Egr cooler failure due to clogging, happens at regular intervals of about 20-30,000 miles. Dealers/Ford's answer to problem is to 'drive truck like its stolen' this is not an answer. This is a defective in the design of the egr cooler which allows clogging of the system, backpressure and turbo damage. A quick search of the internet show thousands of Ford 6. 7 diesel owners with same problem. Without correction from Ford this will cause owners to 'eliminate or bypass' the egr cooler system, resulting in higher emissions. Someone needs to look into this. It is not correct for a auto manufacturer to dictate how someone should drive a vehicle or to design a faulty component. I am now on my 3rd egr cooler, the last one was not covered under Ford warranty.
