull the engine cover. ;)
