any help is appreciated so i got a 2010 328d skid steer. that is in engine derate mode atleast i thank it will only idle up to about 30 %, yesterday morning i started it up to let it worm up for about 5 minutes walked away then all of a sudden the engine went full throttle and blowing black smoke.so i jumped in turned the hand throttle nob but it had no response when turning it. so turned machine off and restated it and it still had same issue. when i checked the codes it had one code for engine derated activated. i let machine sit for few hours. then started it back up and it was idling fine but would only go about 30% idle up i went into the monitors date on the seen and all looks to fuel pressure at 28-30 psi coolant temp it about 178 f, looking at the date for the hand throttle its responding to me turning it from 0%-100% so looks like the nob it working properly. i used the machine in derate mode modt of the day and hopping it will set more codes but no luck.. it has farly new fuel filters, i blow out fuel lines and fuel tank
