I'm trying to help a friend out who has an 05 3500 he uses for hot shot hauling. He called me up and said he had a P0046 code, brought it over, scanned it, and there was also a P2536 code stored in the ECM as well. I told him he should probably look for a turbo because it has about 30-40 thousandths of movement up and down in the impeller shaft, and the inside of the turbo is CAKED to beat all get out where the turbo position sensor goes in and solenoid(didn't pull the actual plunger out). So who has a good deal on just a stock reman? Or knows of a low milage take off? He isn't after any real power, just needs it reliable for hauling. The EGR has been blocked since 70K(currently has 240K) miles, EGR tuned out, and no added pulsewidth to it. Just trying to help him keep making money but get a GOOD turbo(not soem parts store junk). We cleaned the solenoid, and position sensor and got it working for him again, but I know it's only a matter of time bvefore it hangs up again. He's pretty puzzled how it has caked up so bad as he always idles it before shutdown, and does oil analysis on every oil change with no signs of problems.
