New DPFEs maybe black plastic but originals were aluminum. Actually its a plugged rear bank pre-cat that causes excess exhaust system backpressure which blows DPFE hoses off. Pre-cats covered by 80k/8yr emissions warranty, except in CA 70k/7yrs.
One member reported a case where an electrical short caused one of the small metal tubes for the sensing hoses to separate at the weld to the main EGR tube resulting in an exhaust leak.
