Question about 2005 Ford F 250 Super Duty
EGR is at the back of the engine near the fire wall in the middle and is easily accessible. It looks like a 7cm space ship shaped with a vabcuum ine running to a nipple on the top side of it. Below to its rear is the connection to the exhaust feeder pipe. To gain better access you may have to remove the brake booster vacuum bracket held on with a 10mm nut. Loosen the large exhaust pipe nut and then remove the two 10mm bolts that hold the EGR body in place. THe EGR can often be revived by cleaning thoroughly with carburettor cleaning spray and cloth. Clean out the exhaust tube with a bit of frayed brake cable as a tool to brush out carbon deposits. Also check the Differential pressure feedback (DPFE) exhaust sensor: just follow the vacuum line back from the EGR side arm. The DPFE sensor is ten times more likely to be the source of EGR related problems than the EGR valve itself. Please don't get me wrong, cleaning the EGR valve and ancillaries regularly is no bad thing, just be aware of the DPFE sensor.
