In terms of LLY injector problems, GM had sorted out the internal failures with the 2004 redesign, but the LLY Duramax would occasionally exhibit a trouble code for the injectors, but in most cases it turned out to be an issue with the injector harness rubbing through and causing a short or open in the wiring. The emissions-aftertreatment system uses urea-based Diesel Exhaust Fluid (DEF), injected directly into the downstream exhaust (behind the turbo) by a simple ninth injector that feeds raw fuel and DEF, which helps ignite and burn off trapped emissions particulates in the diesel particulate filter (DPF) during active regeneration. In order to meet ever-increasing emission standards and keep up with the Joneses (at the time, Ford's upcoming 6.7L Power Stroke), GM amended the Duramax once more for the 2011 model year. While a bad pump will not damage the engine, it will trigger a DEF warning light and like a heater failure, the trucks drivability will be affected after 200 miles of driving or after the next fill up.
